I don't think you'll be able to - the wattage rating is some sort of flexible 'equivalent' to an incandescent lamp.all im trying to do is work out the amperage.
These ones are also rated at "144W" each, but from the Q&A:
"If anyone was wanting to know how many Amps these things draw it's not very much. Each individual one draws about 1 - 1.1 Amps. With both connected they were drawing about 2.1 amps."
These ones are "120W" at the top of the page, but in the specifications:
" Power: 120W
Actual current at:24V=1.4A,12V=2.98A"
These ones also claim to be 144W, but from the comments (one star review):
"I have attached a photograph of the actual 1.99 amp draw of one 7” light bar in a circuit running at 13.2 volts So, Watts = Current times Voltage. Or, 1.99 amps X 13.2 volts = 26.27 Watts"
I've also seen this little disclaimer in a few listings:
"Wattage : 144W LED light bar(Actual power is lower than rated power)"
Best hook them up to a battery and measure the actual current draw!
