Promotion=more money. Buy a new Stinger. Better yet, make your dept. buy you a new one.
The drop in LED that I bought from Amazon works great. I actually bought three. Then a light rolled off the counter onto the floor, which isn't that bad of an impact for a Stinger. The led FELL THE FUCK OFF the circuit board, making my stinger into an ineffective impact weapon producing zero lumens.
The new LED stingers are great.
My brother showed me one of these he uses that someone gave him:

I am not sure if it was that exact light, but it did take c-cells. The light output is nothing short of amazing for that price point and the mirror/lense cast a perfect wide beam that can be focused down to take bone density exams from about 500 feet. I can't say how they stand up to abuse, but I would buy this set if I didn't already have flashlights to light up my flashlights...............
