When I started my law enforcement career 41 years ago, my very first duty flashlight was an old 6D-cell Rayovac that had belonged to my grandfather. Though it served me well as a part-time deputy, I found it wasn’t quite up for the stresses of full-time police duty. My field training officer recommended the Maglite brand flashlight to me. I purchased a 6C-cell model, which served me well for a number of years. Though Maglite no longer has the 6C-cell available, there is the ML300L 4D LED Long Running flashlight.
