The short version
A rechargeable headlamp is lighter and cheaper to run, and when it dies you need a power bank and time. A lamp that also takes replaceable batteries lets you swap in seconds, which matters through a long night. Choose rechargeable for training and short nights; choose a hybrid or carry spares for races with long dark sections.
Common questions
How much light do I need on trails?
More than you think on technical descents and less than you think on smooth trail. Many runners find a moderate beam with good spill more useful than raw lumens, since a narrow spotlight flattens depth perception.
Should I carry a spare light?
For any race with a night section, yes, and most mandatory kit lists require it. A failed headlamp on technical ground at 3am is a genuine safety problem rather than an inconvenience.
Why does my headlamp dim so fast in winter?
Cold reduces battery capacity substantially. Keeping the battery pack under a layer, or carrying spares warm against your body, makes a large difference to burn time.

Choose the Petzl Actik Core Headlamp if…
You have a long night ahead or race in the cold. The ability to drop in fresh batteries when the rechargeable core fades is genuinely useful, and cold weather shortens every battery considerably.

Choose the BioLite Dash 450 Running Headlamp if…
You want the most comfortable lamp for actually running. Running-specific headlamps are built to sit still at running cadence rather than hiking pace, and bounce is what makes a night run miserable.
