Designed for the professional in mind, this flashlight has shock and water resistant epoxy sealed heads with unequaled light output to battery runtime. The twist on/off mechanism is the simplest and most reliable feature in the market today.

The Eiger Ultra X uses Quantum Tunneling Composite (QTC) Technology for variable light output. This allows you to adjust the light output from a dim glow to the brightest single AAA battery flashlight available. The Ultra X is a special version of the Eiger that has a light output 50% higher than the standard Eiger and runs only on a single Lithium-Ion rechargeable battery.

The Eiger Ultra X uses a special optic that more than triples the light throw of the standard Eiger. These flashlights are distinctive by a larger head feature and interchangeable with all standard Eiger bodies.

Because of the ultra-high output, Peak LED Flashlights are for professional use only and thus are not recommended to be used by children. Maximum light output can produce extreme heat and cause eye damage if flashed in face.
