Each light is set to its maximum output and then allowed to step down natural. The maximum output for this headlamp is 1,200 lumens. There was still light being emitted for that duration of time.
It would be safe to assume that a battery half the size and power of an 18650 would likely be half of the runtime. Maybe in the future I can run a test on that for confirmation 🤔 😁👍
Hello, you can compare sofirn sp40 with sofirn d25s. Thanks.
I like mine too....great headlamp.
On what lumens did you test the total runtime of 5hrs 59mins?

Time comparison by using 18350 batt?
