I am looking to purchase a tactical LED flashlight for work. I will need it to be atleast 200-225 lumens. I would like it to be adjustable from a low setting all the way through a max lumen. I need it to have a strobe function as one of the settings and would need it to have a decent clip so that it can secure to a duty belt. So far I like the JetbeamIII,Fenix TK-11, Nitecore Extreme,The EagleTac T10LC2. I am sure there are other good lights out there as well. 5.5 inches is the max in length I would like to carry. I am new to the game of LED's but already know I cannot afford a Surefire. I am looking to spend less than $100. Note: I have a Surefire E2D Executive Defender and Scout Weaponlight in incandescent. I am unsure if I can have these retrofitted for an LED at a decent price. Any help would be greatly appreciated. Thanks in advance.
