    COB efficiency Spreadsheets

    More power? This says to me that the quantum loss may not just be from Current. Higher Voltage seems to waste electrons also. If this is correct......

    I was thinking mix up in several colors of white COBs but, then I think, why bother? :) Need science, not guess.

    Well, you go fuck a duck. Don't put words in my mouth. If you don't find it intuitively and didn't mean that, so what? I thought you did. That is exactly what you said. I am agreeing with you, weirdo. :) And to not accept my explanation is just being rude. I am plain spoken as you should...

    Marijuanna drug test pass or fail?

    There is a sure fire way. I know because my roomie got a truck drivers job, the one where you line up, haul and dump debris all day long. Random 15 min call for Piss Test. It can happen anytime. Well he can't stop smoking it just for a job, right? So, he keep with him, a quart of water and...

    3- a thought out response of total sincerity not reflecting on you in any negative way; or 3a - to be taken at face value. :)

    Yes, funny how the Calculus is somewhat intuituve when presented this way.

    Best color temp for veg?

    Seems to me bigger plants carry bigger buds, and since I only want an 8 week veg period, warmer light makes the plants bigger, faster.

    First LED build CXB3590

    Graphite and aluminum are not compatible. Even pencil marks can corrode.

    So, of course. Just be careful. They show an edge, not pulled down all the way.

    Hold down force on the cob cannot exceed 75 ft pounds on the screws. It's in the spec for both holder and COB.

    Heatsinks for DIY LED lamps

    That nice. Will you be putting sides on it, to make a full channel against the roof? The main thing here is your sink won't shed heat evenly. The end near the fan will be hotter, since it only gets the hotter air for cooling....if you are completely ducted. Else, if no duct, the fan end is...

    @heckler73. Math wizz!! CRI in Horticulture is only loosely coupled to efficiency, but we see from the charts there is a penalty to pay, there, for highest CRI.

    Best color temp for veg?

    This is a strange thought puzzle to me. If 100 CRI is all colors appear just like outdoors. And LPS can be slightly negative Then -100 CRI makes you see no color, all gray? Or do colors swap to opposite and/or blur to the same, like in color blind? What is the other end of the scale? What is...
