Bazooka light connected to Anderson ports

So I cut my 12v battery clamps and spliced in the properly oriented Anderson PowerPole connectors in order to plug my bazooka light into any delta with anderson ports. This includes me D3M+, DP, DP3, and DPU. I guess using a DPU is a bit of overkill for these LED lights, but I did it in the interest of science. I wonder how long 6kwh of battery can run these lights?
