    Id go with a 185 1400b or 185-36a. Better match for the 36v cobs

    The drivers have built in safety features and your heatsinks are appropriately sized and passive so no fans to break. I had a customer who just lost 3 out of 8 clu058 as they were being run hard on active coolers and the power strip feeding the fans clicked off. That cant happen with chips at 50w on passives

    Its been many moons since I posted here in this thread, or in the LED section at all, for that matter. This is mainly due to me moving on to using multiple CMH 315's in my garden nowadays. That being said, I have been very eager to try out some COB lighting, as well. So I added a nice, new, Tasty T22-4000/80 COB light to one of my 3x3 tents. I'm very pleased with the results so far.

    All my leds are forced air cooling and passive cooling will be top of the list for replacements someday. Until then my slightly dated COBs and more dated a51s will have to do!

    That is unfortunate but really just poor design, isn't it? And i say that in the most practical way, not trying to be pedantic or derogatory either....
    A simple way would be run a $3 solid state relay that shuts the mains when the fan loses power.
    Even easier is to run a re-settable thermal switch or a thermocouple can work too, but that is a combination of mechanical/digital

    Heck, even a well placed Zeneer diode could have stopped the damage from occuring.

    Maybe this is something you should consider selling? Prices are minimal on a few simple pieces and everything is inline with current circuitry.....Just a suggestion.

    Or at least make the suggestion in the future?

    So, I’m a dummy on LED lights but need to use them because of power supply in the bedroom I chose for my tent. I bought a 2’ x 2’ tent setup. I’m only growing autos in it. There’s enough room for 3 plants. They vegged our perfectly but flowering wasn’t happening like it should so I started looking at the light that came with the setup (300 watt) and discovered that it was for seedlings & veg ONLY! I ordered this light to start over. I know I’m not going to win any “big bud” awards but surely I can get good enough bud for my personal use. Did I fuck up again with this new light? Opinions please.

    Hi guys. Interesting discussion going on in this thread. I'm a relatively newbie grower, so I just started out by picking up an "Advanced Platinum Series P600" which was recommended at Led Grow Lights 101. So far been doing well for me. Anyone else also have experience with this model? Maybe we can give each other tips and advice.
