Passive? I see no mention of a fan....passive cooling, each sink is good for 2.5 watts /inch....is that the problem?So I got my lights hooked up and working, 2 heat sinks 5.88" x 19" with 2 cobs on each(3590 3500k 36v) being run by HLG-185H-C1400.
My question is how hot should the heatsinks be? I touched for a few seconds and they are really hot, just wondering what I should be observing if any thing.
Active cooling should place you in the range of 190watts for each sink, so that shouldn't be an issue either
