Streamlight ProTac HL5-X USB Rechargeable LED Flashlight with SL-B26 Battery - Black Aluminum

The Streamlight ProTac HL5-X USB rechargeable LED flashlight delivers serious brightness for tactical, search and rescue, and professional use. With a massive 3500-lumen output on high (when powered by the included SL-B26 rechargeable batteries), this light throws a 452-meter beam and cuts through darkness at distance—making it ideal for perimeter checks, night operations, or emergency response where you need maximum illumination and reach. The aluminum body is built rugged, impact-tested to 1 meter, and sealed to IPX7 waterproof standards so it handles field conditions without compromise.

What sets the ProTac HL5-X apart is flexibility. It ships with two Streamlight SL-B26 protected Li-Ion USB rechargeable battery packs, but you can swap in four CR123A lithium batteries if you need longer runtimes or don't have access to a charger in the field. The TEN-TAP programming system lets you dial in three different modes: high/strobe/low, high only, or low/medium/high. That means you can choose brightness and features that match your mission—whether you're signaling, preserving night vision with low output, or going all-in with maximum throw.

Runtime varies by power source and brightness: on SL-B26 batteries you'll get 1.25 hours on high, 3 hours on medium, or an impressive 11.5 hours on low. The included rubber grip sleeve provides both thermal insulation and a secure hold, while the anti-roll head keeps the light in place if you set it down on a flat surface. At 9.53 inches and under a pound and a half, it's portable enough for a pack or vehicle without being bulky.

Frequently Asked Questions

Can I use regular CR123A batteries in the ProTac HL5-X?

Yes. The light accepts four CR123A lithium batteries as an alternative to the included SL-B26 rechargeable packs. Runtimes and output will differ—for example, high output drops to 2500 lumens and the beam reaches 385 meters on CR123A, compared to 3500 lumens and 452 meters on SL-B26.

What's included in the box?

The ProTac HL5-X ships with two Streamlight SL-B26 protected Li-Ion USB rechargeable battery packs ready to use. You'll also get the light itself with the rubber grip sleeve already attached.

What programming modes does it have?

The TEN-TAP system lets you choose from three user-selectable programs: (1) high/strobe/low, (2) high only, or (3) low/medium/high. This lets you tailor the light's operation to your specific needs.

Is this light waterproof for diving or submersion?

The ProTac HL5-X is rated IPX7 waterproof, which means it can handle immersion to 1 meter for up to 30 minutes. It's not designed for extended diving or depths beyond that rating.
