Because of this energy cost savings, the incremental added cost of the LED fixture is typically paid within the initial year of operation. This is in addition to the very significant cost and maintenance savings of never again having to replace a fluorescent tube. With over 50,000 hours of life expectancy, and depending upon the actual operating conditions, the luminaire could be expected to provide superior lighting well into its second decade of operation.
The architecturally designed XTR luminaires, available as 1 ft X 4 ft, 2 ft X 2 ft and 2 ft X 4 ft fixtures, include three light engine cylinders made up of linear arrays of high efficacy LED chips which are fully tested in accordance with LM80 requirements. Superior photometric and thermal management engineering ensures the LEDs will always run at the cool temperatures necessary to achieve their rated long life potential while producing high quality natural light.
Additional features include diffusers which are specifically shaped to be thinner yet stronger and more efficient than simple flat diffusers and drivers with higher power factors (> 0.9). And unlike fluorescents, LED lighting products contain no mercury or other toxic materials, no glass, turn on instantly and are dimmable. With a low profile of only 1.8 inches, the XTR troffer will fit into even the tightest of spaces.
