    Default 100W RGB LED driver board for flood lights (WS2811)

    Prototype board works as expected, but more tests are needed.

    A nice CPU sink will do. I am using one w/o fan and it's not that bad. Will do some long period, full power tests today.

    Did more tests today, and everithing looks good.
    There's no flicker, but I will have to put the board in enclosure and test with pigtails and Ts to be 100% sure.
    At full brightness, CPU heatsink got to 80C in less than 5 minutes (PCB was equally hot,) so fan is a must.
    With the fan, temp of the sink was a steady 35C.

    I will now try to find a good source of LEDs and figure out the final cost.
    I am also considering making generic board (LED connected via wires.)

    What voltage will this require? I'm guessing ~36v?

    Any way to get 7-12v off the board to power a fan?

    Yes, 36V @ 3A.

    12V option is a possibility, but I my thinking was that using external DC-DC will give you flexibility.

    Yeah, I guess DC-DC lets you pick the fan or even adjust the speed depending on the fan.

    I will make ~50 of the 100W boards by the end of April. This is just a pilot and I hope to have more in May.

    So sorry for the noob question.
    Do you have a list/links to needed materials to complete this build. I ordered 2 100w versions to get my feet wet.
