One mobile 500 watt Halogen light would do the trick. Brace yourself before you turn it on and point it at your paint though because it will reveal things that you hadn't seen before gauranteed. All the home centers have the 500 watters that are on tri-pod stands that would probably be the best bet for positioning the light just right.
I lived in Sac for a year and a half and Chico before that so I know how HOT it gets up there in the summer!
