[Greenbuilding] compact fluorescent bulbs

[David Bergman]

Jason,

Did you mean electronic ballasts in your note below?

Your LED products are looking like a great step forward, though I'm 
still looking for higher output recessed cans, with light spread like 
incandescents. I recently went through spec'ing fixtures for a 
residential project in which we are using almost no incandescents 
(only a few track heads). I had hoped to use LED highhats, but 
couldn't find any that did the job well enough, so we "settled" for 
CFL. And the disappointments there were (A) the aperture size and (B) 
no dimming without major expense.

Are your highhats on display in any NYC showrooms?
