Ed: You think the light has a much greater effect? How has the power consumption changed? Interesting project... Is the light a really deep blue? I can see the blue fringe in the photo that you took. The LED color issue is one that people have been working on for years. A white light LED technology would make a man very very rich...

Sometimes I see the blue headlights on high-performance sportscars and they irritate my eyes (mostly while driving). I'm not so sure that's the effect I'd want my lighting system to have on a motorist....

General: Do you all think that there's a good market for such specialized devices? This is the sort of business opportunity that interests me as I finish my engineering degree...
