I'm not a "real' flashlight enthusiast but do enjoy a decent , but simple light, I have an old 3-D cell midnight Blue Mag-Lite form somewhere in the 1996-2002 era... I don't remember when or why I got this, but I like it's heft and ruggedness.. I wold like to get more light out of it, but I don't want to completely rebuild it... I'm thinking maybe a bout a rechargeable battery system too... All I need is a simple on and off and the adjustability of the existing light... Can you pros recommend a reasonably low cost, not too invasive or intricate set up?... I've used the search feature, but most of the results were pretty old, and maybe there is newer and better ideas... Thanks in advance..
You can't go too high on output otherwise heat will build up and either 1) cook the led 2) cause throttling if it's equipped w/ a temp sensor. The incandescent mag design is not good at getting rid of heat from an led.... no good thermal path.
There are drop ins that provide a thermal path from emitter all the way to the barrel of the light... but be prepared to spend considerably more... and have a much brighter light.
