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.
Had the old version, non LED, of this. One advantage over current small AA or AAA Flashlights is that it was as much a weapon as it was a flashlight. You hit someone with it, they knew they’d been hit.
It looks like a pretty nice light. The website has some good info as well.
The only thing I could not find was the manufacturing country of origin.
I have a few LED Maglites and they seem to have a parasitic draw on the batteries.
In the truck glove box after about 3-4 months I always have to put new batteries in.
I found a 4-D Maglite at Goodwill for $6.00, cleaned out a little battery acid, purchased an LED bulb, a glass lens and a window breaker butt cap. Works great.
