Bad ass light

  • Familiarity: I've used it several times

Infinitely programmable for brightness (up to 10 different levels in 4 different programs). Produces a heck of a lot of light if needed (335 lumens). It is way more powerful, lasts longer and is half the weight of my wide angle petzl.

Rechargeable battery can be recharged an estimated 300 times. That equivalent to hundreds of alkaline batteries.
