The Princeton Tec Byte 100 lumen headlamp provides just enough light to hike at night. The headlamp is lighter and more compact when compared to other hiking headlamps. The white spot light beam allows for more illumination at a distance.

The measured lux values at different distances for the Princeton Tec Byte (100 Lumens) is shown above. At ten feet the lux value is 15 which makes this headlamp useful night hiking. It is important to have a lux value of at least 5 for safe hiking.

Recommended Lux Values

Different tasks require different levels of illumination or lux. In general the more detailed the task the more illumination or lux is required. Detailed drawing work can require 1,000 lux while navigating a stairway at night only requires 15 lux.


The Princeton Tec Byte light distribution

The light distribution of the Princeton Tec Byte (100 Lumens) is shown above. The illumination in lux was measured one foot away from the light. The beam was focused which makes good illumination at a distance possible. Because of the small area of illumination the lux value was high. The measured maximum lux at one foot was 1500 which would make close up detailed work possible.

Summary

Pros

  • Lighter than most headlamps
  • Provides the minimum illumination for hiking at night
  • Has a red LED light option

Cons

  • Low illumination compared to other headlamps
  • Light switch not easy to use
  • Brighter 200 lumen light model weighs the same

The Princeton Tec Byte (100 Lumens) is a lightweight headlamp that meets the minimum requirements for hiking at night under normal trail conditions. The Princeton Tec Byte (100 Lumens) might not be suitable for trails that are not well maintained.  If you plan on using this headlamp for regular night hiking you will likely want a light with better illumination. I recommend upgrading to the Princeton Tec Byte (200 Lumens) for better illumination without adding weight or considering a slightly heavier higher 300 lumen headlamp.

Paul has always liked hiking and thru-hiked the Pacific Crest Trail in 1997 after college. After years of working in chemistry, he wanted to create a career involving the outdoors, so he hiked the PCT again in 2010 to do research for his guide book, Pocket PCT. He realized that creating a smartphone app for navigating the outdoors would make it easier to keep the data current and provide a better way to navigate. While hiking with Ryan (aka Guthook) in 2010, they decided to work together to create the first comprehensive smartphone guide for the PCT.
