Added my ten watt cool white (12v @ 800mA), bringing it up to 2.8A @ 12v, a bit over 33 watts, yielding something like 3000 lumens. Going to set camera up later, and test it out to see how it does as macro flash, illuminating at a close distance. I'll use the arduino to run different pulse lengths to get sufficient exposure at close range. Reports will be made.
