That's a really good point. I don't know why I didn't realize that. They have to divide the potential based on their resistance at that current.

I think you just saved me one of the four power packs on my next experiment.
sideshowmel Reviewed by sideshowmel on . Designing LED grow panel Anyone that could be any help in my LED project, feel free to chime in. This light panel will be put in a single Rubbermaid grow box. I plan to run Luxeon Rebel LED series, in a Saber Tri-Star chip. Essentially, there's three Rebel LED's on one chip, having a 10V forward voltage, and the ability to run 700 mA. I want to run 3 reds, and 3 blues. The reason why I want to use equal colour amounts is because it makes it easier to wire for drivers, and the red colour LED's are more efficient than Rating: 5
