    I'm a newbie with led and electronics. I'm an electrician trying to do some home made stuff. I know alot of these leds can be found on ebay for good prices. Can someone tell me what board this is? I've found 20 watters but not close to their lms. Am I on the right track with one on ebay. I'm trying to make the same fixture for myself.

    eBay one looks OK to me but it mentions something about cooling so may want some PWM circuitry.
