I don't know about them. But 5 minutes dissecting their web site and I can tell it's a bunch of crap Chinese knock off using multiple 5w diodes to make them "look" like COBs. They're not COB lights and no more effective at flowering than Chinese knock off panels at half that price. This is just another Chinese diode based piece of crap with ridiculous claims and outright lies in their advertising.
The site is a scam trying to sell old technology at premium prices. I personally don't care about warranty and if you're buying off a site/company like the one linked you cannot expect any sort of service or warranty. They'll use every trick in the book to avoid paying out warranty work and cease to exist within 1-2 years so their "3 year" warranties aren't worth the paper used to pack their shitty lights.
It says they are 5w diodes right on his site. That company is a scam, but hey it's your money, chau, unsubbed, waste of time, asta la vista...
I'm sorry but I don't know anything about lights, to me diodes could be what you build a cob with and I wouldnt know any better... So there are no diodes in a cob? Then if you use cree diodes then it's not a cob you are building?
First, it's your money. Do whatever you want. It won't be the end of the world. But, there are many people who followed the "come on" of companies like MarsHydro (or the expensive rebrands like Kind and Lush) and they got less light for their money.
the cob builders are all on this site, theres like 4 companies on here. maybe more.
I think you were given some names in your General thread. Tasty, Johnson, Area-51. Pacific, Amare, Go Green.
I'm looking for led because I tried cfls and the heat was too high for my environment in the summer. Also because I am on a 15 amp circuit and there are oter things on it. I don't want to load the circuit as the electricity here is aluminium wiring. S. i need less heat than cfls and less than amps of pull. I figured led was the answer.
Yeah... There's a few I havnt checked yet though...
LED is for you. But, I would stick with the names given. If you buy the generic epi-whatever stuff you can easily find yourself using 50-60w/sq ft. At that point T5HO or CMH (for taller spaces) is a better value. I.e., less electricity, less heat, more light.
A light draws n watts from the wall. Less efficient epi-whatever lights can cover n sq ft at 50w/sq ft. That's their efficiency. It actually may be more. One person here is considering running over 70. I was looking at a grow last night that was considered "wall of fame" material at 90.
If your goal is to reduce power consumption and heat, more could definitely hurt. Especially when you have run *a lot* more like the epi-whatever lights. In that case, T5HO produces more light, less heat for short grows. CMH for tall.
Hey man if you want to teach, I'm down to learn...A light draws n watts from the wall. Less efficient epi-whatever lights can cover n sq ft at 50w/sq ft. That's their efficiency. It actually may be more. One person here is considering running over 70. I was looking at a grow last night that was considered "wall of fame" material at 90.
The DIY cob guys are doing 25'ish w/sq ft. The Area 51 is spec'ed for 26, if I recall.

If you get into the COBs described here, more doesn't hurt as much. Going from 26w/sq ft to a gargantuan 35 is still less than what MarsHydro specs their lights at (yet seemsto have to run them at 2 to 3x more. That's probably what you would encounter with that cob-like object you were looking at.).
So, it's kind of relative. You can definitely get away with "more" using efficient LED without nearly as much heat as you would have with epi-whatever lights.
