SteveP, yes they can, I've been using standard Energizer AAA lithium cells in the 2aaa E-led Pocket light (same light,different body configuration) for several years with no problems. For the pricepoint and toughness -nice lights.

There have been a few reports of shorts in the Pocket Lights though. I had one get so hot that the plastic body actually deformed. I really wouldn't want to have that happen with lithium batteries. The Penlight seems to be safer in that respect, I never heard of any problems with the Penlight.
