LED bulbs hit 100 watts as federal ban looms

NEW YORK (AP) -- Two leading makers of lighting products are showcasing LED bulbs that are bright enough to replace energy-guzzling 100-watt light bulbs set to disappear from stores in January.

Their demonstrations at the LightFair trade show in Philadelphia this week mean that brighter LED bulbs will likely go on sale next year, but after a government ban takes effect.

The new bulbs will also be expensive -- about $50 each -- so the development may not prevent consumers from hoarding traditional bulbs.

Did you know that there's a 3 page guide on the proper steps to clean up a broken CFC light bulb. 3 pages for crying out loud.

WARNING--WARNING--THREAD HIJACKING IN PROGRESS:

Hate the twisty bulbs? ESL’s coming soon

This product just got UL approval, expect it to show up for retail sales soon. What’s an ESL? Think of it as an unfocused Cathode Ray Tube or CRT. The definition at Wikipedia is: Electron Stimulated Luminescence (ESL) is light produced by accelerated electrons hitting a phosphor (fluorescent) surface in a process known as cathodoluminescence.The light generation process is similar to a cathode ray tube (CRT) but lacks magnetic or electrostatic deflection.

Dumb headline.
If the LED bulbs consumed 100 watts, there’d be no reason to replace 100 watt incandescents.

But... we’ve grown so used to measuring the light output in watts instead of lumens that they had to make the comparison this way.

Attention, House GOP....

One of the reasons we voted for you last fall was to repeal this damned ban.

So repeal the damned ban!

Either Obama or Harry Reid will stop it, but that’s okay, let them take the hit.

At $50.00 for each LED bulb, people may well hoard INCANDESCENT bulbs to sell AFTER January 1, 2012.

[Red Badger]

The LEDs don’t consume 100 watts of energy, they emit the equivalent amount of light at less power....................

[Buckeye McFrog]

That ESL bulb is in essence a mini picture tube from an old-style TV set. Those things throw out a bunch of unwanted radiation in addition to heat and light.

[Hot Tabasco]

And to think that light bulbs used to be given out free........

[manc]

one of a very important handful, I’m still try to get to grips that a Govt has banned these bulbs, what does it matter if my bill is higher and these new bulbs are crap, they don’t last long, expensive and dangerous.

Get rid of the ban.
get rid of Govt health care
overturn this don’t ask don’t tell

I recall reading that a Republican Congressman initiated a bill (in February, I think) to do just that. I'll see if I can find out what happened to it.

The ESL looks promising - at least it doesn’t look like a dairy queen cone ;-)

I’ve noet read a good description of how it works - the conventional approach to making enough of an electron beam to excite phosphors is with several KV of high voltage, and that would seem to imply a potentially noisy (EMI-noisy) switching power supply. Anyone know?

They are useless. All talk no walk.

I'm stockpiling them to use, not to sell.

[muawiyah]

The piece said these bulbs don’t.

[MrB]

That was my point.
I’d be interested in the actual wattage of one of these “100 watt equivalent” LEDs.

[Jack Hydrazine]

ESL aka the TV Bulb.

[albie]

This reminds me, I need to get to Lowes and stock up on incadescents! I’ve got 23 different light bulbs through my house and about a 3 year stockpile so far.

The electrons are unfocused, so according to the maker Vu1 and the UL they don't produce X-Rays. The focused, accelerated electron beam of a CRT does throw off X-Rays. CRT TV tubes use heavily leaded glass to block those X-Rays.
