My job bought some for me on my patrols because of size and portablility. 110 lumens just isn't bright enough for me. I was told I could upgrade it if I wanted at my own expense. I'm not sure what type of drop in comes with it but it's removable with some sort of lube in the bottom of the retaining compartment. I was wondering if there is a high output emitter upgrade available for purchase somewhere?
