I have purchased some LED bulbs as replacements but they really are not bright enough unless you get high powered ones that get really hot and are very directional.

I am pleased to see this solution and hope to see them for sale soon!]]>Sep 18th 2009 12:57AMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/

Also ESL to me seems like old CRT technology with a shotgun approach, rather than a scanning electron beam.
I think that I will buy a bunch of incandescent bulbs and stockpile them so that I have a supply of them long after they are no longer made. Something to tide me over until better technology comes along cheaper...

I think that LED's will get better over time and will probably win out, I just don't think that the full spectrum of available LED colors is being used in bulb production, the current manufacturers seem to be using the Blue/Yellow filtered "White" LED's and they do get more blue over time because the yellow filter breaks down. Why not take the RGB approach and add in the other colors that are required to make a truer white, because every LED bulb that I have ever seen uses an array of LED's... Even throw in some IR and UV LED's to complete the sun like spectrum...

That's exactly what I thought. It's a monochrome CRT with a random spray. I suppose they could make them any color depending on the phosphors they use on the surface. They must dim over time as the phosphors wear out just like CRT raster burn.

White LEDs actually use 3 different LEDs internally so that it produces red, green and blue in balanced amounts, so that you get a white light in the end. You get white because your eyes fool you into believing it's white. But actually, should you send your white LED light through a prism, you'd end up with only 3 stripes of color, one red, one green and one blue.
Do it with natural sun light or incandescent bulbs, and you end up with a rainbow because in that case most of the visible light frequencies are there.

So, the issue with the LEDs changing color over time comes from the fact that the components for the red, green and blue emitters don't have the same lifespans; LEDs lose emitting power over time, but the blue one is the most sturdy one, so after time red and green diminish compared to the blue one, and that's what gives the blue tint.

I didn't think of that before, but it seems to me it's a huge drawback.]]>Sep 18th 2009 3:54AMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:13PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:17PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:46PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.vu1.com/faq/faq.htm]]>Sep 17th 2009 5:18PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 18th 2009 8:32PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:44PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:45PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 8:45PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 8:53PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:46PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/Sep 17th 2009 5:59PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/
Incandescents are not an "electron stimulated luminescent" light source. Strictly speaking, neither are LEDs (although white LEDs usually have phosphors these days, making them so). Incandescent lights take advantage of the fact that a very hot substance will emit electromagnetic energy (look up "blackbody radiation"). If it is hot enough, some of the energy will be in the form of visible light. Unfortunately, much of the energy will be in the form of infrared (heat).

I think this is a great product, if for no other reason than to keep LED and CFL manufacturers on their toes.]]>Sep 17th 2009 8:26PMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/but still a simple cathode ray tube

In that case, it's better to diffuse the electronic beam, as it gives a more uniform light.

In might even be the gas inside the bulb that lights up, not some phosphorous compound on the internal surface of the bulb. That'd be consistent with the fact they're looking into making those in other formats.]]>Sep 18th 2009 3:59AMhttp://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/http://www.engadget.com/2009/09/17/vu1-corporation-sees-bright-future-for-esl-light-bulbs/

This ESL whatever is over hyped. Do you know your average incandescent light bulb is about 4% efficient. ESL would be 16% while LEDs your looking at up to 30% and 50% for OLEDs. ESL is inferior in both efficient and price; what a waste of time. LEDs and OLEDs have no mercury either. These technology have relatively speaking just started to emerge; no wonder not all the associated issues are resolved them such as light quality. The long term solution is both LEDs and OLEDs. This pathetic ESL is nothing but a marketing scam. LED deserves much more respect. And that stupid non sense about heat dissipation in regards to LEDs is completely exaggerated at a 10:1 ratio. You don't need the amount of dissipation that they are showing for LED flood lights; of course you do if you use 1st generation LEDs.
