Was close to buying the ChaetoMax for a refugium in the back of my biocube 29 and then realized this was a great learning opportunity... So I'm gonna do my first LED dyi. 4 x 3w LEDs (Forward Voltage is 2.3V@700ma) I am assuming that I need a driver than can supply 700ma of current or less... at 9.2v (2.3v x 4 leds)... Less if I want to dim? This driver can't supply low enough voltage? "-Max # LEDs -7 LEDs (or combined LED voltage not exceeding 24.5V) -Minimum Voltage output - 12.5Vdc" Is there a min number of LEDs a driver can drive?
