Princeton Tec Sync LED Headlamp

An Abundance of Outputs

One of the most versatile headlamps on the market, the Princeton Tec Sync LED Headlamp is sure to cover all your hands-free lighting needs. Winner of the 2015 Backpacker Magazine Editors' Choice Award, this innovative lamp comes with a pair of powerful Maxbright LEDs that together can produce up to 150 Lumens of brilliant brightness while running on just 3 common AAA batteries. The two LEDs each use their own specialized lens to produce a specific type of beam; one uses a crystal clear lens to produce a far-throwing spotlight while the other uses an opaque, micro-textured lens to produce a wider, more evenly dispersed floodlight. The spotlight is perfect for seeing things from far away or lighting up a path, while the floodlight is better suited for illuminating a nearby area like a work station or a campsite. In addition to its duo of Maxbright LEDs, the Sync even features a secondary Ultrabright Red LED that can be used in place of its more intense neighbors to provide less-disruptive illumination that will preserve your natural night vision.

User-Friendly Design

The Sync is about as user-friendly as it gets, with every component designed to make the user experience as simple and convenient as possible. The reliable headlamp is constructed from durable plastics and is sealed tight, making it extremely weather resistant, so you're always ready for what Mother Nature may throw at you. The body is attached to a single arm bracket that allows it to be rotated up and down to provide the user with more lighting angles to fit specific lighting needs. The lamp itself is operated using an extremely straightforward dial switch, featuring distinct markers for each setting including the OFF position and even a lockout function to prevent accidental activation.

Very handy light.

Very impressed with the red light, really strong battery cover clip. Feels like it weights less than my petzl zipka 2.
ConsCouple of minor cosmetic blemishes. None that affect performance.
