The handheld ProTac HL-X utilizes dual-fuel engineering. It can run on a single rechargeable lithium-ion pack or two standard disposable lithium batteries. Light output and operational runtimes adjust based on the selected cell type.

When using one Streamlight SL-B26 (or 18650) Lithium-Ion Rechargeable Battery:

• High Mode: 1,000 Lumens | 27,100 Candela | 330-meter beam distance | Runs 1.5 hours

• Medium Mode: 400 Lumens | 10,000 Candela | 200-meter beam distance | Runs 3.5 hours

• Low Mode: 65 Lumens | 1,600 Candela | 80-meter beam distance | Runs 23 hours

• Strobe Mode: Designed for signaling or tactical disorientation | Runs 3.25 hours

When using two standard CR123A Lithium Batteries:

• High Mode: 1,000 Lumens | 27,100 Candela | 330-meter beam distance | Runs 1.25 hours
