Dual-Fuel Durability: The Foundation of ProTac Proficiency

Streamlight built the ProTac with a 6000-series machined aircraft aluminum body, anodized in matte black. At 4.25 inches long and just under an ounce of difference between battery types, it’s light enough to forget in your pocket yet rugged enough to shrug off a 2 m drop test. The AR-coated, impact-resistant borofloat glass lens contributes to its IPX7 rating, so a sudden Colorado monsoon won’t leave you in the dark.
What sets the Streamlight ProTac apart is its dual-fuel design: you can slide in a CR123A lithium cell or a standard AA (alkaline or lithium) battery. That flexibility means you’ll never be stranded without juice—road trips, camping, or emergency grab-and-go bags all benefit. Plus, swapping from 350 lumens on CR123A to a still-bright 150 lumens on AA just takes a quick twist and pop.
TEN-TAP programming gives users three distinct mode sequences. The factory default (high/strobe/low) suits tactical scenarios, but if you prefer simple high-only blinding or a steady low-light stroll, one quick tap locks in your favorite. That level of customization is uncommon in this size class, making the ProTac uniquely adaptable for both EDC fans and pros.
The anti-roll head and unbreakable stainless-steel pocket clip round out its core design. No more flashlight rolling off picnic tables—or losing it under your car seat. Streamlight’s attention to these details elevates an already stout build into a daily workhorse you can trust.
Beyond the Basics: Secondary Features You’ll Appreciate

Sure, raw output matters—but so do the extras. Streamlight includes a nylon holster threaded for belt carry. It’s not the sturdiest holster on the market, but it’s serviceable for hiking or law-enforcement duty. The tail-cap switch offers momentary and constant on/off, letting you signal, strobe, or dial in your brightness with one hand.
The ProTac’s weight varies by battery: 2.4 oz with an AA lithium, 2.8 oz with AA alkaline, and 2.5 oz with a CR123A. That marginal difference means you can balance weight versus runtime based on your outing. Speaking of runtimes, dive into the specs and you’ll find over 14 hours on low no matter the cell—perfect for overnight builds or power outages.
On top of that, the serialized housing allows positive identification of your unit—a feature usually reserved for law enforcement or military models. The RoHS compliance ensures you’re not packing hazardous materials, an understated win for eco-minded users. Small touches, but ones that distinguish the ProTac Tactical Light from the competition.
Performance in Action: How Bright Is Bright?

When you hit high on a CR123A cell, you get 350 lumens, a 6,400 candela center, and a 160 m throw. That’s enough to light up a football field end zone from midfield. Switch to AA alkaline, and you still enjoy a hefty 150 lumens and 105 m beam—more than enough for backyard late-night dog walks.
Run times vary: on high CR123A you’re looking at 1 hr 30 min, low for 14 hrs; strobe runs 3 hrs continuous. AA alkaline gives 1 hr 20 min on high, 7 ½ hrs on low, and 3 ½ hrs strobe. Swap to AA lithium and high jumps to 4 hrs 15 min—ideal for weekend backpackers smart enough to bring reusable batteries.
In real-world tests, the LED’s solid-state regulation maintains steady brightness until the last 10% of battery life, avoiding a dim-drift that plagues cheaper lights. The beam’s hotspot is intense but surrounded by a modest corona; perfect for long-distance spotting with enough peripheral glow to keep you oriented.
Daniel’s tip: carry a spare AA cell if you’re logging extended hours outdoors. Even if you’re camping off-grid, the ProTac’s dual-fuel nature means you can liberally trade weight for energy without sacrificing core performance.
Conclusion: Should You Buy the Streamlight ProTac Tactical Light?
If you want a compact, durable, and versatile everyday-carry torch that doesn’t skimp on output, the Streamlight ProTac Tactical Light is a stellar choice. Its dual-fuel design, programmable modes, and rugged aircraft-grade construction set it apart from one-trick single-cell lights. While runtime on high is modest and the holster could be tougher, the overall package offers remarkable flexibility for hikers, first responders, and nightly commuters alike.
