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.

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!
Thanks Bush/Pelosi for the help!
The claims are that there are no X-Rays or EM interference generated.
It’s a safe bet that “no x-rays or EM interference” really means “it passed the regulatory test for radiated emissions” NOT “there are no EM emissions”.
LED bulbs put out an ugly glare at higher wattages. I’ll stick with the regular incandescents for as long as I can. Last I checked, Arizona Home Depot stores still sell them. Will need to stock up next time I’m there.
We installed LED lights under our kitchen cabinets during a recent mini-renovation. They give off a ‘warm white” light, much better than fluorescent bulbs.
They are not cathod ray tubes. They are not using X-ray to stimulate the phosphors.
I’m running out of room to put my “stockpiles”! lol I might have to build a bigger storage building...........
Vu1’s web site played a little fast and loose with their comparison chart claiming LEDs could not be dimmed (they can, I have one) and also claimed LEDs were not as recyclable as the ESLs. Hmmm, seems the ESL will require, to produce the high voltage needed, quite a bit of silicon based products encased in plastic as would the LEDs.
Also, the color temp comparison of the ESL vs LEDs were slanted by Vu1 and that may be true for CURRENT LED bulbs but both products could easily be produced in a wide range of color temperatures. If that were not the case LED TVs could not work. A bulb constructed with multiple LEDs of mixed colors could easily mimic any color temperature required.
There was also another claim that LEDs were susceptible to high temperatures (actual temp not defined) while the ESLs were not. Given the requirement to have a High Voltage power supply built in I would suspect the silicon based products in the ESL would also have an issue with higher temperatures. In any event it is good to have competing technologies as the CFL is a horrendous choice forced upon us by lawyers (congress) acting as our energy guardians.
“Already being done. Currently available is a “bulb” with “white” LED’s combined with yellow LED’s to yield a “warm white” output. “
Great! Have you seen them yet? I have not but that only means they have not come to a store near me.
I’ve been stockpiling them for years. I currently have enough incandescants to light my house for the next five years. I’d have more but my husband wouldn’t let me rent a storage room to keep the others in.
All I need to know is does it go fast? And how quickly can I get to cruising speed?
