I second the maglite idea. The current 2D mags with LED's perform much better than the older incandescent ones. The batteries last longer, you don't have a bulb to burn out, and they have a much better beam. They can focus to a good spot and throw a beam a long way.
I have a lot of various lights- Streamlight, Fenix, Pelican, Inova, Nuwaii. My current EDC lights are a Fenix LD01 in my pocket and a PD32 in my briefcase. The PD32 uses 2 CR123 batteries and is very bright, I think something over 300 Lumens, but the 2D maglite will throw a beam farther. I think it is a bad idea to recommend a CR123 light for casual home use because of the expense and/or difficulty of getting batteries, but if someone is willing to go through with that and pay for the much more expensive light then the big lights such as the Fenix TK35 might be a good idea.
