I wrote about a company called Vu1 a while ago – Vu1 has the ESL technology lamp, which stands for Electron-Stimulated Luminescence. It’s an interesting concept that tries to replace the idea of the light bulb into something completely different yet stunningly similar.
Reader Chinco Erai posted about a documentary video in the comments recently – it was an excellent look at the ESL technology – check it out!
They didn’t mention lamp life in this video at all, how long can one expect a bulb to last?
Nick – I think it’s about 6000 hours. Not nearly enough, but I am still unclear at why it’s such a low number. I’m still trying to figure that out.
If this lives up to its full potential, this could be, how do they put it, a disruptive technology? Well, a game changer anyway. If it does everything they are claiming, just the novelty of it producing light from a glowing bulb will be enough to pique people’s curiosity and with that going for it, it will sell itself. I wish this company the best of luck. It’s always a wonderful thing to witness a great idea coming to fruition. Please keep following this company for us. Thanks, Jim.
CFL in the movie has really poor color rendering qualities, although today we have quite a range to choose from: Ra 60 to 90 per cent. Besides there are different color temperatures so a user now does have options (2700K, 3000K 4000K), even if we speek about E27 socket.
But interesting video! Jim, thanx for keeping us updated on what’s going on!
I just came across this. I am very interested in lighting issues, and this seems like it could hold promise. It looks like the spectral output is superior to fluorescent or LED lights. I do wonder if there are any emissions such as electron/beta radiation that should be taken into consideration. Anyway, I will be looking into further. Thanks.
