Thank you for your input.
I had thought about this as well, being these leds are rated from 9-30 volts. But, I assumed there were resistors built into the leds that would compensate for different input and not allow greater wattage. I assumed the actual leds received the same amount power between that range, and figured they had some sort of resistor. I tested them at various voltages, and noted the amperage change. I would see a 3 amp draw at 12 volts, but a 2.5 amp draw at 14 volts. This points me to thinking the lights are only 36 watts no matter what the input voltage is.
I was just a bit surprised at how much less consumption there is than I originally planned for. I will just be sure to get the lights and test them prior to purchasing wiring and fuse blocks in the future.
