I bought an LED bulb today for my frequently used reading lamp. It's
rated at equivalent to 40 watts and to last 46 years. That's about ten

I was just talking to our electrician about those, he's been selling a lot
of LED lighting lately and the only bug so far is failures apparently being
caused by dirty power so to speak--spikes and surges and noise. He's
looking at selling whole-house power conditioners as a result. I expect to
replace our CFLs with LED within a couple of years once the price is more
reasonable.

Hmm,
Few of them burnt out on me after couple years. Just like CFLs.
Lasting 46 years is a myth to me.

I was wondering about that but had not looked up the comparison.
I don't know a lot about electronics but do know that LED's need direct

I would worry about the color too. I had bought a couple of CFL's that
put out such white light that I could not use them indoors and had to

Good news is I understand that new labels are being phased in which will
explicitly state color temp so once you find a color temp you like you
can stick with it.

http://www.ftc.gov/opa/2010/06/lightbulbs.shtm

Bad news is it does not require CRI but I have been able to find that
info for major brands at least online if not on the packaging.
Unfortunately many CFLs still have crappy CRI...

CFL lamps also require dc, they rectify the AC powerline ti dc, and
then run a high-frequency dc - ac converter tolight the lamp tube
itself. There is a large step-up in voltage needed to strike the
initial arc thru the tube, and the reduction in mercury reduces trhe
pressure in the tube until it heats up a little. Regular tubular
fluorescents contain appreciably more mercury than the cfl's do
because the arc lengthis mujch longer and the diameter of the tube is
much larger.

Like a lot of older electrical/electronic hardware, such bulbs are quite
tolerant of poor quality electrical supply. Newer electronic gear--not so
much. But the point is CFLs and LEDs burn a small fraction of the power of
incandescent bulbs, and in case it's escaped your attention burning fossil
fuels has some notable drawbacks including cost and pollution.

Leave it to a bargain-basement ideologue to miss the point. If you want to
pay more for your electricity, go on using incandescent bulbs. We slashed
our power bill by using CFLs with no drawbacks I can see, and I'll be happy
to try LEDs when the price is right. You can go on burning kerosene or
whatever it is you do, and don't forget to check under your bed for liberals

I've had a few that died way before the advertised date, and others that
have gone on happily for years and years, so it's maybe a factory quality
control issue rather than the design itself. But they sure cut our power
bill. I'll try LEDs when I figure the price is right, and go from there
based on what I find.

It sounds great, and I will keep it in mind, but $60/tube for a 4 ft
fixture that likely needs 2 tubes to work well enough? At 1/3 the price
I'll consider a few replacements, but I guess that'll be a few years off

I did pay $40 for a 3-light LED undercabinet light. At 1.5 W/LED, I can

I was wondering about that but had not looked up the comparison.
I don't know a lot about electronics but do know that LED's need direct
current so part of the extra energy may be in the AC/DC conversion.

I would worry about the color too. I had bought a couple of CFL's that
put out such white light that I could not use them indoors and had to
consign them to the front porch.

CFL lamps also require dc, they rectify the AC powerline ti dc, and
then run a high-frequency dc - ac converter tolight the lamp tube
itself. There is a large step-up in voltage needed to strike the
initial arc thru the tube, and the reduction in mercury reduces trhe
pressure in the tube until it heats up a little. Regular tubular
fluorescents contain appreciably more mercury than the cfl's do
because the arc lengthis mujch longer and the diameter of the tube is
much larger.

Did not know that. I do recall someone posting a diagram or picture of
internal electronics for a cfl and there was a lot of stuff in there.
Surprising that they can make them so cheap.

Interesting that the stated power consumption for this bulb is
actually HIGHER that for a 40W equivalent CFL...

A lot of light being wasted in a filter to improve the color?

mercury is what provides the initial ions for current to flow across the
tube. it helps establish the arc.

I took apart a CFL and it only had two transistors,a tiny transformer,a
couple of electrolytic caps,2 diodes and some chip caps. It rectifies and
DOUBLES the input voltage,then converts to HF AC.

I have a 50,000 watt liberal finder, which I activate before
bedtime.

I, and many others of my age, have played with mercury as a kid in the
1940s.
Rub it on a coin and it shined it up.
I'm not sure, but we might have even tasted it.
I remember busting the long florescent bulbs.
There is nothing wrong with me now.


Me too. Many times. I think that my first few Gilbert chemistry sets
even contained a small vial of mercury. I also played closely with a
"nuclear energy" set as a young teenager that included several sources
of alpha, beta, and gamma emitters. I also probably fried my feet to a
crisp in the shoe store fluoroscopes in the early 1950s.


I'm in my mid-60s with no evidence of radiation damage or mercury
poisioning.

This is not to say that mercury and ionizing radiation are not
dangerous, or that what we did is safe. But it seems that the current
hyperventilation over avoiding mercury levels that are only a small
fraction of what we experienced might be an over-reaction.
