Minimise Energy helps London university cut carbon emissions by 47%

Minimise Energy has installed new LED lights at London Metropolitan University’s Holloway Road campus, reducing the building’s lighting energy consumption costs by £55,000 a year and cutting annual carbon emissions by 225 tonnes.

The university’s ambitious sustainability programme has resulted in it being named the number one university in England for carbon reduction. The lighting upgrade is the latest part of this programme.

The programme required an eight-strong team from Minimise to replace outdated and inefficient T8 lamps and panels throughout the Victorian blocks which make up the Holloway Road Campus.

“The campus comprises a mix of classrooms, lecture theatres, offices, a gym, dance studios and ancillary spaces,” explained John Hatt, Contracts Director, Minimise Energy.

“Most of the buildings are more than 100 years old and have been subjected to an ongoing refurbishment programme. As a result, the lighting and control infrastructure is complex.”

The LED upgrade was completed during term time, with most work carried out between 7pm and 4am to keep student disruption to a minimum.

“The campus is a 24/7 environment. Meticulous planning and attention to health, safety and on-site security was essential at all times,” said John Hatt.

The LED lighting upgrade forms part of a wider sustainability programme completed by the university under The Mayor of London’s RE:FIT framework.

“The programme was developed to help the university meet the targets set out in its carbon management plan, enhance the student experience, and reduce energy costs,” said Rachel Ward, Sustainability Manager, London Metropolitan University.

The programme also included the installation of photovoltaics (the university’s first renewable energy), energy efficient fans and air conditioning controls. The lighting upgrade was the largest part of the programme.

“This combined approach has been incredibly important,” said Rachel Ward. “We were named as the number one university in England for carbon reduction and have cut carbon emissions by 47%, putting us on track to achieve our 2020 target of 50%.

“The lighting alone is saving us around £55,000 per annum on electricity costs and has reduced our carbon footprint by 225 tonnes of carbon. The lighting has also made an improvement to the feel of the university, making it a bright and welcoming space for students,” she said.

The university is now focusing on ongoing student energy efficiency education, and also plans to instigate further sustainability upgrades in 2017 when it consolidates its three campuses into one.


Venture upgrades high bays to create premium industrial luminaire

Venture Lighting Europe has created yet another highly efficient, energy saving solution for industrial lighting schemes with its new and advanced VLED Highbay Pro. The luminaire is an upgrade of the company’s established VLED IDT Highbays which have been used for numerous applications across the UK.

As the range’s premium product, the VLED Highbay Pro is similar to the original high bays in terms of application, however is more advanced in performance and output, whilst offering a choice of reflectors and beam angles.

Like all of Venture’s VLED luminaires, the Highbay Pro offers a more sustainable and energy saving alternative to fluorescent or HID lamps, which are associated with high running costs and regular maintenance requirements. The superior performance and low energy output of the VLED Highbay Pros will significantly reduce these costs and requirements to provide a fast return on investment.

Available in 100W, 150W or 200W, the VLED Highbay Pro offers a solution for all application requirements and allows companies to use various outputs across the scheme to save energy where possible. The luminaire also offers an excellent efficacy of 100 lumens per circuit watt with an overall package of up to 20,000 lumens to offer optimal light levels across the application. Having such high levels of light can significantly improve the safety of the environment which is particularly crucial in sites that use storage and machinery.

The VLED Highbay can be mounted at heights up to 12 metres with a standard beam angle of 120 degrees for a wide light distribution to cover large areas of factory or warehouse floors, which reduces the number of luminaires needed across the application. Aluminium or borosilicate glass reflectors can also be added to narrow the beam angle to 60, 70 or 90 degrees for a more targeted distribution in aisles or corridors. These reflectors do not affect the quality of light transmitted and are able to withstand the high heat that is generated by the LEDs.

Like Venture’s original VLED Highbays, the Highbay Pro utilises the company’s innovative Integrated Driver Technology (IDT) which incorporates the LED driver into the body of the luminaire. This advanced technology removes the need for a separate driver which will allow the luminaire to achieve its expected 50,000 hour life. This ensures that a lighting scheme does not lose any light from failed products which could compromise the safety of the environment.

