Sometime ago, maybe a year or more I purchased a Thrunite Saber BLF through a group or special buy. Today I ran across it in a drawer, and cannot find if it will operate on a 14500 battery.
I am sure there are those here who purchased the same light and can answer the question as to whether it can use a 14450 battery. I note the newest versions have an adapter so that a CR 123 can be used.
