Streamlight TLR-8 Sub: the light that lives on the rail
Mounted light is about identification: know what you’re pointing at, instantly. The Streamlight TLR-8 Sub is Streamlight’s answer for duty rails, built to shrug off recoil and weather. This model is configured for the Glock 43X/48 MOS & 43X/48 Rail.
Why it earns its place
- 500 lumens. Enough output to turn a search, a stop, or a dark structure into things you can actually see.
- Up to 1.5 hours of runtime. Power budgeted for a shift, not a demo.
- CR123A / lithium power. The battery logistics your agency already stocks.
- Integrated red laser. Aiming reference for the hours your sights are hardest to find.
- Rear paddle switch. Controls that work with gloves and stress, not against them.
Who runs it
Patrol officers and armed professionals running light-bearing duty or concealment holsters — and agencies standardizing one light across a fleet of rails.
