The Streamlight TLR-7 X USB ultra lightweight gun light is a rechargeable tactical weapon light built for shooters who want the flexibility to top-load either a USB-rechargeable battery or standard CR123A lithium cells. At 2.64 ounces with the included SL-B9 battery pack and just 2.58 inches long, this compact rail-mounted light delivers 500 lumens of output with a 140-meter beam—enough reach for home defense, duty, or low-light training without adding noticeable weight or bulk to your pistol or rifle platform.

The TLR-7 X USB ships with an SL-B9 protected lithium-ion rechargeable battery and USB-C charging cable, so you can top it off at home or the range without buying replacement batteries. If you're field-dependent or prefer the simplicity of CR123A cells, swap the battery in seconds—no tools required. The rear paddle switches are ambidextrous and ergonomic, giving you both HIGH and LOW modes; they include a user-enabled strobe function and a safe-off feature that prevents accidental activation and unnecessary drain.

Built from durable anodized aluminum and rated IPX7 waterproof to 1 meter for 30 minutes, this light is sealed against dust, mud, and weather. The rail grip clamp attaches and detaches securely without requiring your hands in front of the muzzle—a critical design detail for safe mounting and removal. The TLR-7 X USB comes in Black and is assembled in the USA.

Frequently Asked Questions

Can I use this light with standard batteries if I don't want to recharge?

Yes. The TLR-7 X USB accepts either the included Streamlight SL-B9 rechargeable battery or a CR123A lithium battery—simply swap whichever power source you prefer. If you're in the field or prefer disposable cells, CR123A batteries work just fine; you just won't get USB charging capability with a standard cell.

How long does the battery last on a full charge?

With the Streamlight SL-B9 rechargeable battery, the light runs for approximately 1 hour. If you use a CR123A lithium cell instead, runtime extends to 1.5 hours. Actual duration will vary depending on whether you run the light in HIGH or LOW mode and how often you use the strobe.

Is the TLR-7 X USB waterproof?

The light is rated IPX7 waterproof, which means it can be submerged in water up to 1 meter for 30 minutes. It's sealed against dust and moisture, so it holds up to rain, mud, and harsh field conditions, though continuous submersion beyond the rated depth is not recommended.

What switch configurations does this light have?

The TLR-7 X USB comes with ambidextrous rear paddle switches that offer HIGH and LOW brightness modes, plus a user-enabled strobe function. The safe-off feature prevents accidental activation, which saves battery life and keeps your light from turning on unexpectedly in a holster or pack.
