The DeWalt work light is great, but it is big and rather heavy. It is also one of a couple 18V tools that will not take the LiIon pack without modifications (the other is the corded/cordless wet-dry vac). Supposedly DeWalt will modify these tools at a service center to accept the LiIon packs. It's a simple shaving off of some plastic inside the battery receptacle to clear blocking tabs that only the LiIon batteries have.
