    HLG 185 problems

    Is the dimmer disconnected? An incorrectly wired dimmer/size could do that Cobs from kingbrite? Not assuming they are bad or anything.. Problems like that are stressfull no doubt

    When are the commercial cob panels coming

    I'm guilty of using the words easy a lot. But, compared to other things I've taken on, I think it is. I see people do amazing things with their hands pretty often whether it's building a car, or a boat, renovating homes. It just takes a desire, a passion, to do it. In case you haven't noticed...

    The larger rapid version looks to be made to be air cooled. Even has a cutout for the fan. Not sure I love the overall design either.. It is priced pretty good

    It'd be a good topic for a new thread. I don't know much about it personally. Hard to say without doing a Tj test to see if there would really be that big a difference

    Thanks! Check rapid led for anodized heatsinks. Looks like they have skinny and wide versions. Not really familiar with any others, just remember seeing them there before.

    With cobs - Why a panel?

    Your assuming everyone needs perfect light distribution. In that case greengenes has shown that produces awesome results, most probably the best. Can't really argue with a light meter..lol Speaking for myself... Perfect distribution means a fixture near the size of the area. Easily achievable...

    Led build~ 2' heatsink 200w

    Thanks...I've had the same experience, small difference in different types of coolers. Supra and his heatsink thread would be the best way to calculate that. My personal preference is always fan cooled. Even just a little fan speed will drop temps significantly. I like high powered leds and...

    Led build~ 2' heatsink 200w

Even when their brand new I like my metal shiny. Using a stiff bristle brush and a little aluminum polish I clean it up...

    Heatsinks for DIY LED lamps

    I love it....looks nice like that too.. Kinda surprised its cooler with less metal though. And the extra metal between cobs...makes me wonder if they are even conducting much heat? But 20c less....its working!
