The Streamlight TLR-3X USB Weapon Light (part 59105) is a compact rail-mounted pistol weapon light cut for the SIG SAUER P365 and P365 XL closed rail systems. 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 around 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 standard 1913 rails and the TLR-3X USB pistol weapon light for 1913 Slim rails. 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.

Frequently Asked Questions
Which pistols does the Streamlight TLR-3X USB (59105) fit?
The Streamlight TLR-3X USB 59105 is the dedicated fitment for the SIG SAUER P365 and P365 XL closed rail systems. It does not fit the P365-XMACRO, which has a 1913-style rail and takes the 1913 version, part 59101, instead.
How bright is the Streamlight TLR-3X USB and how far does the beam reach?
The Streamlight TLR-3X USB produces 500 lumens output and 6,500 candela peak beam intensity, which gives a beam distance of 161 metres.
What battery does the Streamlight TLR-3X USB (59105) use, and is it rechargeable?
The Streamlight TLR-3X USB ships with Streamlight's SL-B9 USB-C rechargeable battery pack, and it is multi-fuel, so a CR123A lithium primary cell can be used instead when you need one.
How long does the Streamlight TLR-3X USB run for?
The Streamlight TLR-3X USB runs for 1.5 hours on a CR123A lithium cell, or 1 hour on an SL-B9 USB-C rechargeable pack.
How is the Streamlight TLR-3X USB charged?
The SL-B9 pack in the Streamlight TLR-3X USB charges over USB-C in about 2.5 hours, and it can be charged either inside or outside the light. Streamlight supplies the USB-C cord as an optional accessory, so use your own USB-C cable or order one separately.
What is the difference between the Streamlight TLR-3X USB and the standard TLR-3X?
The light itself is identical. The USB package (59105) includes the SL-B9 rechargeable battery pack, while the standard package (59104) includes a CR123A lithium primary cell.
