isn't running those at 40w is what cool people on here do with their diy's ?
250 w [apparently] is a good efficiency so the Panda guy just wss telling you what he thought you wanted to hear
when in fact you probabaly should have wanted to hear they were run @ 40 w
but if they were supposed to be some othre cob brand and ended up epi's instead of cree's well that may not be great
but i understood from emails that the panda guy could make whatever chips you wanted..
seems like a pretty good light/price for a from china..that is if he will put decent cobs in em
he first told me he ran em at 100 w each cob..then said ..well i can run them at 50w
But the people from this forum make darn good looking/spec'd cob units..and the prices seem in line with the hina guy so maybe
companies from here[RIU] are the best shot
Yeah of course "if you ask them" they can (allegedly) make them with some actual, real CREE COBs...needless to say it would sure increase the price massively. And many of those companies are so shady I wouldn't even trust them if they say they put in "authentic" CREEs.
If the company would be credible they would list in plain words WHAT COBs they're using and they also would state the exact numbers of power draw. (Of course, it's not necessarily BAD if they run a 138W CREE COB at, say, 40W or 50W...many do that). They could even run them at 40W and then explain WHY this is done (because it's more efficient etc.) rather than using "big numbers" for advertising. And if a company is already so shady to begin with...well you do the math.
(And by the way, I don't think anyone who now knows a little about COBs would prefer THOSE cobs which are run at maximum, like 100W or more. It means heat, less efficiency, less life-span, I mean we all know that)

Well, yup, EXACTLY. Because, you know, a 600W grow light "sounds better" than a 250W light
And by the way, it's really a shame because otherwise those panda lights *look* nice and even that veg switch to deactive a bunch of lights is not bad. Had they actual, genuine CREEs this would actually be some nice lights I think.
