Compact Tactical Weapon-Mounted Light w/Strobe

The TCM-550XLS Compact Tactical Weapon-Mounted Light uses a super-bright LED rated at 550 lumens working in conjunction with a precision-engineered total internal reflection (TIR) lens to create a bright white beam of light rated at 136 meters. This weapon light features completely ambidextrous and intuitive rear-facing toggle switches on each side of the light to operate momentary, constant-on, and strobe lighting modes. The housing of the TCM-550XLS is constructed from aircraft-grade 6061-T6 Aluminum with a polymer rear housing. Includes four handgun-specific modular rail inserts (pre-configured with C1 insert for Glock pistols), two spare Allen screws, an Allen wrench, and one CR123 Lithium battery.

    TCM-550XLS: 5  of 5

    I have literally one for each of my semi-auto handguns. These are the best, practical, weapon mounted light for the CCW person. Plenty of light for the home defense weapon too. The features on this light are as good as much more expensive, and bigger named lights. This light is compact and user friendly. Rugged too. I carry one every single day...

    TCM-550XLS: 5  of 5

    I'm a holster maker and I had a customer that wanted a holster built with a Nightstick light. I didn't have one so, I acquired one and....it was love at first light! (pun intended!) Seriously, this small light has all the functionality of much larger and much more expensive lights. The ONLY drawback is availability. Locating a distributor in my area is a chore. Hopefully the news of this light will get out FAST and more distributors will come online quickly. Seriously, I need one of these for each of my handguns. I can make holsters with them that work with or without the light. Awesome if you ask me!
    Great product, THANKS!
