The HS40 is a powerful headlamp as well as a versatile tool lamp. It utilizes a powerful SST40 LED to
provide a nice beam for working, running, hiking and more. Powered by one 18650 battery and featuring a
simple but elaborated user interface, HS40 is your reliable partner for every day use.
Safety Instructions
 HS40 is a powerful headlamp. Never point the beam directly at a person, animal or moving vehicles.
Doing so could cause retinal damage. Please do not allow children to play with it. Strobe mode may
cause seizure in persons with photosensitive epilepsy.
 Operating the headlamp for a long time in Turbo or High mode will warm it up. And to protect it from
over-heating, it steps down lower mode automatically. This is normal.
 HS40 is intended to be used with an 18650 rechargeable battery.
 When installing the battery, make sure the anode (+) side always faces towards the head/LED.
 Unscrew the tail cap half a turn to avoid unwanted activation during transport. It also prevents
the battery from draining while the headlamp is in standby.
 Avoid hitting or dropping the headlamp.
