I was looking at branded LED lighting and did some research ended up DIY LED grow light saving $$

    What everyone wants to know, 4x Bridgelux BXRC-35E10K0-L-23's 3500 spectrum wired to HLG-320H-C2100A(the a specifically for the built in dimmer to dim and start on smaller veg plants) and mounted using rails where the COBs can freefloat move them along the railing as needed to direct your light as optimally as possible. For the frame i used 4x pieces of cut down to 2ft pieces, x4 2ft pieces for the outer frame, and then 4 pieces for the inner frame for the cobs/heatsinks to lsy on.

    Back in the day, I built a cabinet wired with a fuckton of shitty standoff LEDs (chips were too expensive).... Never again.

    LED's have come a far way now, they COB's are comparable in output to HPS, while drawing 1/3rd the power, quantum boards blow cobs out of the water. LED is where it's at now.

    No. You have to stop spreading bullshit like this around.

    It takes about 60 to 80 percent of the wattage to match HID. You aren't gonna get there at a third of the power. In other words, to match an SE 1000 watt, you're gonna need 600 to 800 watts of COB/strip.

    A couple questions for you:
    What fan/heatsinks are you running?
    How much were they?
    How are you powering the fans?

    I love DIY. I built a water cooled cob setup a while back but have since turned to strips. If I can find some heatsinks cheap enough, I will convert my water cooled setup to active or passive cooled heatsinks. Also, J Law above is correct, you need more than 1/3 the power of LED to match HPS.

    1/3 is probably correct, he just missed that it's subtracted rather than divided.