The luminaire also adopts the original VLED Highbays’ incorporated smart heat-sink unit to maximise the dissipation of the heat from the LEDs. This built-up heat is known to damage the performance of the luminaire and reduce its life expectancy. Having this highly efficient thermal management system also ensures the 50,000 hour life is achievable. The luminaire carries a five year guarantee.


Outdoor portfolio with high overvoltage protection

 TALEXXdriver Premium OTD devices can withstand 10 kV

 Virtual midnight function offers additional savings

LED street lights and outdoor lights can be professionally dimmed with voltage-resistant TALEXXdrivers in the Premium OTD series from Tridonic. These drivers for luminaire installation offer impressive surge/burst resistance of 10 kV and are extremely durable with a life of 100,000 hours.

Tridonic has extended its outdoor portfolio with the addition of the TALEXXdriver Premium OTD series for professional dimmable LED lighting solutions in luminaires of protection classes I and II. The drivers are housed in a fully encapsulated enclosure and are particularly suitable for use in harsh ambient conditions outdoors, providing reliable, flexible and cost-effective lighting with a high level of efficiency. There are five different versions with different outputs and variable output currents.

TALEXXdriver Output Adjustable output current
LCA 30W 250–700 mA one4all C PRE OTD 30 W 250 – 700 mA
LCA 60 W 350-1050 mA one4all C PRE OTD 60 W 350 – 1050 mA
LCA 75 W 250-750 mA one4all C PRE OTD 75 W 250 – 750 mA
LCA 120 W 350-1050 mA one4all C PRE OTD 120 W 350 – 1050 mA
LCA 160 W 350-1050 mA one4all C PRE OTD 160 W 350 – 1050 mA

All the versions are equipped with one4all (DALI DT6, DSI, corridorFUNCTION) and ready2mains™/U6Me2 (chronoSTEP 2) interfaces. The drivers therefore have the flexibility to meet different lighting requirements. Luminaires can be easily configured via the power cable with the aid of the ready2mains programmer so there is no need for an additional communications interface. During production the ready2mains enables output currents to be set and tested, and dimming commands to be defined. Integration in automated test processes is also possible. Outdoors, ready2mains can be used to program individual LED street lights, or entire street runs can be programmed from the switching cabinet via the U6Me2 communication protocol with a high degree of flexibility. The chronoSTEP 2 function, which is also known as virtual midnight, offers additional energy savings. It takes into account reduced traffic on the streets at certain times during the night and enables the lighting to be programmed in eight individual dimming levels and times.

In accordance with their intended use outdoors, the drivers operate reliably in an extended temperature range from -40 to +70°C. Standby mode is particularly economical with a power draw of less than 0.16 W.

Funding scheme dips the lighting bill for Valleys authority

Local authorities across the UK are facing the challenge of providing high-quality public services at times of budgeting. To counter this, many are recognising the benefit of investing in energy efficient street lighting technologies as an effective means to drive down energy bills.

Street lighting across the UK is estimated to account for over a million tonnes of CO2 emissions annually, which is enough to fill the Wales Millennium Stadium in Cardiff 35 times with the roof closed. 1 The majority of the street lighting facilities are outdated, inefficient and extremely costly. Energy prices have risen 20% since 2009 and recently published National Grid forecasts suggest the price of electricity could double over the next two decades2.

With this is mind energy efficient street lighting is a smart investment option for local authorities, but many struggle to find the finance upfront to invest in these high-quality, modern lighting solutions.

The lack of up-front capital and minimal funding can often act as a barrier to many otherwise willing authorities. However, an increasingly popular Government-backed support programme is now helping to plug that gap for public bodies by making finance available for energy efficiency improvements, which can be cost-neutral in the short term and make significant carbon and financial savings in the medium to long-term.

Interest-free funding from the organisation Salix Finance provides the ready capital needed for local authorities to implement energy efficient lighting upgrades across cities. Salix is funded by the Welsh Government, the Scottish Government and the Department for Energy and Climate Change to support energy efficiency projects, such as street lighting upgrades, to cut carbon emissions and reduce energy bills.

Merthyr Tydfil County Borough Council is a recent example of a local authority that has identified the opportunity to lower its energy bills by updating a number of its street lighting technologies across the county. Similar to many other local authorities, it lacked the initial capital required to implement these technologies.

The council approached Salix Finance who were able to provide an interest-free loan to help revamp the street lighting across this industrial area of the South Wales Valleys.

