    COB efficiency Spreadsheets

    Yep something wrong , only 54.6 watts it's drawing. Lucky I have a few extra lights. I put a passive cooled @1050mA with a quad driver and it looks much better. Has anybody ever had to return a driver, how easy is it.

    COB efficiency Spreadsheets

    OK my 36v cbx3590's seem to be brighter @ 700mA than the 72v although they do have different drivers, HLG 185 700 AND INVENTRONICS 160w quad driver 700mA. I've been wondering for a few days about it. If anyone needs advice on roofing I might be able to help you :eyesmoke:

    Why do HID lights have better penetration?

    My feeling exactly, I can live with it or without. I notice it's sooner or later, a little less or a little more.

    I had good experience with KB. He sent photos before hand showing them in original packaging and circled the writing on each package telling me what to expect. My hopes were fulfilled when they fired up to go to work. He seems to be a really nice guy.

    I finished 3 of my passive cooled lights, taking a infared reading on the top the cob after 5 hrs. they were reading 25.6 - 26.3C. You can see how I hooked them together, it works better than I thought L metal and some square tube. I riveted the L metal to the heat sink and added some self...

    DiY LEDs - How to Power Them

    I,m on 120 and they work fine when grounded but tried 2 different timers and both were the same they didn't work, Both timers are not grounded. I'm usually good with electricity but this baffles me.

    DiY LEDs - How to Power Them

    I been thinking and I think it's because it's not a grounded timer. It works in anything that has a good ground.
