I just bought this light from Advance Auto Parts. It is one of the most powerful spotlights I have ever held, and to my knowledge is very likely to be the new longest throwing Incandescent spotlight on the market. I am very pleased with it!
This light uses a 12V 120W/60W H4 Halogen bulb, and a 12V 7ah SLA battery. It comes with both AC and DC adaptors. It also has LED lights on the bezel that can be activated with a different switch than the one that controls the main beam.
I will post beamshots of it tonight if it is not raining. Here are some pictures I took of the light itself.
