Low Weight™: Lightweight components and materials create an almost unnoticeable on-the-body feel without compromising durability.

Steady Beam™: Prevents eye fatigue by maintaining a steady lumen output that does not dim until the battery is very low.

Race Fit™: Conical shape, fatigue free buckles, and limited stretch elastic ensure a snug and stable fit which promotes a healthy and natural breathing pattern.

Stable Ride™: Proportional weight distribution combined with our conical belt shape create  balanced load and a no-bounce ride.

Fatigue Free™: Intuitive settings, large buttons, and quick release buckles. Easy operation for fatigued minds in extreme circumstances.

AutoCool™: Heat dispersing fins mounted in and around the light passively dissipate heat, keeping the light cool and efficient during heavy use.

Widebeam™: Like daylight. Let your eyes roam freely without adjusting between light and dark areas. Even lighting eliminates headaches and tunnel vision.

Enduralight™: Sturdy construction and aircraft grade aluminum provide better durability and improved hot and cold tolerance while reducing overall weight.

2 reviews for Lumen 850 Duo Waist Light

  1. Dandelion Dilluvio-Scott

    I have been using the Lumen 600 for years and recently upgraded to this new version of the 850. As an ultra runner specializing in 100 miler and someone who simply enjoys running all night on my own I have really come to appreciate the illumination ultraspire waist lights offer. This model did not disappoint! I like to use the low or medium setting as my default modes which are plenty bright, but absolutely low how far the high mode can cast light when I’m passing through a region with a higher density of bears or moose. The belt is extremely comfortable and often forget it’s even there. Typically I don’t even take if off until well after sunrise when I’m swapping layers.

  2. TX is hot – run at night Chip

    Where has this been all of my life! Headlamps have a place in this world but the “bouncy” light they give off when running trails is why I tried the 850. I love the broad, steady light it provides – depth perception is so much better. I use it on low or medium, with high reserved for sketchy times. The battery has been great – tested to 4 hours so far. It’s so much more comfortable than a headlamp that I sometimes forget to turn it off after the sun comes up – other runners have to remind me when we pass.
