The LightCommunity

I came across the Philips LightCommunity today.  Its a good place to read up on the latest technology, along with learning how lighting designers are continuing to improve their craft.  Also its a good place to post questions on the community board.

BUG Ratings

What are BUG ratings and why are they important?  I came across an article written by Max Pierson the other week on his blog.  It discusses well the differences between how traditional sources were defined (full cutoff, semi cutoff, etc) and how the new BUG ratings for LED's are determined.  It seems specifiers are often locked into lumen output and watts of a fixture, but when designing the lighting for an outdoor area, there are other factors, such as the BUG rating, that need to be considered when selecting a luminaire.

The DuaLED

Daybrite originally launched the 2x2 DuaLED, which many of you are familiar with, now, using a complete philips solutions, with a promise to maintain backwards compatability with all their parts, this fixture presents the first solution for the architectural troffer in LED that is affordable and easy to maintain when the time comes. Ranging from 2700 lumens up to 4400 lumens, the 2x2 DuaLED is a top performing LED solution and with the addition of the 2x4 version, which tops out at 80 system watts and 7,300 hundred delivered lumens, you can have even more punch and diversity in design than before.   Click on the above photo to learn more!
