Made a few hard choices but I had to think realistic such as cost, availability and low maintenance plus a margin of safety.
At my home and a couple of stationary bug out locations I replaced all my coleman duel fuel lanterns with the streamlight (44931) siege led lanterns, keeping a couple of the coleman propane lanterns for the brighter light if need be, I added a propane conversion kit to my coleman duel fuel.
White fuel and gasoline is no longer cost effective plus white fuel isn’t as widely available as it once was, propane will keep substantially longer then white fuel and gasoline and the same be said about my kerosene lanterns, I effectively eliminated all white, gasoline and kerosene fuels from my emergency stock thus all equipment that couldn’t be converted to propane. now all I have to focus on is battery rotation
I have the UST 30day lantern and impressed with it, does hold up for a month on 3 Dcells, I ordered UST 60day lantern though this one uses 6 Dcells, the streamlight lanterns will be my primary lights in an emergency, the UST 30day originally purchased for the outhouse, plan is to turn it on at night to its lowest setting and turning it off during the day, I was figuring on it lasting close to 2 months since it was designed to run 30days on the low setting without being turned off on 3 Dcells.
I already replaced all my krypton bulb flashlights with led a couple of years ago
