Sail Headlamps for Night Watches and Deck Tasks

Red light can reduce the impact of a brief light on dark-adapted vision, though it may not suit every task. Use white light when accurate colour or broader visibility is needed.

Read the maker’s ingress rating and match it to the exposure you expect. Spray, rain and immersion are different conditions, so do not assume a weather-resistant label covers submersion.

Aim the beam down, use the lowest useful setting and consider a red mode for nearby tasks. Avoid shining a focused beam into another person’s eyes.

Rechargeable models suit regular use where charging is reliable. Replaceable batteries can be useful on longer trips; compare the maker’s supported power options.
