LED lightbar power/current draw - Claimed vs Actual

Thanks Leigh. I am trying to find a brighter light than the current 20W fitted. So I bought them and decided to do an experiment out of interest.
Interestingly, I also measured an 18W round LED work light and it was showing 15.6W.
Dbc, the current showing on the multimeter is 0.1 to 0.2A lower than the watt meter.

My thoughts are that some people based their purchasing decisions on wattage/lumens or a combination of both. Wattage has an implication on current draw on the alternator and wire selection. There appears to be a correlation between wattage and lumens.
I'm trying to replace a 20W, 1900lumen light http://www.ebay.com.au/itm/MUDDOG-5-...wAAOSw6WdXiEnP
with a 60W 4800lumen light http://www.ebay.com.au/itm/2x-4inch-...0AAOSw-K9ZD-dn
Most punters will conclude that the higher the wattage, the brighter the light output. I don't have a light meter for testing but the next experiment is to rip out the existing 20W light and measure the power. Then try and assess the light quality by eye. Granted that one is flood and the other is spot.

The seller didnt realise I had a 150amp power analyzer meter.

Claimed - 693w
Actual - 174w
Amps Max - 14.1
Absolute credit goes to the seller, as he accepted the findings, full refund, and sent a pre-paid label for the return postage.
BUT, still sells them as advertised 693w.... thats the part I really dont agree with.
