How to Choose the Right Flashlight

Start with the Job, Not the Specs

The single biggest mistake people make buying a flashlight is starting with lumens. A 10,000 lumen torch is overkill for the kitchen junk drawer and useless for a backcountry hike where runtime matters more than peak output. The right starting question is: what will I actually do with this light?

Our Shop By Use page groups Fenix lights by job — EDC, camping, work, tactical, search and rescue, and more. If you can answer "what will I use it for" in one sentence, that page will narrow the choices for you faster than reading any spec sheet.

Lumens — What the Number Actually Means

Lumens measure total light output at the head of the flashlight. More lumens means a brighter beam, but only at the moment the light is at full output. A few things to keep in mind:

• 500 lumens lights up a parking lot. 1,000 lumens lights up a backyard. 3,000+ lumens lights up a field. Most everyday tasks live happily under 1,500 lumens.
• Turbo modes don't last. Almost every high-output flashlight steps down within 2–5 minutes to manage heat. The "5,000 lumen" headline is real, but it's a burst, not a runtime.
• Lower modes matter more. The 50-lumen low mode is what you'll actually use 90% of the time. Make sure the light has a useful low.

All Fenix flashlights are rated using the ANSI FL1 standard, which means lumen claims are measured the same way across the industry — not inflated marketing numbers.

Beam Distance and Throw

Beam distance is the second number you'll see on every Fenix product page, measured in metres. Under ANSI FL1, this is the distance at which the flashlight produces 0.25 lux — roughly the brightness of a full moon on a clear night. It's the distance at which you can identify objects, not just see a faint glow.

A short, fat reflector spreads light wide for close work. A deep, narrow reflector throws a tight beam far down a trail. Most Fenix flashlights compromise between the two. If you specifically need to reach 500 metres or more, look at the Long Range collection — those models are built for throw.

Runtime — Read the Whole Curve

Manufacturers list runtime per mode. The headline turbo runtime is rarely useful because the light steps down quickly. What you want to know is the runtime on the mode you'll actually use — usually mid or high. A flashlight that runs 6 hours on high will outlast one that runs 90 minutes on turbo for any real-world task.

Headlamps for camping should comfortably run a full evening on mid (5+ hours). Work lights for a job site should make it through a shift. Tactical lights prioritize peak output over runtime — that's the trade-off you accept when you pick that category.

Battery Type

Modern Fenix lights use one of three rechargeable lithium-ion cell sizes (21700, 18650, 16340) or AA/AAA disposables. Each has trade-offs:

• 21700 — biggest capacity, most runtime, most output. The standard for current high-performance flashlights.
• 18650 — proven, widely available, fits a huge range of older and current models.
• 16340 / CR123A — smaller and lighter for compact EDC, shorter runtime.
• AA / AAA — the only option if you want to grab batteries at any hardware store. Fewer high-output models.

For full details on each cell type, see our Battery Guide.

Built-In USB-C vs External Charger

Most current Fenix flashlights charge directly via a USB-C port on the body — same cable as your phone. This is the most convenient option for everyday use and the right pick if you want a single light that's always ready.

If you carry spare batteries (for hunting, search and rescue, multi-day trips), you'll want a model with a removable cell and a separate charger so you can keep one battery on the charger while another is in the light. Many Fenix models support both — built-in USB-C plus a removable cell.

Build Quality and Ratings

Look for two ratings on every product page:

• IP68 (waterproof) — submersible up to 2 metres. The standard for current Fenix flashlights. Some models are IP66 (heavy rain, splash) which is fine for most users but not divers.
• 1 metre or 2 metre impact rating — measured under ANSI FL1, this is the height the flashlight survives a drop onto concrete without losing function.

Body material is almost universally aerospace-grade aluminum with a hard-anodized finish. Lenses are toughened glass with anti-reflective coating. Buttons should be sealed against water and dust.

Switch Type and User Interface

Two basic patterns dominate Fenix flashlights:

• Tail switch — push the back of the flashlight to turn on. Common on tactical lights because you can hold the light in a fist or "ice pick" grip and click with your thumb. Often supports momentary-on (press and hold) for quick checks.
• Side switch — a small button on the head. Common on EDC and headlamps because it stays out of the way in a pocket and supports more mode controls.

Many Fenix models have both — a tactical tail switch for instant-on plus a side switch for mode selection. That's the most flexible setup if you can't decide.

Modes and How Many You Actually Need

More modes is not better. Most people use two: a moderate "everyday" mode and turbo when they need to throw light far or wake up the neighbours. Fenix flashlights typically include 4 to 6 brightness levels, plus strobe and SOS where appropriate. Look for models that start in the last-used mode or have a dedicated "moonlight" low mode (under 5 lumens) for night use without ruining your dark adaptation.

Size and Weight

The best flashlight is the one you actually have with you. A monster 21700 thrower is impressive on the table and stays in the table drawer because it's too heavy to clip to a belt. For daily carry, look at compact 18650 or 16340 models in the EDC collection — small enough to forget you're carrying, bright enough to be genuinely useful.

Headlamp or Flashlight?

Headlamps are better whenever you need both hands free — camping, working under a vehicle, climbing, fishing in the dark. Flashlights are better when you need focused throw to check something at a distance, or when you need to point light independently of where you're looking. Many Canadians own both: a headlamp in the camping kit, a flashlight on the keychain or in the truck.

Budget

You can spend anywhere from $30 to $400+ on a Fenix light. Generally:

• Under $80 — solid keychain lights, basic headlamps, entry-level EDC.
• $80–$150 — the sweet spot. Most Fenix flashlights in this range cover 95% of real-world use cases.
• $150–$250 — high-output, long-range, or specialty (work, tactical, multi-cell).
• $250+ — extreme throw, massive output, professional duty use, or specialty.

Spending more on a light you'll use daily is almost always worth it. Spending more on a backup light that lives in a drawer is not.

Frequently Asked Questions

How many lumens do I need?

For everyday use, 500 to 1,500 lumens is plenty. For outdoor work, search, or long-range use, 2,000+ lumens helps. More lumens beyond what you need just trades runtime and battery life for diminishing returns in real visibility.

What's the difference between flood and throw?

Flood spreads light wide for close-range work like cooking, working on a vehicle, or hiking on a trail. Throw concentrates light into a tight beam for spotting things at a distance. Most Fenix flashlights balance both. Specialty long-range models maximize throw at the cost of close-range spread.

Are Fenix flashlights worth the price?

Compared to budget brands, Fenix lights last longer, hold up to drops and weather, and come with manufacturer warranty support. Compared to other premium brands, Fenix consistently delivers high output and proven reliability at a lower price point. For most buyers, they hit the sweet spot of quality and value.

Can I use a flashlight for self-defence?

A bright flashlight with a strobe mode is a legitimate non-violent personal safety tool. It can temporarily disorient a threat and help you create distance. See our Personal Safety collection for models built around fast strobe access. Flashlights are legal to carry across all of Canada.

Where are Fenix flashlights made?

Fenix Lighting designs and manufactures in China. The brand has been operating since 2004 and is widely used by law enforcement, military, search and rescue, and outdoor professionals worldwide. All Fenix products sold by Canadian Flashlights Supply are sourced through authorized distribution and carry the full manufacturer warranty.
