M-3B: 3 LED Retrofit Bulb for Maglite

Convert your ordinary flashlight into this energy, money saving flashlight (see photo above), I replaced an original MAG-LITE flashlight with this LED bulb, I still can adjust its focus of light beam. this LED light-bulb allow your batteries last many times longer than the filament bulb, it is manufactured using the genuine Nichia LED, the LED's lifetime are rated over 100,000 hours, please don't make your own assumption, the intensity and life expectancy of LED will be greatly degraded. 4.5 Volt - it requires 3 batteries to operate 6.0 Volt - it requires 4 batteries to operate
