For use outside the house I've pretty much switched 100% to a headlamp - specifically the Princeton Tec EOS. Not having to hold them is just so handy (no pun intended), they're tiny, lightweight, very bright, and durable.

I recently bought the tiny Fenix P1D Cree light (uses the single 123A battery) to have as a small backup for the EOS. It is AMAZINGLY bright for its size and has a long shelf life (lithium), but kind of expensive - about $70

If car camping I'll usually bring a Coleman lantern to help light things up for the Scouts.

Inside my car & house I continue to use an array of somewhat abandoned field handheld lights - my favorites are the 4AA Underwater Kinetics LED (bedroom), the 4AA Streamlight PolyPro LED (car), the Princeton Tec Impact XL (family room), and the little 2 AAA River Rock LED lights from Target (living room & bedroom). The Underwater Kinetics has more of a flood beam - very nice consistency. The SL PolyPro is more of a spotlight. The PT Impact XL isn't as nice as the UK or the SL PolyPro, in my view.
