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.

Also, since my dash switches are rated to 20A, I will not bother with relays. Link to comment Share on other sites More sharing options...
