Common questions

Questions before you buy

How many lumens do I need for an ultra marathon?

There is no universal lumen target: route technicality, pace, weather and ambient light all matter. Compare beam shape and sustained modes alongside maximum output, which is usually available only for limited periods.

How long should an ultra-running head torch last?

It should cover the hours you expect to run at the brightness you will actually use, with a reserve or spare battery for delays. Check the maker’s runtime table at a comparable output rather than using the longest low-mode figure alone.

Is the Petzl NAO RL suitable for ultra running?

Petzl presents the NAO RL for trail and ultra-running, with reactive lighting and a rear battery pack. Its runtime depends on mode, so plan from the lighting performance table and carry backup power if your event requires it.

Are head torches with rear batteries more comfortable for running?

A rear battery can balance weight across the head, as the NAO RL design intends, but comfort depends on fit and personal preference. Try the adjustment system with your usual cap or headwear before race day.

Should I carry a spare head torch for an ultra?

Follow the event’s mandatory kit rules and plan for the full dark section, including delays. A charged spare or compatible battery can provide a practical backup if your main lamp fails or runs down.
