The Streamlight TLR-3X USB Weapon Light (part 59101) is a compact rail-mounted pistol weapon light cut for standard MIL-STD-1913 rails. It produces 500 lumens output and 6,500 candela peak beam intensity for a 161-metre beam, from a body 2.75 in long weighing 2.25 oz.
This is the rechargeable package: Streamlight's SL-B9 USB-C rechargeable battery pack is in the box, and the pack charges over USB-C in about 2.5 hours either inside or outside the light. The light is multi-fuel, so a CR123A lithium primary cell can be fitted instead. Ambidextrous paddles, anodised construction and an IPX7 rating. Note that Streamlight supplies the USB-C charging cord as an optional accessory rather than in the box.
How it compares
Same light, different battery package: the TLR-3X with a CR123A cell instead. Different rail? See the TLR-3X USB pistol weapon light for 1913 Slim rails and the TLR-3X USB pistol weapon light for the SIG P365. Want more output on a subcompact? The TLR-7 X sub 725-lumen subcompact pistol light. Read the Streamlight TLR comparison guide, or browse the full Streamlight TLR weapon light range and all rechargeable weapon lights.
Ideal for
- Pistols with a MIL-STD-1913 rail, and replicas carrying the same rail
- Airsoft skirmish and milsim night games on pistols with the matching rail
- Northern Ireland permit-held pistols
- Lightweight carry setups where weight on the frame matters

What battery does the Streamlight TLR-3X USB (59101) use, and is it rechargeable?
