LED downlights

04 April, 2012

Base LED junior is a smaller version of Thorn Lighting’s replacement downlights for halogen and CFL fittings. The new downlight comes in two versions — one for high performance (650 lm/11.5 W) and one with a deeper recessed lit surface for added comfort (600 lm/11.5 W). Both use Cree’s True White technology to deliver high-quality light (3000 K) with Ra 90 stable colour rendition.

Lighting, LED, Havells-Sylvania

Havells-Sylvania has launched a range of downlights using LEDs with very high outputs for large spaces with high ceilings such as airport terminals, museums galleries and retail outlets with high ceilings. Concord LED Performance Cones can achieve a 2000 lm package from a 50 W LED lamp — equivalent to a 100 W low-voltage capsule lamp.

Lighting, T5, LED, Cooper Lighting & Security

Recessed luminaires from Cooper Lighting & Security use T5 fluorescent lamps for the main lighting and an integral LED with purpose-designed lens for emergency lighting. Lechenti luminaires are available in fully recessed or semi-recessed formats and suitable for lay-in or draw-up installations.

Lighting, LED, Tridonic

Tridonic has developed compact linear LED modules that can be combined in lines to create strip lighting as an energy-efficient replacement or alternative to T5 or T8 fluorescent lighting. The Stark LLE modules measure 35 x 270 mm, and up to five can be operated with a single TALEXXconverter.

Newey & Eyre has introduced a high-quality high-output LED downlight kit that is compliant with Part L (parts A and B) and ideal for applications where high-quality lighting and zero maintenance are required. The Allom kit includes driver, LED module and anti-glare downlight with a lifetime of 70 000 h (at L70).

Lighting, LED, LED Exchange

As an alternative to MR16 low-voltage halogen lamps, LED Exchange’s ALT V% LED lamp uses just 7 W to deliver 520 lm at a warm-white colour temperature of 2800 K, 85% less than the halogen equivalent. The heat sink is said to be so effective that the lamps have a life of 30 0000 — over 10 years based on an 8-hour day.

Lighting, Vita Energia

Research by Vita Energia suggests that energy consumption for lighting in factories and warehouses can be reduced by an average of 58% by upgrading lighting fittings with specially designed reflectors and installing lower-wattage high-efficiency lamps and ballasts. The survey involved over 500 sites with a fairly typical double-shift patter of 100 h a week (5116 h/week). A 12-month payback was achieved by facilities operating for 6936 h a year and 12 to 24 months for fewer operating hours.

Fast panic-free evacuation from burning buildings is crucial, which is why UK legislation demands reliable, good quality emergency lighting. Bernard Pratley explains how the latest generation of white-light LEDs provide highly effective escape-route lighting.

Ridi, lighting, prewired lighting trunking

The first of 50 Lidl stores in the UK to be fitted out with Ridi’s prewired lighting trunking system is at Braintree. The UK stores are part of a European-wide contract that has already seen Ridi upgrade lighting in most of Lidl’s 1500 stores in France, as well and in Switzerland, Germany and Poland.

MK Electric, Echo, lighting control

MK Electric has extended its Echo range of self-powered switches with a combination switch receiver and repeater. The K5420R is designed mainly for installing in ceiling voids for wiring into the lighting circuit. It reduces the stock required to wire an installation because when installed and powered but not programmed with transmitters it will also work as a repeater.

LED lighting, Dialight

LED lighting installed in various areas of the ExCel exhibition and conference centre in London has considerably improved the quality of lighting and is achieving significant energy savings. The new lighting has been installed in the central boulevard, which is over 700 m long, the entrance canopy to the conference centre and the walkway alongside the adjoining dock.

Steinel, control Pro, presence detector

Steinel’s Control Pro system of presence detectors for controlling lighting have square-shaped detection characteristics that are said to be better suited to the layout of rooms such as offices and conference areas than the round attributes used by conventional presence detectors. According to Steinel, ‘Never before has it been possible to cover offices and commercial areas with presence detectors without overlaps or leaving gaps. Using Control Pro, zones can be planned perfectly, with reliable detection at every point of the room and up to 4800 switching zones.’

Finder, PIR, lighting control

Additions to Finder’s 18 Series of PIR motion detectors can meet the needs of applications with higher ceilings, higher loads and those requiring direct interface to a PLC or BMS. There are two versions, one for flush fitting and the other for surface mounting.

Ex-Or, lighting control

The installation of Ex-Or lighting-control modules in 55 London fire stations to date is typically reducing energy costs for lighting by about 20%. Ian Shaw, environmental and energy-efficiency office for London Fire Brigade, explains, ‘Typically, lighting accounts for around 70% of the electricity load at each fire station. The average lighting bill per station is £10 000. To date, we are achieving annual savings of £120 000. Once the entire estate has Ex-Or’s equipment installed, we will be making savings of almost £250 000 each and every year.’ [There were still 50 more stations to be completed.]

T5 fluorescent lamp, Osram

The latest addition to Osram’s T5 range of fluorescent tubes has a life of up to 45 000 h, good for applications where replacement is difficult and costly. Lumilux T5 high-output XT tubes are available in 54 and 80 W versions and a range of colour temperatures. They are perfectly matched with Osram’s Quicktronic electronic control gear.

Lighting is the second biggest use of energy in London, making it a prime target for energy-efficient control. Darren Burford takes up the story.

