I have been closely watching the developement of this industry for the last year or so. Each item I have investigated has been a dissapointment. The replacement lamps for florescent tubes deliver an inconsistant light, just don't look right, and are very expensive. Par 20 and 30 and MR16s were similarly dissappointing.
Streetlights and parking lot lights however are a different matter. The time for these lights is here. Check the website betaled.com for some examples. I haven't got final prices yet but I am watching the City of Los Angeles which has pilot programs looking at different manufacturers.
It seem clear that even the leds that claim domestic manufactering are simply assembled here and most of the products rely on Cree to supply them with product. Jack Miller jack miller
