It looks amazing, but I have a few questions. My machine produces14.5Volts when the motor is at speed, so that would be around 40amps pull at 580Watts using P=VI. Did you install the alternator? Did you buy special rocker switches and other hardware as most of the rocker switches I see are 20Amp? I haven't seen any 40Amp switches but haven't specifically searched for that.

Just curious because I was looking at two row, but was worried the power draw would be too much.

P=VI is only for resistive load, not LED. Bar draws under 10 amps
I am not sure I understand the resistive load comment, if you could explain that more I would appreciate it. Did you put the bar on a power supply separate from the machine to measure the 10amp pull?


If you look at that light bar it is 240Watts and pulls 18.2Amps at 12V which is very close to the P=VI ---- 218.4 Watts = 12V * 18.2Amps My guess is the bar is rated for 240Watts but won't fully pull that amount of power.

I will run a test tonight with a small 12 inch light bar and see what I get. I have a power supply and can measure the current pull and not use my machine. I know my R1 3ft light whips pull 5 amps each (10 amps total) when they are white color at 14.5Volts. It surprised me how much current they pulled.
