personally i wouldnt buy from a site that claims to have branches in the U.S but cannot fix even the simplest of grammatical errors on their home page...Description: "though the electronic frequency as light source, and without filament..."
It looks like they're using a type of fluorescent (with a life of 100K hours!?), but not much info from their site:

Thanks! Can't wait 2 hear about your results. Would you recommend the 2700 or the 6500?[Just want to clarify some confusion on these lights.These are Not LED's. They are a electrodless fluorescent light. There are a few options for these. First there are three different color spectrums available. your standard 2700K and 6500K and then there is a 3600K bulb. The 3600K bulb is the one that you are refering to. It is also a purple voilet coloured light very simular to the color of LED grow lights. To achieve this color, they have to coat the bulb with special phosphours. The problem is that the coating is too thick and blocks out most of the light. the 400 watt specs is 16000 Lumins alittle more than a 250 watt CFL. The 2700 and 6500K bulb is a much better choice as the true advantage of this technology is realized. The light output of a 6500K is 36000 lumins. I am in the process of testing these bulbs and will confirm which bulb color is best. Please check out www.enviro-techlighting.com for more info. Their pricing is much better. I paid $485 for a 400 watt. I will post pictures soon.
Why would how bright it is matter? Visual brightness and plant absorption spectrums are vastly different.doesnt look very bright in the pic

I think Ryan is right. What is good for the plants, is not really the same as what is good for our eyes.
These bulbs are interesting, I'd like to try the 400W model, I might spend to test it out $600. The only model available now is the 300W though from what i saw on ebay
I'd like to try to 400W version. Running these lights are cool temperatures, basically eliminates any need for an airconditioner, which simplified things so much along with slashing electricity.I bet this light sucks for OUR purposes at least.
You should try it out and let everyone know the real scoop.
do you have a source for the 400W?I'm planning to try the 400w. Because of my narrow tall space (2.5'w x 5'd x 7't) I'm hoping to use a light mover to pass the hanging bulb within inches of the plants in a vertical grow. The lack of heat is appealing. I don't want to vent. Less energy is also appealing. Trying to decide which bulb-(kelvin) 2 try since I will be primarily budding plants under this light? Likely will use good led 4 clones.

also, i want to use vertical also, but they seem to come with a built in hood, i bet would could remove it however.
sure enough, this looks good.There's a Canadian supplier @ www.enviro-techlighting.com -- the light appears w/o hood in pics, only wires to ballast.
looks like a choice, wasn't someone else testing these? would love to hear some feedback, i am considering seriously buying.Like the Par Max CFL’s, the Par Max EFDL’s come in 2700 and 6400 Kelvin colour for maximum PAR light spectrum that plants use.
