The Next-Generation of Explorer Lights, with Quad LEDs. 4x the brightness, 3x the runtime.

Imagine lighting up entire buildings in front of you, all at once, from nothing but a light that fits in your palm!

From shipping containers to airplanes... if you're looking for the ultimate handheld light to see everything at once, the E4K is a perfect fit.

Tiny Quad-LED lights have always been a dream of both engineers and users. At 1000 lumens, each LED needs to output only 250 lumens, so it runs cooler, extending the lifespan of the light.

Literally 4x brighter with 3x the runtime compared to the older generation of lights (compared to a 18650 battery-powered MH12 at 1000 lumen).

Completely sealed without any exposed charging ports, this E4K includes a state-of-the-art 15A, 5000mAh USB-C rechargeable battery.

Combined, you’ve got yourself the most advanced, rugged and ultra-bright light on hand to tackle any kind of job.

All you need to do is get one (or 3) and put it to good use. Just don't blind your teammates in the process.

  • FAST USB RECHARGE - No need for an additional charger. This light comes with a 5000mAh custom battery (NL2150HPR) with built-in USB-C charging port.
  • EASY ONE-HANDED OPERATION - Brightness can be changed with just one button. Press and hold the switch for Turbo or cycle through the 5 brightness levels. It remembers what mode you left it when the light is turned back on.
  • READY FOR ANYTHING YOU ARE - Waterproof and sealed down to 2m, the new E4K can take on any climate. Advanced Temperature Regulation (ATR) technology ensures optimal performance based on the environment temperatures. It goes where you go.
  • 3-WAY NYLON HOLSTER FOR SECURE CARRY- Hang it, strap it, loop it. The holster has 3 ways of mounting, so you can easily get to your light at all times.
