Sexy topic, I know.
I see the eLightBulbs ads all over the place. It’s actually a relatively rare instance where a banner ad got me to click through and actually buy something. They had LED (or was it LCD?) light bulbs with standard bases and apparently the equivalent lumen output of a 25 watt conventional incandescent bulb at a pretty cheap price (around $5 or $6 I think). I bought one, and because it seemed silly to pay shipping for one bulb, bought some halogen spotlights, too.
The LED/LCD bulb worked about as I expected. Aside from techno-geekery, I did sort of have a reason for it. One fixture in a basement storage area is really close to where I’m storing some paints of various sort, and I thought there was a small chance that the heat from even a CFL would reduce the longevity of the paint.
On my wish list:
CFL bulbs (spot-light style) where the dimmability really works smoothly from 100% down to 5% or so, without buzzing or other problems.
Bright CFL bulbs (equivalent in lumen output to 100 watt or so incandescent) where the spiral is not exposed, but rather, surrounded by glass, to reduce the glare and reduce the danger of breakage with parts going all over the place.
LED/LCD bulbs that can do the light output equivalent of a 60 watt incandescent at a reasonable price (no more than $5-10/bulb). (I don’t think these are available yet, but maybe in the next 2-3 years?)
