It's not heat that's the problem, but the difference between using 700 mA to drive 3 high power LEDs in series, and 2.1A to drive them individually. That's the difference between 71 hours and 24 hours of battery life when using a 50AH Optima 34 battery, not even considering other powered devices. >I am not even the one you are talking to, and you are pissing me off >with your holier than thou attitude.
