Hi Fishunt,
I think there might be some other options for you. Consider the Ridgid panel light which is 2,500 lumens and can run on both AC power and a Ridgid battery. I bought one of these and liked it so much that I went back to HD and bought another one, the Ridgid flood, and the Ridgid tripod! They have a deal going right now if you buy two Ridgid bare tools you get a charger and 2 ah battery free. You'll have a little more flexibility with the panel light and making it just throw in one direction or making it a near 360 degree light.

As far as the Milwaukee stand light, they actually have a deal going on right now where you can buy the light and it comes with both a 5.0 ah battery AND a charger for $199 which is going on until 11/30.
