A 30% saving in energy consumption has been achieved with a 37% increase in lumens at the Defence Logistics Organisation in Andover with new lighting.
The Defence Logistics Organisation’s Building 300 in Andover, Hampshire has gained a new look at a reduced future cost with an energy efficient lighting system.

Building 300 is architecturally attractive with a glass roof and atrium, but the existing lighting installation did not make the most of its features. At almost six years old, up to 25% of the luminaires were no longer giving optimum performance, providing the opportunity for an upgrade and more energy efficient options.

A trial installation was set up by Philips Lighting Solutions, where it was shown that switching from 100 W SDW-T lamps to Master Colour CDM-T 70 W lamps would produce a 30% lower energy consumption, while giving an overall lumen increase of 37%. The use of these lamps will also give a 50% increase in service life, reducing maintenance costs.

Some 200 lamps were installed in the building following the initial trial. Philips supplied all components including lamp, gear and luminaires.
