Doesn't get much better for $25

Black Diamond has always been my go-to for headlamps.
When my old headlamp kicked the bucket, I knew I could count on BD as a replacement.

For the current $24 price, it's hard to beat. A red light, and two different "white" lights make it a perfect choice for any camper or climber.

I don't really need anything special out of a headlamp besides reliability, and you can certainly find that with any BD product
