I got this flashlight as a replacement for the old standard Stinger with the LED conversion. The LED conversion did not survive the drop.
The C4 LED PolyStinger output, in my opinion, is more defined. The switching function between output levels is very thoughtful unlike some models that force you to scroll through all the modes and the Poly body provides a secure grip.
Plus good, fast services from Optics Planet.
Pros: Very bright, good features & function
Cons: Hard to find holster
