I keep a AA maglight with 2 AA Energizer lithium batteries in it and a single white LED. This should go over 200 hours before a battery change is necessary. I was surprised at how bright it is for only two batteries. Not as bright as with the three N cells but lasts way longer. I keep this one as a backup light in case the power goes out for a long time and I run down all my brighter lights. Might come in handy sometime. Who knows.