The project was completed in four separate phases at four different locations of the county taking place across the course of a year. The projects required a loan of just over £2m to replace the outdated, SON-T lighting to a modern, LED replacement.

The upgrades to the council’s street lighting will see the county cut its annual energy costs by a projected £370,000, amounting to savings of more than £7.4m over the lifetime of the project. In addition to this the scheme will save more than 1,400 tonnes of CO2 each year, amounting to 28,000 tonnes over the project’s lifetime.

The loan will be paid back over 5 and a half years funded from the savings to the council’s annual energy bills which means the project is of no extra expense to the Welsh local authority and effectively pays for itself.

Chris Ridout, Street Lighting Engineer for Merthyr Tydfil County Borough Council, said: “After attending a Salix Finance seminar in Cardiff around three years ago, we were instantly interested in working with the company to reduce our carbon emissions and running costs for our street lighting. Since the LED installation has taken place we are currently saving around 75%, which is higher than we ever expected.”

Tim Morozgalski, Programme Manager for Wales and NHS England at Salix said: “Merthyr Tydfil is an excellent example of installing street lighting in phases across the County. Since 2014, they are expected to have rolled out £2m of LED street lighting in two years. By splitting this large-scale project into phases, it has allowed the Council to start achieving carbon and financial savings road-by-road. LED street lighting in proving popular amongst local authorities in the United Kingdom and we will be holding street lighting workshops in Wales to help support other Councils that are interested in getting interest-free loans to install new LED lighting and controls upgrades.”

With a wide range of technologies available, building managers from across the public sector are faced with the difficult task in driving forwards with a low carbon behaviour change, but options such as a Salix loan, make the task a smooth process.

To date, Salix has financed over £85m worth of loans to complete street lighting projects across the UK, resulting in over £315m in lifetime savings.  In addition to this, its work has saved over 1.3m tonnes of lifetime carbon savings.

The establishment of the Salix investment, which is available to all local authorities across England and Wales, makes energy improvements in the public sector available. Furthermore, repayment instalments for the loan are usually covered by the sum saved through the immediate and often dramatic reductions in regular fuel bills.

Eaton Expands LED range for Efficient Lighting in Industrial Buildings

Power management company Eaton is aiming to improve the quality and efficiency of lighting in industrial buildings by expanding its range of robust LED luminaires. The new additions to Eaton’s comprehensive lighting portfolio are the Tufflite and Linergy LED luminaires. Additionally, its existing Litex family of products has been updated with the addition of next-generation LED technology.

Andy Gallacher, lighting product manager at Eaton, said: “There is huge potential for industrial buildings to increase energy efficiency by switching from older fluorescent or high intensity discharge luminaires to the latest LED technology. This can not only reduce running costs but also saves on maintenance due to its longer lifespan. In warehouses, for example, lighting can account for up to 70 per cent of energy usage, while the figure is around 35 per cent for manufacturing sites. However, while the potential savings are significant, there’s also an urgent need to improve the quality of lighting in many industrial buildings, which have traditionally suffered from poor performance in this regard. Better lighting can have a major impact on the general wellbeing, productivity and safety of building occupants. Eaton’s latest Linergy, Tufflite and Litex LED luminaires have been purpose-designed to help those responsible for industrial buildings meet these objectives.”

Linergy LED follows in the tradition of Eaton’s highly efficient large-space luminaires which have the performance and flexibility for today’s multi-use and multi-occupancy locations. Incorporating the latest LED light engine technology, the luminaire delivers high lumen outputs and class-leading efficacies of up to 115 lumens per circuit watt (Llm/cW). When combined with the integral occupancy and daylight sensors, this can offer substantial energy savings for the end user.

The versatile Tufflite LED luminaires, with IP66 rated ingress protection, are suitable for areas where protection of the luminaire from environmental effects is vital. Offering a comprehensive range of lumen outputs across three lengths, the versatile LEDs are ideal for new and retrofit applications in warehouses, car parks, assembly areas and loading and storage spaces.

Additionally, Eaton has added new-generation LED options to its Litex range to improve the luminaires’ versatility and performance in industrial and warehouse environments. The enhanced Litex LEDs offer a 15 per cent rise in lumen (lm) output and are available with a choice of lumen packages controlled by open area, rack aisle or narrow distribution reflector options. Additionally, the new luminaires are designed to accommodate different mounting heights and installation methods, resulting in a solution that can be tailored to diverse applications.

