I'm using the Brinkmann Tuff Max LED light AG sells. It's very bright and takes 6 AA batteries (not a rechargeable light). The battery life is pretty good for how bright it is and that it's dual pivoting LED lights. Problem is, build quality of the light is poor. I've had it for 5 months or so. Since new, I've had to take it apart to fix a bad wire. Also? The little groove lines that hold the battery door on broke, now the door is being held on with Velcro straps. Yesterday I went to replace the batteries, and the battery carrier was stuck in the light. I gently tried to remove it, when all of a sudden, the battery contact points that sit on the carrier flew out. They just float in there. I'll have to epoxy them in. When I get done beefing it up and all the repairs, it'll be a great light. However, I'd still recommend it, as I feel it's very bright and the right light color for finding defects. Also the dual swiveling light is nice.
