DOE Lighting for Tomorrow
Lots of great energy stuff up at the DOE site — including Solid-State Lighting: Research Highlights which has their award winners for solid state lighting last year. I’ve tried some of the inexpensive commercially available LEDs and they suck. I’m going ty try out one of these more expensive can replacements
I’ve definitely wondered how good the LED floods/spots are. Please post an update when you get around to trying out the can replacements.
