I'm in the midst of converting my incandescent flashlights to LED either by phasing them out or using conversions. I think I'm also going to stop by AAA and CR123 lights and standardise on AA and D lights. I've got plenty of lights that run on AAA and CR123 and its just much easier to get AA and D batts once you're out of the city.

I've got a few Nokero solar powered lights on order just to check them out.

I with dweste and hikermor too. Get my stuff done during daylight and stretch out the life of your lights. When I'm out in the interior in Borneo, the villages here are quite dark at night, maybe a light/candle/lantern or two per household and even then not for long.

Kerosene lanterns have a lot of issues, but they're cheap and fuel is cheap over here in Borneo.