Let there be Lumie!

Sunshine is clinically proven to make us happier, but is something often in short supply during a British winter (or summer for that matter). A continual lack of natural light can cause serotonin and melatonin levels in the body to drop, triggering the symptoms of depression. Up to 24% of the UK population experience the winter blues and of those, around 7% have such bad symptoms, known collectively as Seasonal Affective Disorder or SAD, that they struggle to function normally.

The lightbulb moment

Since 1991, Cambridge-based Lumie has been at the forefront of safely and effectively fighting off the winter blues and SAD with light therapy. “Our founder Steve Hayes identified a need for light therapy products in the UK,” says Jonathan Cridland, current CEO of Lumie. “He developed a light box to increase the body’s natural production of mood and energy boosting hormones, such as serotonin.” Lumie later went onto invent integrated dawn simulators, also known as wake-up lights.

Dawn simulation is a method of resetting the body clock to adapt to a new sleep/wake cycle by simulating the rising and setting sun. This can benefit people, who struggle to wake in the morning, shift workers, travellers suffering from jet lag and SAD patients. The Lumie Bodyclock range features a simulated sunrise and sunset to help people wake-up and fall asleep in the best way possible.

Exporting “sunshine”

Based on rigorous research and innovative design, and classified as medical devices, the company’s diverse product range has seen turnover grow by 50% in just four years. Lumie is Europe’s leading light therapy specialist, with customers throughout Europe, North America and Australia. “The interest we’ve had from Europe, especially further north where winters are long and dark, has been phenomenal,” says Cridland.

Many hands make light work

As a product used to treat medical conditions, customers are keen to receive their Lumie as soon as possible so they can begin to enjoy the benefits. This means on time delivery has always been important. Following such rapid growth and international expansion, the challenge is maintaining the highest levels of customer service – even when transporting to the other side of the world.

That’s where FedEx comes in…

lumie2“We’ve worked with FedEx for ten years and they ensure our shipments arrive on time and in perfect condition”, comments Eileen Somerville, Warehouse Manager at Lumie. “The couriers take the utmost care when delivering fragile items, making sure the bulbs are kept upright and secure in transit.”

Lumie uses the FedEx order management system, available via an enhancement of the standard FedEx Ship Manager® Software, to process orders and streamline administrative functions, such as shipping label generation. “This certainly brings structure to our process management procedure and for any unusual orders, the FedEx IT support team is always on hand,” explains Somerville.

Local FedEx UK depots also adapt to Lumie’s increase in daily collections during the autumn/winter period and the run up to Christmas. “FedEx recognised that we experience an influx in orders during certain seasons,” adds Somerville. “It factored this in to our shipment needs and adapted, effectively providing us with seasonal shipping slots”.

The future’s bright

Research and innovation has always been central to the Lumie success story. With its new product Lumie Bodyclock Iris – that combines a wake-up light with aromatherapy for the first time – the company has big plans to continue this trend on an international stage.

“As we continue to grow and expand into new markets, we’re going to need a logistics provider who can deliver to the same high standard of customer service,” adds Cridland. “The global-yet-local expertise FedEx has is a big bonus in this area, and we expect FedEx to be a part of our growth for years to come.”


Why wireless control brightens the effect of LED lighting

LED lighting is revolutionising the lighting industry and creating completely new market conditions. However, unlocking its full potential has been hampered by a lack of simple and easy to install industry standard solutions enabling personal control, energy conservation and compliance with increasingly stringent building standards. To fulfil all of these requirements, LED control based on standardised wireless technology is the way forward. By Matthias Kassner, Product Marketing Director, EnOcean

With LEDs replacing old lighting technologies, new control capabilities enable building owners to achieve higher energy efficiency rates and increased comfort. Fulfilling this potential requires selecting a suitable control solution. As the lighting market is still evolving, different standards and architectures exist for lighting control to cover the comprehensive requirements of changing colours, dimming, occupancy-based on/off, demand response or sophisticated daylight harvesting.

Stringent regulations

Building owners demand reliable systems at reasonable costs, which forces the lighting industry to provide a comprehensive but easy to install control solution. This goes hand in hand with regulations, such as the EU Directive for the Energy Performance of Buildings, which became a vital part of building regulations in a drive for greener buildings. It aims to make energy use in buildings transparent by issuing Energy Performance Certificates (EPC) as well as identifying and developing new opportunities for a reduced carbon footprint.

