Has anyone tried them? How is the light output compared to the mercury laden CFL's? I'd like to put them in "canned" lights but would like to hear other's experiences before dropping $9/led "bulb".
I will use them outdoors, for Christmas tree lights and flashlights, etc. They are just not bright enough to light a room adequately. So am stocking up on the incandescents!
Thanks lilypad. That has been my experience to date too but I came across some "dimmable" led lights that look like they should work in can lights. I was just hoping perhaps someone on the forum had already tried them and had a review.

If you have a solid state dimmer, you may have trouble getting it to dim the LED lights. Unless the load going through the dimmer is over about 40W, some or most solid-state dimmers will not function properly. It can be tricky to get 40W worth of LED's into one room...

Are you saying that the LEDs load is too small for the dimmer to detect soi that even if an LED is advertised as "dimmable" it is really not the case unless the load on the entire circuit is enough?

Forgive me but I'm not an electrician.
Yes, you hit it on the head (albeit with a very large hammer). Lutron manufactures a line of dimmers specifically for LED's and CFL's for this very reason.
We just installed CF dimmable bulbs in the bedroom ceiling light fixture. They provide more light when full on but only dim about 50% instead of nearly off.

Good to know.
Looks like I'll need to ask the electrician to install these specifically if it is not already too late. My dimmers are located in a multi-light switch box and not a stand alone.
I'm just trying to plan ahead so when this smart grid mess hits I don't have to retroactively fit then and maybe can be ready to go offgrid anyway. It seems that using LEDs where possible would decrease the required electrical load.

GregW, is that using a standard dimmer or the Lutron to which one jimbournsey referred?

Some dimmers work quite well with low power loads, I know some of Lutrons Dimmers with neutral wires are rated for loads of 10w min.
Check the specs for the brands of dimmers you own. SOME DIMMERS MAY
BE UNSAFE WITH CFL OR L.E.D. LIGHTING.
With that being said, some of the CREE L.E.D. lighting is very good.

I have yet to find a dimmable CFL bulb that lasts anywhere near the rated life, I have used several that dim quite low but then burned out quickly.
