Decorator spot good for a picture frame.

LEDs have a way to go and the break even point is nowhere to be found at
those prices, yet.

I routinely buy LED lamps.   They have all crapped out early except for the
last 2 I picked up from Wally World.   These have some 18 LEDs arranged in a
paramid inside the globe.   I have put them in two fixtures and they seem to
be the "real deal!"

The CFLs are really, really getting more reliable.    It seems for a time
that I was replacing a CFL about once a week.   But I don't remember
replacing the last one.   (Yeah, just about every interior and several
outdoor fixture has CFLs.

THE problem the makers have is that as they make better products the total
demand goes down!

It's only a matter of a few years before fixtures come with LEDs or CFLs
which are "hard wired" and would be expected to last long enough that you
decide to change out the fixture from boredom before you have to "re-lamp!"

Home Depot's got a house brand "40 watt" equivalent LED lamp
now in hte stores nearby for nineteen somethin dollars.

I just picked one up.

Using the Mark One Eyeball for measurement, it's
a tad dimmer than a 30 watt incandescent. I don't
have the boxes with me, but when I looked in the
store the numbers were something like 3,500 lumens
for the incandescent, 3,200 for the LED.

I emphasize NOT to rely on my memory here, but the
roughly ten percent difference was on the labels.

Anyway, it's the standard incandescent bulb form,
and...

While it's a tad less bright when in a regular base, I
found a perfect use for it.

I placed it in one of the five holders standing out from
a ceiling fan. The lamps are controlled by a dimmer
switch on the wall.

In this application, the LED was (again, per Mark One Eyeball)
every bit as bright as the incandescents. And when dialing
downward, it dimmed fine and was actually a bit brighter
at the lower settings than the incandescents.

My guess [tm] is that the wall switch, even at max, cuts
out a bit of the voltage/current/waveform, so that the
actual passthrough is, say, 95 percent. The LED gives
out 95 percent of the "full" light, while the incandescents
give out 90 percent...

Anyway, for many uses this is a good actor. At the equivalent
of 35 watts, it's fine for many locations. And since the LED
comes "right up" and is much _less_ sensitive to cold temperatures,
it would be good for outdoor use with a motion detecter or
a garage type on/off. The long life would be an extra plus...

Don't automatically assume that every LED bulb is dimmable.  As always, read the
label before you invest.
