Thorn has developed a high-lumen output LED version of its already successful Cruz downlight – an important step which, according to the company’s product manager, Hans-Georg Schmidt, will completely change people’s thinking about general lighting.
The Cruz LED uses active cooling technology to outperform compact fluorescent (CFL) downlights in terms of energy efficiency and quality of light from a third smaller aperture. It delivers 2,000 lumens, with only 6% optical losses, in either warm white (3000K, 51 lm/W) or cool white (4000K, 55 lm/watt), equating to a 2 x 26W CFL downlight. The use of a remote yellow phosphor lens within a sophisticated optic limits glare (UGR < 19), with consistent colour performance (Ra ?80).Â
 “What the Cruz LED does”, says Schmidt, “is open up a whole new range of possibilities for commercial and retail lighting. Previously LEDs were mainly used indoors for localised lighting, such as corridors or areas with low ceilings. The new ratings make solid-state lighting a viable alternative for those seeking smaller, more elegant alternatives to compact fluorescent in general spaces.”