Besides this, green building certification programmes such as LEED or BREEAM call for integrated control of building areas for the achievement of the maximum number of points. Here, the meaning of lighting control is still significant: 30% of lighting energy consumption is still wasted on average when rooms are not in use.

The limits of wires

One option for installing LED lighting control is a wired system. This is mainly suitable for simple use cases where all lights are connected to the same bus and set to the same light intensity. But wiring complexity grows significantly once the system is required to control a set of lights together. Furthermore, an upgrade from a simple scenario to an advanced control system cannot be implemented without costly changes to the existing wiring and the controller. In addition, it is almost impossible to include sensors, for occupancy detection or daylight harvesting for example, to achieve optimal energy saving rates.

For retrofit projects in particular, the installation of wired controls can be complex, costly and time-consuming. Modernising an existing building with wired control systems requires the addition of dedicated control cabling to each individual lamp. Each element, such as switches, sensors and lights in these systems requires dedicated cabling as well.

Wireless flexibility

An alternative to a wired system is wireless control. It has increased in popularity in the last decade due to advances in radio technology and the emergence of standards which enable seamless communication between different devices. The key advantages of wireless control are the ease of upgrading existing buildings and expanding a system at any time. No new control wiring is required for existing lights; they simply have to be upgraded with wireless control units. Wireless control systems can potentially also provide greater installation flexibility if units within the system do not require dedicated cabling for power.

Building standard

Several standards already exist for wireless communication in a building automation system. The energy harvesting wireless or so-called EnOcean standard is one of the most established. It is defined by the EnOcean Alliance, a consortium of international companies of the building automation industry. The wireless communication uses the 868 MHz frequency, which delivers a distance of up to 30 metres in buildings and has no interference impacts from local Wi-Fi or Bluetooth devices. RF reliability is assured as wireless signals are less than one millisecond in duration and are transmitted multiple times for redundancy. These characteristics make the standard well suited for wireless lighting control in larger buildings with a few hundred wireless sensor nodes up to several thousands.

Elimination of batteries

The standard is optimised for ultra-low power communication, which allows the use of battery-less, self-powered sensors and switches. For lighting control purposes, the two main energy sources for battery-less, wireless devices are motion and light. Self-powered switches use kinetic energy to generate a wireless signal for controlling and dimming. The second energy source is provided by miniaturised solar cells which harvest ambient light and convert it to electrical energy. This approach is particularly suitable for light level or occupancy sensors. Based on standardised application profiles, energy harvesting wireless devices from different vendors can seamlessly communicate with each other. This approach of open connectivity and interoperability offers the conditions for an integrated LED control.

Holistic approach

The energy harvesting wireless standard enables a complete wireless LED control system for retrofit projects. Solutions based on this standard include LED controllers, solar-powered occupancy and light level sensors, kinetic-powered light switches and a remote commissioning software tool. The controller wirelessly communicates using the energy harvesting radio standard at 868 MHz. Via this protocol, it receives wireless telegrams from all linked self-powered wireless switches and sensors and adjusts its outputs accordingly. It provides a switched output for the supply of connected loads as well as a control output to dim connected loads. Multiple fixtures can be daisy-chained, e.g. 20 each 30W fixtures or 10 each 60W fixtures.

This system can support a wireless daylight harvesting application, for example. Daylighting means that the light level is automatically adapted to the amount of available natural light in a room measured by light level sensors. In a typical commercial building, it is possible to save between 20% and 30% of energy with such an automated control system.

Basis configuration

The wireless controller supports several usage scenarios. In a very simple configuration only wireless light switches will be connected for manual control of the lights. If desired, it is possible to configure an auto-off timer which turns the lights off after a certain amount of time as is usually used in stairwells. Another basic installation can be implemented by connecting occupancy sensors, which sense motion in a room and send wireless signals to the controller, which controls LED lighting according to occupancy. Both the standard on/off configuration as well as switching between two dimming levels is possible. The latter case is important in applications where a minimum light level must always be maintained. Instead of an on/off configuration, the occupancy sensors’ signals can also be used to set different dimming levels in the range between 100% and 0%.

