GTW TAKE
“
Ounce-Counter’s Choice
The Nitecore NU25 UL earns its place by committing fully to weight savings without pretending to be something it is not. This is a purpose-built headlamp for users who plan their nights carefully, manage battery life intentionally, and value grams saved more than runtime overhead. It is not a compromise light. It is a specialist tool that excels when used within its design limits.
Extremely low weight makes it ideal for ultralight backpacking and fast-moving trips
Balanced beam pattern that works well for camp tasks and trail navigation
USB-C rechargeable for simple charging from a power bank
Tradeoff: Built-in battery cannot be replaced in the field
