freeballer... there are a lot of folks more qualified on that question than I, but just went through upgrading my EDC and hurricane supplies.... I am trying to standardize to AA and D cells... my hurricane electronics are AA, and switched to Sanyo Eneloop AA NiMH rechargables, with a solar and separate 12v/120v charger...for AA lights I selected a...Black Diamond Orion headlamp (pretty high end), Coleman High Tech mini LED area lamp, Fenix E21 (seems to be pretty well made), and still have a couple of the larger 2D LED Maglights... for EDC, my key ring light is a Fenix E01 with lithium cell and sharing a multi tool pouch with a smaller multi tool is a Streamlight ProTac single cr123 110 lumen unit
