I installed two, 60 watt LED bulbs in my loft studio ceiling. They
are
shaped like regular old light bulbs and illuminate in the same,
non-directional pattern. I like them. Plenty of light, doesn't have
any
funny color and I have them controlled by a regular dimmer designed
for
incandescents. No problems dimming them although it doesn't like
controlling only one. Not enough load.
The LEDs may be OK. But the mini fluorescent. More expensive, do
not last
any longer and are toxic waste. Ow many land fills will become
superfund
sites with the bulbs?
My problem with LEDS and CFLs is they do not change color when you dim
them. The warmer colors you get from a dimmed incandescent is the
whole point.
I know they could do this with a color changing LED but at what cost?
If I am happy with a $1.50 lamp that will last almost forever running
at 75% power, why would I want a $50+ LED that uses almost as much
power "dimmed" as it does full bright and may actually fail sooner.
I never noticed that the LED bulbs are not "warmer" color-wise when
dimmed. I guess that's not very important to me. The room just gets
darker.
The whole idea behind these types of bulbs is energy conservation, not
romantic lighting. Replacing one 60 or 75 watt incandescent bulb
with a
LED bulb of equivalent lighting may not be huge, but replacing tens or
hundreds of millions across the country sure is.
Lighting makes up about 13 percent of average residential electricity
consumption. Replacing the old bulbs as they burn out with LED
equivalents makes sense to me. We've slowly been doing that over the
past year or so and also replacing any of those stupid CFL type lights
we have with LED types. The built-in ballast used in CFLs seem to pop
as often or even more so than the incandescent filaments did.
The LED bulbs I bought are made by Cree. They don't cost $50. They
are
$12.95. 800 lumen, dimmable, 25,000 hour life expectancy, 10 year
warranty and consume 9.5 watts.
I bought a few of those Cree bulbs at Home Despot. They seem to be
working well. Haven't noticed any difference in the color of the room
lighting.
I confess I was a bit of a skeptic until I tried one. They work fine,
to me. Proof will be in the pudding in terms of how long they work.
The package I have says it will last 22.8 years at three hours a day
until the bulb burns out. In 22.8 years, I suspect the bulb between my
ears will dim, if not burn out entirely.
I read somewhere...maybe it is a false memory...that you shouldn't put
two of these bulbs in a multi-bulb fixture. But there's nothing on the
packaging that says that.
I'd like to find some "candleabra" LED bulbs. We have a zillion of them
in the house and in our outdoor garage and porch fixtures.
Your 22.8 years has expired.
