Emergency lighting in our home is no problem. We have (yes, I am Flashaholic) a hundred or more flashlights, both incandescent and LED’s. Most are battery powered, but we also have some solar powered and hand cranked versions. We have several house current, 12V and solar battery chargers for NiMh batteries. We have AA to C and D adaptors to allow the batteries to be used in a variety of devices. We have a stock of both alkaline and lithium batteries, in various sizes. We have several LED and incandescent lanterns, both battery powered and solar powered versions. We have propane, kerosene/lamp oil and white gas lanterns as well. An assortment of Krill lights, LED light sticks, chem. lights, and light diffusers to fit over flashlights. Since we do some 18thcen reenact. We have a number of candle lanterns and both buy and make our own candles. Pete
