A new lamp technology!
Posted: September 30th, 2009 | Author: Kevan Shaw | Filed under: Blog | 4 Comments »Some of you may have heard of ESL (Electron Stimulated Lighting), a company called Vu1 has been talking about it for a while. At last they have broken cover with this video
Though massively lacking in detail as to quite how it works, what is inside the lamp and what the real output is they are suggesting that they have a product that will be marketable in the USA next year as an R30 replacement for something in the region of $20. This will probably be in the range of 40 to 45 lmW efficiency.
I must say the very brief technology demonstration looks like the workings of a cathode ray tube (CRT), remember them:) If it is, it will still have some colour related issues in making a white light phosphor and there will be issues of radiation emitted from the electron gun, this was solved by heavily lead loaded glass on a CRT that makes these very difficult to recycle to useful recoverable material. Come on Vu1 tell us how these really work and what is going on inside the lamp!

Shall we contact them and ask then to come and show/tell us? Or have you done that already!
Amazing! Not clear for me, how offen you updating your greenpages.pld-a.org.
Thank you
I’d like to see some meat on those bones…
it does look awfully like a CRT (interesting that they mention expertise from Sony and LG), but how the hell do you make a 4ft fluorescent version?
CRI? Colour temperatures? Lifetime? All the usual questions, really.
@ Sharon, I haven’t contacted them but it would be a nice idea to have them come and show us the thing and answer some questions, however Iain’s reputation for savaging the unforthcoming may have preceded us:)
@Jinny, I update as and when I have something interesting to post and the time to do it. I must admit to a bit of a backlog at the moment, hopefully some new stuf in the next couple of days!
