Light up the night like never before with the Petzl Ultra Belt Accu 4 headlamp. Modular design lets you carry the battery pack in a pocket while the 6 powerful LEDs throw a stunning beam up to 120m.

  • Belt Accu 4 version of the Ultra includes a 4,000 mAh rechargeable lithium ion battery as opposed to the 2,000 mAh battery that's included with the standard Ultra
  • 51 in. long cable allows the battery pack to be carried in a pocket, keeping the weight on the head to only 8.1 oz.; battery pack weighs 9.3 oz.
  • Ideal for adventure racers and nighttime explorers, the Ultra Belt Accu 4 has 3 brightness settings (low, medium, high) and a maximum light output of 350 lumens
  • Rechargeable lithium ion battery pack provides up to 3 hrs. 15 min. of runtime on high
  • Light automatically switches to power reserve mode when the batteries get low, buying you an additional 45 min. of use on high
  • Light selection dial is easily adjusted while on the move; switch the dial to the lock setting when transporting the headlamp to avoid accidentally turning it on
  • Whether you're reading a map or running a trail, the lighting head pivots from straight ahead to straight down so you can aim the light exactly where you need it
  • Storm-resistant body keeps the light operating in the worst of weather; IP66 rating indicates protection against hose-projected water and complete protection against dust
  • Energy gauge located on the battery pack indicates in bar-graph form how much battery power remains
  • Included battery charger fully recharges the battery pack (lithium ion 4,000 mAh) in only 5 hrs.; charger includes European and American outlet adapters
  • Lithium ion batteries continue to work well at cold temperatures
  • Stretchy side and top straps adjust to securely fit on your head or climbing helmet; front stabilizing plate helps hold the light steady
  • Includes a storage sack
