Remember this one from April 2008

And now after 3 years they are finally on the market and on eBay

I can't say I like the price or the size, but Wow that's an impressive light bulb

wow gets to be 6000 kelvin inside that bulb.  Did it say how much heat comes out of the bulb?  I ask this because at that temperature, if there is surrounding residual heat, say around 3000F, you could dissociate the water molecule and get cheap hydrolysis.

This is from the eBay link.  Operating Temperature -40 to 45°C

powercat,  LED efficiencies have grown by leaps and bounds since 2006.  That article quotes LED efficiency of 70 Lumens per watt which was years ago.  LED's take a leap in efficiency every 6 months or so.  In May of 2011 Cree announced 231 Lumens per watt which far exceeds the efficiency of that plasma lamp.  That was over 6 months ago.  I've got several LED's that do over 200 Lumens per watt.  I've got a flashlight that's no more the 3.5" long by less than 1" diameter that puts out around 600 Lumens.  Ceiling bounce that and it's like a 60 watt light bulb lighting up the room.
