Yeah, I could probably fit another 240W light bar on the top rail of the roof rack too, but I don't want to melt the paint on the back of cars I'm following :D

120W light bar arrived today, thanks Murray!
Coincidentally it arrived just in time to assist with some high speed camera experiments.
Connected to a 40A Variable (voltage regulated) power supply, I took the following readings:
6V - light starts to turn on
10-11 V - full brightness
10.0V 8.0A draw (=80A)
11.9V 6.7A draw (=80A)
14.6V 5.4A draw (=79A)
15.7V 5.0A draw (=79A)
I will measure light output later when the experiments are finished.
I am not sure how the wattage of the lights are rated. As you can see from the specs above the 120W light only uses 80W. However I am sure the light output exceeds the rated spec based on the 240W light.
When I have a moment I will do the same measurements using my 240W light. (including light output for both).
EDIT - 26500 lm @ 0.5m for the 120W. I can only measure at 0.5 m max in the current experimental setup. Looks like this one has higher than rated output as well!!!
Thanks for the test results Ben, I'm sure everyone is interested in the results.
The wattage calculations are interesting, I suppose the proof is in the pudding.
It'll be good to get some feedback from others once they've had a chance to give their lights a run.
Cheers, Murray
Got mine today!!!!
Hahaha leaves room to manufacture a stone guard for it hey ;)
Does the 120w spot beam version have plenty of spill as well for setting roos at roadside? If so I'd like to buy one please.
