I don't have links to all the relevant documents handy,
but 100W, 75W, 60W and 40W are all banned from import or
manufacture in the US (rough service bulbs are
exempt...for now at least). Stores are allowed to sell off
existing stocks and inventory, and many chains stocked up
heavily before the second half (60W/40W) of the light bulb
ban took effect.
I have VERY few incandescents here. I have started
converting our kitchen
(where the lights are on a LOT of the day) to LED. I
couldn't find anything
I liked (some LED fixtures are actually on recall as a fire
hazard) so I
built my own. I made a 10 LED fixture with Cree 1W LEDs
first for our
pantry/laundry room, which had the worst lighting in the
house. (A recessed
fixture too cramped to fit a CFL, and made so it lit a spot
on the floor and
not the room.) I built my own constant current source for
it, and it was
a huge success. So, then I built two retrofits for dual 48"
fluorescent tubes.
These have a string of 20 1 W Cree LEDs and a commercial LED
lighting
power supply. The old magnetic ballast drew 103 W, the new
LED system
shows 21 W, and the lights actually appear brighter than the
fluorescents.
I was worried that the color temperature would be horrible,
the LEDs look
real blue if you look at them, but with the fixture,
diffuser and the
whole room, they look perfectly normal. (Warning, if you
look right
AT the LEDs, you will only be seeing spots for a couple
minutes, they
are blindingly bright.)