The combination of occupancy sensors and rocker switches enables the user to manually turn on the light, whereas the occupancy sensors automatically switch off the light after a pre-configured period of time when the room is unoccupied. Light can be automatically turned back on if occupancy is detected. In this scenario, the occupancy sensor can also be used to switch between a high and a low illumination level and the switch can be used to turn lights off completely.

Sophisticated control

The addition of a light level sensor allows the implementation of daylight harvesting based on open loop control. This means that the light sensor, positioned facing a skylight or window, measures the amount of available natural light and regulates the output light level accordingly. The lighting controller will then only add as much artificial light as needed. In a simple configuration, the system will change between two levels, a minimum and a maximum dimming level, depending on light levels reported by the light level sensor and signals from occupancy sensors and switches. In addition, it is possible to set up a more sophisticated daylight harvesting scenario which supports continuous dimming based on five sampling points which can be defined via remote commissioning software. In both scenarios, illumination will change smoothly by means of adjustable speeds which can be independently configured for manual changes via rocker switches and automatic changes based on sensor signals.

Configuration over the air

More advanced settings, such as thresholds, dimming levels, ramp speeds, or timers can be changed wirelessly via a remote commissioning interface. By employing a Windows-based laptop computer equipped with a remote commissioning tool, an installer can locate wireless devices throughout the facility, logically connect the controller to switches and sensors, and configure settings in the controller over the air, all completely without physical access. It is also possible to link the LED controller via a central unit or a gateway to a supervisory building automation system like BACnet or KNX.

Low installation effort

Thanks to wireless technology, all of these scenarios can be set up quite easily at low installation costs and only require a minimum of maintenance. Therefore, building operators can fulfil regulatory requirements and achieve immediate energy savings and increased comfort with low investments and a fast return on investment (ROI). The wireless sensors and switches can be flexibly and optimally positioned without requiring repair to walls or ceilings. Due to the self-powered operation they even eliminate the need for changing batteries.

The LED controller’s compact size enables flexible installation inside of or next to electrical boxes and fixtures so it can be easily wired out of sight using standard wiring practices. Wireless lighting control also enables a migration path, starting with simple control and expanding the system with advanced functionalities such as scheduling, demand response or remote commissioning later on. As the LEDs can be digitally addressed, they can also communicate with each other and a central control. This enables the building of groups of light, which create optimised scenes in accordance with changing situations.

Seamless communication

Wireless standards offer valuable benefits to LED control by following an integrated approach consisting of accessories, software and easy-to-use commissioning tools. At the same time, they combine control functionalities and networking abilities with a consequently standardised communication. The wireless technology allows users to easily install, retrofit, move and commission LED lighting control even in complex systems achieving large scale economies.

Feel-good light for offices, education and healthcare facilities

Tunable White now available for area luminaires

Tridonic has expanded its product portfolio in the Tunable White segment with the addition of the square TALEXXengine QLE PREMIUM LED module. This has been designed specifically for area luminaires in healthcare facilities, offices and educational establishments. People, be they patients, staff or students who spend many hours in artificial lighting will be the main beneficiaries.

“Natural daylight has a positive effect on our well-being, health and productivity. It helps alleviate mood swings and keeps our biorhythms in balance. Dynamically adjustable light that changes over the course of the day has a comparable effect,” explains Martin Thompson, Technical Services Manager at Tridonic. The new offering is a square lighting solution known as the Tunable White Area System, which is tailored precisely to the area luminaires often found in healthcare facilities, offices and educational establishments..

Product Details

The Tunable White Area System is available as a precalibrated set that provides optimum quality of light and high colour consistency. It consists of four square LED modules each with a luminous flux of 1250 lm and one low-profile LED driver with a one4all interface (DALI Device Type 8, DSI, switchDIM, colourTEMPERATURE) and an output of 75 W. System efficiency is more than 130 lm/W. Thanks to the calibration the colour temperature can be set dynamically between 3000 K and 6000 K, with the luminous flux being kept constant. In addition, the system can be dimmed from 100 to 10% without changing the colour temperature. This means that it is able to achieve an excellent system colour tolerance of MacAdam 3.

Integrated thermal management ensures that the system does not require separate cooling. The long life of 50,000 hours reduces maintenance requirements considerably and the economical LED light sources and dimming function combine to provide a high level of lighting comfort and a reduction in energy consumption.
