    Yes, I am working on it, should take ~4 weeks.
    If you need it now, I can probably find few of them.

    I've finally finished building my first one of these. Red works fine, but green is very dim, and I get no blue at all. Doesn't matter if I drive it with a controller or with the test pads on the board.
    Anything obvious that I'm missing?

    Can you email pictures of your board to me for visual inspection?

    I've not built a second one of these, and was very careful with soldering. This one has the exact same problem as the first. Using the test points, red seems fine, green is very dim, and no blue at all. Since both boards behave identically, there must be something I am consistently doing wrong. I've tried controlling with x-lights, and I get the same results - red fine, green very dim, no blue. I am running these at 12V.

    Hi, the answer to your problem is in your last post. 20W boards require 24V supply (20V-24V) Only 10W boards can run on 12V.
