Princeton Tec Fuel Headlamp Light

Today I’m reviewing the Princeton Tec Fuel Headlamp which I purchased from REI for around $30.

The headlamp has four settings (High, medium, low, and flash) that you cycle through with the single button on top. The headlamp is said to run for 50 hours on high and 146 hours on low (13 Lumens), and runs on three AAA batteries.

There are two main things I like about this headlamp. First is the ratcheting mechanism used to angle the light. It feels well made, it’s easy to use, and can angle from approximately 45 degrees above the horizon to 45 degrees below.

The second thing I like about the Fuel is the elastic headband. Some other headlamps I’ve owned in the past have lost their elasticity over time. I’ve had the Fuel for over a year and it still feels as snug around my head as the first day I purchased it. The material is very elastic, thick, and padded nicely.

On the downside, there is no “night vision saving” red mode on the Fuel. White is all you get. That being said, if white light is all you need, this is a great headlamp.


  • Sturdy ratcheting through every angle from 45 degrees to -45 degrees.
  • Well made elastic headband that doesn’t lose elasticity.
  • Long battery life of 50 hours on high (43 lumens).
  • Single button use for easy operation.


  • No red mode.
  • Battery compartment difficult to open (requires use of plastic piece on band or flat screwdriver).
  • No rubber seals for added waterproofing.
  • My fuel has experienced some minor cracking on the right of the light.
