Review: Streamlight ProTac HL-X

The Streamlight ProTac HL-X is an upgrade to one of my favorite flashlights, namely, the ProTac HL. The HL-X uses either two CR123 batteries or a single 18650 battery (not included). The 18650 battery must be charged outside of the flashlight (does not have charging connector).

The HL-X is on the larger side and sells for $75-$100. The machined aluminum body of the light fits in the palm of my hand and the larger head extends past my palm. This is an extremely rugged tactical light that generates a 1,000 lumen beam with 27,100 candelas. A light of this intensity is more than powerful enough to temporarily blind an attacker. The front and read caps have a semi-aggressive pattern that would be effective if it was used as a striking weapon. The knurled grip area makes the HL-X easy to hold.

  • Construction: The light is machined from aircraft grade aluminum and has a fairly aggressive striking pattern on the head and tail. The threads are tight and very smooth and an O-ring provides additional water sealing.
  • Size: 5.43″ (13.8cm) long, 1″ (2.54cm) barrel diameter, 1.44″ (3.7cm) head diameter. The HL-X is very slightly larger than the Streamlight HL. The HL-X is a bit large to carry in a pocket but easy to carry on a belt. The body diameter is large enough to provide a good grip and the head protrudes enough to provide a good striking surface.
  • Waterproof: IPX7 waterproof to 1 meter for 30 minutes.
  • Durability: Withstands 2-meter drop.
  • Features: High, strobe, low modes, and Ten-Tap programming feature.
  • Light Output: (high) 750 lumens at 18,300 candelas for 1.25 hours, (low) 35 lumens at 900 candelas for 18 hours.
  • Beam Pattern: 48″ x 7″ at 3′ (Beam Scale)
  • Power Fail: No low battery indicator and the flashlight will significantly dime when the CR-123 battery gets to 2.87v.
