EDC Flashlight Guide (2026): How to Read the Specs

How we put this together

Every number below comes from a maker's own page, opened on October 1, 2026. We didn't test any of these lights, and we didn't rank them: a $12.99 AAA keychain light and a $139.95 flat light solve different problems, so the table runs from smallest to largest. Prices are what each store listed that day. Sofirn is missing because its store blocked our check. If "EDC" is new to you, start with what EDC means.

Eight EDC flashlights compared

Price sources: Olight and Wurkkos on their own stores, Nitecore on its official U.S. distributor's store (Nitecore Store), Fenix at Fenix Store, which calls itself the original authorized U.S. retailer. Olight's $54.99 to $94.99 is its Baton 4 page's range; the top price is the Premium kit with a charging case. Wurkkos marked the FC11C down from $36.34.

What the spec numbers mean

The terms on a spec sheet come from ANSI/PLATO FL1, the US standard for flashlight performance claims. Peli's summary gives the definitions (Peli), and Streamlight publishes a one-page version (Streamlight).

• Lumens: total light output in every direction.
• Candela: peak beam intensity, the brightness of the hottest spot. It doesn't change with distance.
• Beam distance: how far away the beam measures 0.25 lux, which Peli compares to full moonlight.
• Run time: counted from the output 30 seconds after switch-on until it falls to 10% of that.
• Water: IPX4 is splash, IPX7 is temporary immersion, IPX8 is continuous immersion on conditions the maker states.

Lumens don't tell you how far a light reaches

Lux is candela divided by distance squared, so a 0.25 lux beam distance works out to 2 × the square root of the candela. The makers' own figures fit. Olight's manual lists the Baton 4 at 7,225 cd and 170 m, Streamlight lists the Wedge XT at 1,900 cd and 87 m, and Nitecore lists the TIP3 at 2,117 cd and 92 m and the EDC37 at 44,010 cd and 420 m. Each pair matches the formula within a metre (our arithmetic). The consequence is that doubling reach takes four times the candela.

That's why 1,300 lumens can reach 170 m (Baton 4) while 1,700 lumens reaches 357 m (PD35 V3.0). By the same formula, 357 m implies roughly 31,900 cd, over four times the Baton 4's 7,225 cd on 1.3 times the lumens (our arithmetic). Makers say what they tuned for. Nitecore describes the TIP3's TIR lens as giving "uniform and soft light," while Fenix credits the PD35 V3.0's de-convex lens and small-caliber reflector for throw.

The EDC37 needs a footnote. Its page lists 8,000 lumens as max output, but its FAQ quotes the 420 m and 44,010 cd for the 3,000-lumen SEARCH mode. Read lumens and distance as two answers, and check which mode each belongs to.

The figures are the maker's own

Olight's manual says its data were "tested per ANSI/PLATO FL 1-2019 standard in Olight's labs for reference." Fenix says its E12 V3 figures come from lab tests with an AA alkaline cell at 21 ± 3 °C and that real performance varies. Output also isn't constant: Wurkkos says the FC11C's Turbo steps down after 90 seconds to prevent overheating.

Water ratings

Fenix states the E12 V3's IP68 as 2 m for up to 30 minutes, an example of "conditions the maker states." Nitecore lists the EDC37 and TIP3 at IP54, which is splash-level.

Pick the battery first

• AAA or AA. Olight's i3E EOS page stresses its "widely available AAA battery," and the E12 V3 takes a standard AA. Output stays modest, at 90 and 200 lumens here. One catch: Fenix says rechargeable 14500 lithium-ion cells, which are AA-sized, are not supported in the E12 V3 and are "banned — do not use." Read the manual before putting any rechargeable cell in an AA light.
• 18650. The rechargeable cell behind the FC11C and PD35 V3.0, and the route to 1,200 to 1,700 lumens in a hand-sized light. Charging differs. The FC11C has a USB-C port on the light and charges without removing the cell. On the PD35 V3.0 the port is on the included battery, and Fenix says the light itself isn't directly rechargeable.
• Built-in or charged in the light. Nitecore lists the TIP3 and EDC37 with built-in batteries, and the Wedge XT's lithium polymer cell charges inside the light in 6 hours, per Streamlight. The EDC37 takes 18 W USB-C and about 2 hours. In all three you charge rather than swap.
• Flying. The FAA says spare lithium-ion batteries go in carry-on baggage only, terminals protected, and airlines may be stricter (FAA).

Switches and lockout

Specs don't show what happens in a pocket with your keys. Five of the eight advertise a lockout: the Wedge XT (FIVE-TAP), FC11C (four clicks), TIP3 (semi and full lockout modes), Baton 4 (press and hold) and EDC37 (Rapid Lock). Fenix's FAQ says the PD35 V3.0 has no lockout and suggests unscrewing the tail cap in storage. The i3E EOS has no button, since you twist the head, and the E12 V3 lists a single tail switch and no lockout.

Small flashlight picks by size

Keychain, 30 g or less. The i3E EOS is about as simple as it gets: one AAA, a twist head, 90 lumens, $12.99. The TIP3 trades the AAA for a built-in battery and 720 lumens at 30 g, and Nitecore lists three color temperatures (3,000K, 4,500K and 6,500K).

Light pocket, 50 to 75 g. The Baton 4 packs 1,300 lumens into 52.5 g and 63 mm, and Olight says the Premium kit's 5,000 mAh case gives up to 190 days of max runtime. The E12 V3 is a $29.95 AA light with a magnetic tail and clip. The Wedge XT is a thin 4.25 in light with two modes, 500 and 50 lumens, and no price on Streamlight's page, which has a dealer locator.

Hand-sized, 110 to 200 g. The FC11C is the cheapest route to 1,200 lumens here, with an 18650 included and about 110 g with the cell per Wurkkos. The PD35 V3.0 buys throw, 357 m, at 134 mm long. The EDC37 is a 108 × 39.3 × 31 mm slab with an OLED readout and the highest output, but only IP54.

EDC flashlight brands

• Olight. Its about page says it was founded in 2007. Our two Olights are the AAA i3E EOS and the rechargeable Baton 4. Olight vs Nitecore goes through the two brands head to head.
• Nitecore. Built-in batteries and high output dominate our picks (TIP3, EDC37). Its U.S. store describes itself as the official U.S. distributor, based in Austin, Texas.
• Fenix. Fenix Store says Fenixlight Ltd began making lights in 2001. We include an AA and an 18650 model.
• Streamlight. The Wedge XT has two modes and a five-tap lockout, and its page lists no price.
• Wurkkos. Says it was founded in 2019 and is based in Shenzhen. The FC11C is the cheapest 18650 light here.

One or two lights per brand is a sample, not a verdict on the brand.

A short checklist before you buy

1. Where will it ride: keychain, pocket or bag? That sets the size class.
2. Which battery will you keep charged or stocked: AAA/AA, 18650 or built-in?
3. Do you need reach or a wide beam? Compare candela and beam distance, not lumens.
4. Does it lock out? Pocket carry makes this matter.
5. Will it get wet? Match the IP rating to the weather.
6. What's the runtime at the mode you'll use daily?

A flashlight handles the dark. For the rest of the pocket, there's an EDC pen, and there's echoPi, which is in development: an EDC fidget slider built around clicks you can program, with seven real clicks as a design target and a note that can play on each one. Join the list if you'd like to hear when it's out.
