Light bar help

[ArmRippinToys]

Ok guys so I wired my light bar in to my high beams. Used a relay and put a fuse in the power side to the light bar. My question is the sealed fuse holder I got came with a 10 amp fuse. The light bar is a 30" 60 LED@ 3 watts each to equal 180 watt set up with a 10-30v DC range. With that being said from what I've seen people use 15-20 amp fuses on this set up. I don't use the bar a lot but when I have there has been no issues with the 10 amp. Can someone tell me the proper fuse I should be running?

Well amperes=wattage/voltage so with some quick math you can see that a 10A fuse should do just fine.

Ummm 180/12 = 15.

It is! Wasn't really paying attention, don't know why I was thinking a varied input voltage and not just 12.
