The LEDs are super bright SMDs on custom programmable modules called "megabrites" from macetech.com. In theory, they won't run 300mA the whole night, since they're doing PWM, and most of the time idle at around 100mA. What about the 6V batteries and 12V charge controllers? The modules require 6-9V; ...

I'm struggling with the decision for my art project as well... I have 120 RGB LED modules, each pulling 100mA at idle to 300mA at 6V when reacting to sound or movement. According to my calculations, that means: 120 x 200mA average = 24A, x 10 hours/night = 240AH/night. Splitting the power up between...
