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.

Hate the twisty bulbs? ESLs coming soon
This product just got UL approval, expect it to show up for retail sales soon. Whats 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.
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.
The LEDs don’t consume 100 watts of energy, they emit the equivalent amount of light at less power....................
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.
And to think that light bulbs used to be given out free........
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
One of the reasons we voted for you last fall was to repeal this damned ban.
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.
The piece said these bulbs don’t.
That was my point.
I’d be interested in the actual wattage of one of these “100 watt equivalent” LEDs.
ESL aka the TV Bulb.
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.
Would the store have to be evacuated & Hazmat called.
Oh, I also need a 3 or 5 gallon flush toilet. Where do I get one of those "illegally".
They can stick 'em where the lightbulb don't shine.
The real problem is that most people don't know what a "watt" is, and wouldn't know one from a hole in the ground -- it's just a word to them. All they know is: "It's as bright as a 100-watt incandescent bulb would be".
Ignorance is really annoying (to me as an engineer), but comprehensible in this circumstance. After all, how many people who compare engines' displacement (in cubic inches or cubic centimeters or liters) actually know how big that volume is, or even what "displacement" is, for that matter? If you tell them, "Well it's the square of the bore, times the stroke length, times the number of cylinders, times pi over 4", they glaze over. Instead you say, "It's about like that 351 engine that Joe has in his pickup", they understand that, even though they have no idea what 351cu-in looks like.
That technology appeared interesting as well.
But, would it have the same eerie light effect that the CFL’s do?
Same functional premise - the electrons emitted cause a coating in the inside of the glass to glow.
If/when these are as good as promised (and I’m eager to have LEDs for landscape lighting - malibu and MR-16 projectors - that is on for a lot of hours every day) market demand will take care of things, not bans.
But you know that greenie socialists will pretend that their bans caused this to be developed.
I replaced one hard-to-get-at bulb at my parent's house with an LED bulb some time ago. So far, it's working great. I'm not expecting to need to replace it ever again. And, if the new bulb saves my Dad from teetering on top of a ladder, perched on a chair, perched on a stack of phone books, because he "doesn't want to be a bother and call me to change it" ..... then frankly I don't care what it costs.
But, I'd say that, at 20 bucks or so a pop, they're not yet ready for prime-time, quite yet. Hopefully in a few years.
Like explaining apartment buildings to people who have only ever seen mud huts...
“It’s like... a bunch of huts stacked on top of one another.”
5K volts are generated. The claims are that there are no X-Rays or EM interference generated.
I don't see how the light quality could be 'better' than CFLs, since both use phosphor stimulation to generate visible light. It all depends on the phosphor mix used.
Watching the lumen output of LED flashlights grow and grow over the last few years, my money is still on an affordable LED bulb coming out one day.
Here’s the cite to the bill introduced by Senator Enzi of Wyoming.
Thanks, that’s what I figured. Will be interested to see how much EMI they emit. For all their other sins, the CFLs are reasonably clean.
odd... a quick search shows an LED bulb (60 watt replacement) for $26
looks like someone is trying to cover for their twisty, chinese made, bulbs
my point being 60 watt bulbs would be more normal home usage then 100 watt bulbs... and 60 watt bulbs have been available and don’t cost $50
Let us know what happens!
It is whiter in color temperature than we are used to from incandescents but runs COLD and is easily dimmed.
As LEDs are available in many colors, a simple mixing of colors could easily be made to reproduce the color temperature to which we have grown accustomed.
It is a testament to the corruption in the Government/Green movement that CFLs were ever offered as a lower energy solution to our current bulbs. Just one of many fronts where we are pawns in the Progressive, Green, Socialist, Marxist plot to destroy everything which made the USA more successful than any other country in the world.
“So far, it’s working great. I’m not expecting to need to replace it ever again.”
Don’t be too sure. Two years ago I bought a 5 watt LED spotlight at Walmart for my front porch. It had a large cluster of LED’s. Since LED’s are are low voltage, the light also contained electronic circuitry to to step down the power from 110 volts AC to to low voltage DC. The circuitry gradually failed within months, one LED segment at a time. So, even though the LED’s may be touted to last a long time, the power supply may not. Great Chinese product, huh?
I seem to recall that Tesla used electroluminescence for stage lighting with huge panels unconnected by wires.
That was in 1905.
Saw the LED flood lights at Lowes yesterday going for 49.00.
I believe you can still get real toilets in Canada. They apparently realize that they (like 90% of the US) have no water shortage.
So do CRT based TV sets (and computer monitors). I haven't noticed anybody growing green antlers from exposure to those.
If the ban takes effect, can we buy them from other countries?
Oh, I also need a 3 or 5 gallon flush toilet. Where do I get one of those “illegally”
Yes, but customs will stop them if they find them.
5 gallon toilet? Canada, or craigslist.
Phosphor spread out over a larger area yields a more "diffuse" multipoint source, thus less "glare". VERY high output LED's are worse than CFL's about "glare". The more closely the source approximates a "single point source" the worse the glare.
But you're right that the overall spectral output should be the same.
I have been stockpiling incandescent bulbs for a while now. Got enough to last me for another 30 years.
Already being done. Currently available is a "bulb" with "white" LED's combined with yellow LED's to yield a "warm white" output.
The piece said these bulbs dont.
Then they are the first cathode ray tubes in history to not produce extraneous radiation. How convenient!
