Princeton Tec Apex Extreme Headlamp



Show Description

In situations where your gear can't fail, bring this headlamp. For altitude and cold settings, the Apex Extreme has an external battery box that allows you to keep it next to your body to warm it and preserve battery life. It combines a super-bright 3W LED with a 4-LED cluster for spot and general purpose lighting. The impact-resistant, waterproof design can handle nasty weather, extreme cold and general thrashing.

  • Dual-switch system independently controls long-range spot light and close-range 4 LED cluster.
  • 2 large buttons are easy to operate with thick gloves on.
  • Battery power meter.
  • 5 lighting modes.
  • Regulated output for the first 2.5 hours: runs at (high) 275 lumens for 2.5 hours, then gets dimmer as the batteries drain for the remaining 97.5 hours.
  • Compatible with alkaline, lithium, and rechargeable batteries.
