The Streamlight TLR-3X Weapon Light (part 59104) 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 2.15 oz.
It is multi-fuel: a CR123A lithium primary cell is supplied, and the light will also run Streamlight's SL-B9 USB-C rechargeable pack if you prefer to recharge. Ambidextrous paddles, anodised construction and an IPX7 rating.

Frequently Asked Questions
Which pistols does the Streamlight TLR-3X (59104) fit?
The Streamlight TLR-3X 59104 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 instead.
How bright is the Streamlight TLR-3X and how far does the beam reach?
The Streamlight TLR-3X 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 (59104) use, and is it rechargeable?
The Streamlight TLR-3X ships with one CR123A lithium primary cell, and it is multi-fuel, so it also runs Streamlight's SL-B9 USB-C rechargeable battery pack if you would rather recharge than replace cells.
How long does the Streamlight TLR-3X run for?
The Streamlight TLR-3X runs for 1.5 hours on a CR123A lithium cell, or 1 hour on an SL-B9 USB-C rechargeable pack.
What is the difference between the Streamlight TLR-3X and the TLR-3X USB?
The light itself is identical. This package (59104) includes a CR123A lithium primary cell, while the USB package (59105) includes the SL-B9 USB-C rechargeable battery pack instead.
