LED doesn't really have a power for a spotlight, which is commonly in the 1000+ lumen region, and 3000+ for HID, unless you are talking about those tiny handheld with pistol grip, then you might as well buy a LED flashlight with big reflector.
Doug have you seen the motomaster HID at CT? they are pretty good for the price when on sale, and lasts an hour or so.
Lee sounds like you just need a good flashlight, something like
this and some rechargeable batteries.
