You barely notice the Princeton Tec Byte Headlamp ... until you use it, of course. The low-profile headlamp weighs just over 2 ounces and can pack in whatever sports bag or pack you're carrying, but it packs a punch. The single Maxbright LED emits a concentrated beam that's adequate for the darkest nights and the Red Ultrabright LED allows you to take care of some chores around camp without waking up your buddies or messing with your night vision. The single-arm bracket allows you to securely adjust the angle of the headlamp to best suit the task at hand.

Here's what others have to say...

From the Lab: BYTE

The BYTE headlamp puts out 50 lumens in a spot beam with its two-mode Maxbright LED. A red Ultrabright LED helps you keep a low profile and preserves your night adjusted vision. BYTE is stable with its asymmetrical single arm bracket and the power button is easy to find even while wearing gloves. A new battery lockout prevents accidental battery drain. BYTE runs for up to 146 hours in white mode on just two AAA alkaline batteries. This headlamp is also lithium battery compatible.

Is it easy to replace batteries on this...

Is it easy to replace batteries on this headlamp, (I can do it manually) or does it require a screwdriver to remove the plate to install batteries?

Responded on

After looking at the Byte User Manual, it seems that you do *not* need additional tools to replace the batteries.

Responded on

The Byte is easy to open and replace batteries without any tools.
