32" YitaMotor Light Bar - Specs Check

[CampHamp]

I just received two of these by FEDEX from Walmart:

YITAMOTOR 32INCH 420W LED LIGHT BAR Spot Flood Combo Fits Ford Offroad Truck SUV ATV 30"in

They were $22 each, free shipping to NH.

In order to select the correct wire gauge and fuse, I needed to know the actual amp draw. I thought that I would share this info in case someone wanted a cheap light bar and wouldn't need to do the amp test for themselves.

Advertised Capability: 420W Halogen = 5400 lumens

Test Results:
Battery Level: 12.21V
Draw Amps:    5.43A
Implied Watts: 65W

Conclusion:
65W LED = 5850 lumens
 

I used this "watts to lumens" calculator.

According to the chart, below, it's safe to use 16 gauge up 40'. Also, since my dash switches are rated to 20A, I will not bother with relays.
