One ounce. 400 lumens. The headlamp r/Ultralight swears by.
4.7 out of 5 stars (216 reviews)
At just one ounce, the NU25 UL barely registers in your pack. USB-C rechargeable with a warm light option that won't blow out your night vision. The red mode works for late-night tent reading. It's not the brightest headlamp on the market, but gram-counters don't need 1,000 lumens. They need reliable light that weighs nothing. This is that.
