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.

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%

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.

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.

Energy consumption for lighting has been nearly halved at the Royal Military Academy Sandhurst following the installation of Osram’s Lumilux fluorescent tubes in the east and west corridors of the Old College. Lighting levels have increased from 180 to 340 lx.

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.

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.]

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.

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.’

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.

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.

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.

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.

Providing effective lighting from a high mounting position is very demanding on light sources and luminaires. Clive Riddell explains why metal halide is still the best choice for low- and high-bay lighting.

Osram has introduced a range of light sensors to ensure that light is used only when necessary, conserving energy and reducing overhead costs. There are three sensors, High Bay, Duo and Vision. Used as part of a light-management system, these sensors can significantly reduce the energy consumed by lighting within a building.

Carlsberg has achieved a major increase in lighting levels in its 4200 m2 plant at Northampton by installing 350 W metal halide lamps fitted with solid reflectors within existing luminaires. Lighting levels a metre above ground level have been increased from 80 lx to 250 lx. The Uni-Form pulse-start lamps from Venture Lighting have 350 W magnetic as part of a easily installed conversion kit for the previous 250 W lamps

A Delmatic lighting-management system is achieving energy efficiency and a high level of flexibility in a new office development in Reading. The system has helped The Blade achieve a ‘Very Good’ BREEAM rating and offers incoming tenants the freedom to modify the system to suit their needs.

The web of light linking spaces within the restaurant of the new offices of UK law firm Addleshaw Goddard at Milton Gate in London was created using RL 40e ‘stick lights’ from Waldmann Lighting. The lighting design was by Chapman Bathurst.

Prolojik has completed the final phase of a new integrated lighting system for Lloyd’s of London. The work was phased over three years to minimise disruption to occupants. In addition to lighting controllers, Prolojik also supplied the heat-pump and fresh-air controllers. All user local control of M&E services is via combined infra-red controllers.
