More than four hundred 400W mercury discharge luminaires at Premier Decorations’ warehouse in Wrexham have gone the way of the dodo, replaced by Luxonic’s Aislelux louvre fittings, each equipped with pairs of Osram 80W high output T5 fluorescent tubes.
You don’t have to be a mathematical genius to work out the energy savings involved (see box, left). Premier imports Christmas, summer and Halloween decorations, and was concerned that lighting its warehouse was one of its largest overhead costs.
Tim Clark, Luxonic’s lighting design engineer says: ‘We chose triphosphor Lumilux T5 HO Constant fluorescent tubes and Quicktronic control gear. The Lumilux tubes give stability at high and low temperatures and constant output throughout their 20,000-hour lifetime.
‘The control gear means we can dim the tubes down to 1 per cent light output. We combined the tubes and control gear with integral presence detectors that allow the fittings to dim down when the room is unoccupied.’
The new louvred fittings are not only more electrically efficient, they are specifically designed for use with racking systems. Also, the colour of the light has been improved, enhancing the working environment.
