Regarding the garage door opener interference, remember that LED bulbs have a
switchmode power converter in the base, see for example
http://www.nxp.com/documents/data_sheet/SSL21082T.pdf
which gives the typical conversion frequency for that particular chip as 100
kHz.

I just replaced 3 Dusk-Dawn Dimable ouside fixtures from 100w incandescent to
the 100w cree LED's. I'm only monitoring my Whole home Current, but it looks
like it's saved about 1A draw in the overnight hours. The LED's are much
brighter than the Incadecents were.
Interestingly enough, I put them in my garage door opener, and the remotes
stopped working. Took the bulbs back out and it's fine. Must be some sort of
interference with the DC Power supply that close to the antenna.
I've also changed the 5 Flourescent light fixtures in my garage from 2 bulb 40w
tubes to just 1 18w LED Tube. They provide more light than the old bulbs.
Last few bulbs I paid $12 each for off Ebay.
At Home Depot look for the 'contractor discount' It's on some bulbs. I
believe that if you buy 5 of the same SKU you get $5 off per bulb. I think the
60w Crees fell into that last time I was there.

The flood that failed on me was an "ecosmart" brand from Home Depot, FYI.
I was just there today, and they had some on sale for under $5 a bulb. They
also had some new "100W equivalent" ones that would probably be great for a
garage, shop or someplace else that needs a lot of light and maybe isn't
heated, which was always a problem for CFLs.
