Jetbeam E26 Kunai Review: A Flat EDC Flashlight With a Few Smart Touches

Introduction

Flat-style EDC flashlights are everywhere right now, and the Jetbeam E26 Kunai is the brand’s very first attempt at the format. It borrows heavily from the Olight Arkfeld Pro, and the resemblance is hard to miss: a slim aluminum body, a side switch surrounded by a rotating mode dial, and the same trio of white light, UV, and green laser modes. Where it breaks away is the addition of a tail switch and a mechanical lockout, two features that genuinely improve everyday usability.

The E26 claims a maximum output of 2,000 lumens, a 165-meter max throw, 6,800 candela of peak intensity, and up to 65 hours of runtime on low. It is available in orange, black, and green, and there are two versions: this one with a white LED, UV, and green laser, and an alternative with dual white LEDs.

Who This Flashlight Is For

Jetbeam markets the E26 as an EDC light, and the format supports that. It measures 5.24 inches long, 1.26 inches wide, and 0.63 inches thick, weighing 4 ounces (114 grams) on the scale. The flat body with ribbed sides feels secure in hand and carries comfortably in a pocket, helped by a stainless steel pocket clip with good tension. It is not a deep-carry clip, so roughly an inch of the light sits above the pocket edge, but the slim profile keeps it manageable.

If you want a single light for pocket carry, occasional utility tasks, and the occasional UV or laser party trick, the E26 fits. If you need serious throw, deep pocket carry, or ultra-low moonlight levels, other lights will serve you better.

Main Strengths

The standout feature is the mechanical lockout built into the rotary dial. A convex side switch can easily be pressed accidentally in a pocket, and a dedicated lockout position on the dial is a smart, effective solution. The Arkfeld Pro offers only a button-press lockout, and in our view the mechanical version is far more convenient.

The tail switch is another genuine positive. It is rubberized, nicely clicky, and gives instant access to turbo and strobe. You can grip the light underhand or overhand, and the tactical tail switch behavior is exactly what you want from that format.

Inside, a 1,700 mAh built-in lithium polymer battery charges in about an hour through the USB-C port. The UI is easy to learn: rotate the dial to white light, UV, or laser, press the side switch once to activate, and press and hold to cycle brightness levels. The light remembers your last brightness level when you return to a mode.

The white light itself is a highlight. Powered by a single Luminus SST40 LED behind an orange-peel reflector, it produces a warm, slightly floody beam with a soft hotspot that suits everyday carry work far better than the harsh cool white of many competitors. Mode spacing is sensible: 15 lumens on low, 300 lumens on medium, 700 on high, and 2,000 on turbo, plus a full-power strobe.

Build quality is decent overall. The aluminum alloy body with a Type III hard anodized finish looks excellent, the paint job is clean, and the light carries an IPX8 rating (submersible in up to 6 feet of water), 1.5-meter impact resistance, a scratch-resistant optical lens, and a 5-year warranty. Four zirconium beads integrated into the bezel act as a glass breaker, though with almost no protruding bezel, using it that way risks damaging the lens.

Things to Consider Before Buying

The rotating dial and side switch are the biggest disappointment. The aluminum dial and button feel loose, rocking visibly under a thumb and rattling when tapped. Compared with the smooth, solid rotation of the Arkfeld Pro, it makes the E26 feel cheaper than it should.

Other caveats worth knowing before you buy:

• There is no moonlight or firefly mode, and no direct access to low. A 15-lumen low is useful, but a half- or one-lumen floor would make this a much better EDC light.
• The tail switch cancels the previous mode. Press it for instant turbo, let go, and your white light, UV, or laser setting is gone, forcing you to re-select it.
• The green laser is weak. Compared directly with the Arkfeld Pro, the E26’s 520 nm Class 3R laser is barely visible in daylight.
• The exposed USB-C port has no cover or rubber flap. The IPX8 rating suggests an internal seal, but with dust proofing untested (the “X”), pocket lint and debris can still find their way in.
• High and turbo output measured below the claims on an independent sphere test: roughly 580 lumens on high and around 1,400 to 1,430 lumens on turbo versus the claimed 700 and 2,000. Turbo also steps down rather than holding its claimed 1.6-hour figure. Take these readings with a grain of salt, but expect some shortfall.
• Turbo heat is manageable rather than extreme: a two-minute run reached around 117 degrees Fahrenheit at the head and roughly 100 degrees on the body, warm but comfortable without gloves.

Buying Advice

At around $87, the E26 Kunai undercuts the Olight Arkfeld Ultra (around $120) and sits below several pricier alternatives in the same flat-light category. For buyers who want the flat format with a tail switch and mechanical lockout, it is a genuinely good value.

That said, it is not on the same level as the Arkfeld Pro or Ultra in fit and finish. If dial wobble, a weak laser, and the missing moonlight mode bother you, it may be worth paying more or waiting for a refined second version. If you mainly want a warm, comfortable EDC beam with instant turbo access at a lower price, the E26 makes sense today.

Conclusion

Jetbeam’s first flat flashlight gets the important things right: a useful mechanical lockout, a satisfying tail switch with direct turbo and strobe, a warm and floody beam, and solid core build quality with IPX8 sealing and a 5-year warranty. The loose dial, absent moonlight mode, exposed charging port, and underwhelming green laser keep it a step behind the format’s benchmark. At its price, though, it is an easy recommendation for anyone who wants a feature-packed flat EDC light without paying flagship money.
