Sample text

Finelite HPR LED troffers only lose 10% of initial lumens at a rated life of 100,000 hours. Acuity Brands’ nLight system under-drives the drivers about the first half of rated life and then increases drive current as the LEDs become less bright. Photocontrol systems could be used. Digital clock chips could be included to slowly increase drive current over time. In general, L70 is okay for exterior LED fixtures, because HPS and MH can lose that much light. However, it would be good to go to L90 (rated life being when 10% of initial lumens are lost) for interior LED fixtures.

This way we do not have to measure, order, receive, and install any kits, so we can work faster with fewer potential headaches. • As a lamp supplier, our sales volume stays high and we sell these lamps for spot or group relamping. • A retrofit contractor or an ESCO is not always necessary. • The best rebates are with these lamps. • The new lighting is very similar to the old lighting, so nobody should complain. Regarding the last bullet, if the old lighting was crappy, the new lighting can still be crappy.

If anybody does not like the new lighting after two or three weeks, please let me know. It is also important for the installers to finish rooms before the regular workers come for the next day’s work because having two color tones in one space does not look good. With this protocol, I have not had to change the lighting in even one office back to a warmer CCT. Many lighting designers do not like high CCT fluorescent lamps and usually specify 3000K or 3500K fluorescent in new construction and remodels.
