• As small as 2 D-cell flashlight. As bright as a car spotlight
• Four light levels from 13 to 630 lumens, plus 4 different strobes
• Advanced Cree four-core LED and textured reflector offers incredible brightness and versatility
• Throws a powerfully focused beam over 300 meters in Turbo mode
• Up to 150 hours of runtime at a very useful 13 lumens

Extreme brightness. Extreme versatility. Extremely affordable. For SAR, exploration, and so much more. The TK40 features an advanced Cree MC-E 4-core LED powered by 8 AA batteries to deliver an amazing 630 lumens, making it the world’s brightest AA-powered flashlight. It’s a light made for adventurers and the adventurous. About the size of a standard 2-D flashlight and just as comfortable to hold. But at 630 lumens, it provides as much light as a car spotlight for two full hours, with a focused beam throw over 300 meters and a very wide, even, surrounding flood. With four brightness levels plus 4 different strobes, and a maximum runtime of over 150 hours on low power (a very useful 13 lumens) this super light offers exceptional performance and versatility.

An affordable choice for any application requiring extremely high output light:

• Search & Rescue
• Wildland firefighting
• Emergency Scenes
• Riot control and tactical operations
• Marine search
• Military
• Industrial
• Aeronautical
• Hunting
• Camping
• Hiking
• Cave exploration
• And many more…

Intelligent design. Intelligent memory circuitry memorizes the last output. So when you activate your light, chances are it will be at the right brightness level when you need it again. Rugged cooling fins behind the bezel help keep the powerful 4-core Cree LED running cooler for the best possible performance. All modes and lighting levels are selected with the single, robust tailcap switch. Even with so many choices it’s surprisingly easy to cycle through to the mode that suits your immediate situation. Indents in the rear cowling make the switch easy to operate, even with gloves, while protecting it from accidental activation Plus it lets the light stand on a flat surface, pointing at the ceiling for use as a room-illuminating “candle.” Its comfortable large diameter and slip-resistant body design make it easy to hold onto under all conditions. The TK40 even includes a shoulder strap for convenient hands-free carry. In hand, or out, this spectacularly versatile light is one you’ll want to hold onto and use for many activities, and many years to come.

Serious durability. The heavy-duty aircraft-grade T6 aluminum body has a durable type III hard-anodized finish that resists dents, scratches, and abrasion. The Cree 4-core LED will never need replacing. And like all Fenix professional grade flashlights, finely machined wear-resistant trapezoidal threads and O-ring seals make the TK40 waterproof to IPX-8 standards.
