Input and Output
Today I lit a string of 48 bright white LEDs with the Stiffler device. They were all very, very bright. According to their spec they consumed 2.5 volts at 30 mA. They were connected in series so by my calculations 48 LEDs x 2.5 volts x 30 mA = 3.6 watts. According to my digital multi-meter (which I do not fully trust) my input was 19.6 volts DC at .35 mA. Hmmmm... that comes out to .00686 watts input and 3.6 watts output. LOL. I am still waiting for my super caps to arrive so that I can do measurements that do not depend upon the high frequencies affecting the DMM. I probably did a basic math error, so please jump in, no hard feelings here. The DMM did not vary on the .35 mA reading with one or two towers.
