Streamlight TLR-3X Sub-Compact Weapon Light - 500 Lumens - SIG P365/XL - CR123A

The Streamlight TLR-3X delivers 500 lumens and 6,500 candela from a 2.75-inch housing mounted on a SIG Sauer P365 and P365XL closed rail — a multi-fuel sub-compact weaponlight with momentary, constant-on, and strobe modes, ambidextrous paddle switches, and IPX7 waterproofing, built for handguns where size and weight matter as much as output.

The Streamlight TLR-3X is a sub-compact rail-mounted weaponlight delivering 500 lumens and 6,500 candela peak beam intensity with a 161-meter beam distance. It mounts to SIG Sauer P365 and P365XL closed rail systems using a reversible clamp with multiple paddle switch widths and heights for a broad range of handgun compatibility. Battery: CR123A lithium (included). Length: 2.75 inches. Weight: 2.15–2.25 oz. IPX7 waterproof to 1 meter for 30 minutes.

500 lumens in a 2.75-inch housing is a meaningful output-to-size ratio for a sub-compact weaponlight — enough candela to identify a threat and maintain situational awareness at defensive distances without adding the bulk that larger lights impose on compact and subcompact pistols. The 6,500 candela peak beam intensity focuses that output into a beam with useful reach, and the custom reflector balances the center concentration with peripheral illumination so the shooter maintains situational awareness beyond the primary target. The multi-fuel capability allows the light to run on either a standard CR123A lithium battery or a Streamlight SL-B9 rechargeable pack, providing flexibility between rechargeable daily carry and field-replaceable battery backup — both options deliver the same 500-lumen output and 1.5-hour runtime. This variant ships with one CR123A lithium primary and is fitted specifically for the SIG Sauer P365 and P365XL closed rail system — a proprietary rail format that does not accept standard 1913 Picatinny weaponlights. The SL-B9 rechargeable pack is also accepted as an alternative fuel source. The ambidextrous paddle switch design includes multiple widths and heights in the kit to achieve the correct switch fit for the user's specific handgun model, allowing momentary or constant-on activation from either side without repositioning the support hand. The reversible clamp system accommodates both short and standard railed handguns. The face-cap battery access allows battery replacement without removing the light from the firearm. User-activated strobe mode provides an additional disorientation tool. BOROFLOAT glass and impact-resistant polymer construction meet the durability demands of a carry weaponlight. Operating temperature range: -40°F to +120°F (CR123A) or -4°F to +120°F (SL-B9).

Output: 500 lumens / 6,500 candela / 161m beam distance. Runtime: 1.5 hours. Battery: CR123A lithium (included). Mount: SIG Sauer P365 and P365XL closed rail. Length: 2.75 in. Weight: 2.15–2.25 oz. Modes: momentary, constant-on, strobe. Switch: ambidextrous paddles, multiple widths/heights included. Waterproof: IPX7 (1m, 30 min). Operating temp: -40°F to +120°F. Includes: mounting kit with key, paddles, multi-tool, and one CR123A battery. Compatible: SIG Sauer P365/P365XL closed rail systems.

500 lumens and 6,500 candela in a 2.75-inch sub-compact housing balances output and size for compact and subcompact carry pistols. Multi-fuel CR123A / SL-B9 compatibility provides rechargeable convenience with field-replaceable backup. Ambidextrous paddle kit with multiple widths and heights fits a broad range of handgun rail sizes. Face-cap battery access eliminates light removal for battery changes.

The right sub-compact weaponlight for SIG Sauer P365 and P365XL closed rail handgun users who need meaningful output in the smallest practical housing — 500 lumens, ambidextrous operation, and IPX7 waterproofing in a 2.75-inch multi-fuel package.
