Coast states that this light was “specifically designed with law enforcement officers in mind;” this fact was apparent throughout our evaluation. Unboxing the TX7R reveals a huge assortment of accessories, including three batteries (two lithium packs and a AAA carrier), two chargers, and two belt holsters. The light is constructed from solid aluminum, with two heavily-textured collars for secure grip. Sliding the head forward or backward adjusts the Long-Range Focusing Optic between a clear floodlight and a tight spotlight. If long-distance illumination is a priority for you, this light clearly excels in that category with its claimed maximum effective distance of nearly a 1/2 mile (2,240 feet). Both high and strobe modes are powerful, but we wish this light offered a low-output mode for close-range use.

Pros:
-The head's short 1/4-inch travel and textured rubber collar make it exceptionally easy to adjust the focus one-handed, even when held in a reverse grip.
-The strobe automatically alternates between faster and slower flashes, creating a clear nighttime distress signal.
-Batteries can be recharged while inside or outside the light, so you'll be able to charge your backup while continuing to use the primary.

Cons:
-The rear rubber collar isn't fixed to the body, tending to shift and slide around over time.
-We would've preferred a more appealing color for the collars, either something bright and high-visibility or plain black.
-Lacks low-output mode
