Princeton Tec Byte Tactical Headlamp (100 Lumens, Tan)

Let water in from light rain. Also the button doesnt work to turn light on/ off everytime

I have an earlier model (> 5 years old) of this headlamp, and was very pleased with its small profile and red/white light options, so I wanted to purchase a back-up. I took my new Princeton Tec Byte headlamp on a fall backcountry camping trip this month (Oct 2020). Before leaving, I installed brand-new lithium batteries to ensure good performance through cold nights. Unfortunately, after just a few hours of use, the on/off and mode selection switch stopped responding in any sort of predictable way. I could not reliably get the headlamp to turn on/off or cycle between white and red other than in a sporadic and random manner.I cannot image anything vaguely 'tactical' about this product, other than being the sitting duck as you fumble around in the dark trying to get this thing turned on or off. Really disappointed. I discarded the packaging so there's likely no hope of a refund.

Don't know what to say except getting real hesitant buying online anymore. This product was broken on delivery.. Switch not working, and no light turns on. I have tried new batteries to make sure it was not just bad ones. This is a bust for a product and will be returned.

I use this headlamp for low light runs in the morning. The red light filter is nice, but more of a concentrated beam, could be a bit brighter. The white light works quite well to avoid ruts and skunks.

It's bright, it has red light, and it only takes two batteries!