Save It Easy, Energys Group, T5, lamps

Relamping with T5 fluorescent lamps in old fittings has reduced lighting energy costs at a garden centre in Hampshire by 44%. The use of the new lamps was made possible using the Save It Easy retrofit converter device from Energys Group. The 8 ft tubes previously used were very expensive, tended to lose output quickly and produced a rather yellow light.

Totalight is offering dimmable LED lamps that can directly replace 50 W GU10 halogen lamps free of charge — in return for a share of the energy savings. These LED lamps use only 5.3 W and have a life of 48 000 h, so there are considerable maintenance savings in the long term. Organisations wanting to keep all the cost savings can buy TL403GU-D lamps for £12 (plus VAT). The saving on energy bills that can be expected is about 90%

CP Electronics, lighting control

Wireless lighting-control technology from CP Electronics enables fully featured and cost-effective lighting controls to be installed with minimum disruption. The An-10 range delivers all the control functions that would be expected of a hard-wired system — including presence/absence detection, maintained illuminance, dimming (DSI/DALI digital and 1 to 10 V analogue) and scene setting.

Most businesses in the UK are seeking ways of saving money as the economic climate continues to be challenging. One of the most effective methods of achieving this is to reduce energy consumption, which will not only cut operating costs but also keep carbon emissions down. A good way to manage energy spend is to examine the efficiency of lighting. Simple measures can make significant savings in terms of energy wasted, and many technologies are easily retrofitted. For those seeking ways of achieving more energy-efficient premises, installing new lighting and lighting controls provides a good opportunity while giving a rapid return on investment. When looking at energy saving, the focus can often be on heating and ventilation, and lighting may not always be front of mind. Replacing existing lamps and light fittings can, however, make a significant difference to the running costs of a building. Lighting technology is constantly changing with new developments offering increased benefits for reducing energy wastage in buildings such as schools, hospitals, offices and warehouses. Specifiers can work with manufacturers and specialist distributors to identify what is best for their individual application. It is estimated that energy consumption accounts for up to 88% of lighting costs,  so an evaluation of the existing lighting installation to seek improvements can be  a very worthwhile exercise. One of the best ways of saving energy on lighting is to switch to the latest generation of T5 fluorescent tubes that run on high-frequency electronic ballasts as opposed to conventional electromagnetically ballasted products. Normally, this change would involve replacing the luminaires as well as the lamps themselves, but recent developments mean this is not necessary. A good solution is to use plug-in ballasts which can be fitted directly onto the end of T5 tubes with a small extension piece at the other to simultaneously provide the appropriate ballast and increased tube length to enable operation with existing fittings. This will also avoid the inconvenience and disruption of installing new luminaires and result in energy savings of 25 to 56%, depending on the fittings being converted. Another simple, yet effective technique is to change 50 and 35 W halogen dichroic lamps to 5 W LED alternatives, which can reduce energy consumption by up to 90%. Another major benefit is that LED lamps will normally last up to 25 times longer to give a life of 30 000 to 50 000 h compared to 2000 h of use. This means the cost of LED retrofit lamps will be repaid within 12 months based on energy savings alone. Maintenance costs are also significantly reduced over the product life. For applications using SON or metal-halide sources such as warehouse, car park and amenity lighting, selecting long-life, energy-saving induction lamps can offer a number of advantages. In such applications installed fittings are often difficult to reach, and replacement can cause disruption of normal operations. The latest generation of induction lamps will provide energy savings of up to 60% and a product life of up to 100 000 h, or 11 years of continuous operation. Although the initial product cost of induction lamps is higher, the immediate energy saving and ongoing reduction in maintenance costs gives induction lighting distinct advantages when compared to the costs associated with metal-halide and fluorescent alternatives. These can be enhanced further in low-occupancy areas by switching them using presence detectors. For an application where changing traditional SON or metal-halide lighting systems is not an option, there are technologies to assist in cutting out wastage associated with lighting loads. Power optimisation units are available that fit between the electricity supply and the lighting load. A combination of voltage optimisation, power-factor correction and harmonic filtration reduces energy consumption by preventing wastage. These single-phase units sit in line, either at the distribution board or applied to individual circuits to constantly monitor load, while regulating the supply voltage to the optimum. By introducing digital capacitance to the inductive load created by lamps, it is possible to solve the poor power-factor issue often found in lighting circuits and improve it to be as close to the ideal as possible. The additional filtration of all bad harmonics and removal of harmful spikes combine to give substantial savings. An automatic bypass ensures that power continues to the lamps should any failure occur or if the power environment changes from that set at commissioning. Technology is changing and improving at an incredibly fast pace and with the rapid development of LED lighting solutions, wasted energy is now very much regarded as a design flaw in buildings.  Those selecting equipment for projects need to consider not just the lighting effects they are looking to create, but are now having to take into account the wider picture of energy consumption and overall lifecycle. This concept is also being driven by legislation relating to the reduction of carbon-dioxide emissions and also issues of sustainability. As environmental awareness grows, saving energy and, in turn, reducing annual energy expenditure and carbon emissions needs careful consideration. Drawing upon the available industry expertise and the latest products and techniques will ultimately lead to the right solution being found for lighting applications.  Steve Kearney is business manager for the specialist products division of Newey & Eyre.

Rapidly evolving lighting technology means that replacing or upgrading lighting systems can be relied on to achieve significant energy savings and rapid paybacks — explains Steve Kearney.
