I'm setting up my shed/backyard for solar lighting. Have already got 12v CFL lights for the shed (2 wires pos/neg to the battery) - no problem.

My 12v Led Floodlight just arrived from HK and it has 3 wires (brown,blue,yellow/green). Google tells me brown =live, blue =neutral, yellow/ green =earth). So is it correct if I connect brown to positive from the batteries, blue to the negative and the yellow/green to part of the metal frame of the shed? I know that will work but just checking that it's the right way to do it.
