Summary
Compact, bright, long runtime, two channels for flood and throw, easy to use. That describes the Cyansky HS7R quite well. In addition, there is an integrated charging function and a sensor, which is supposed to reduce the brightness if something is close in front of the flashlight (however dark objects aren’t recognized).
The difference in distance between flood and throw is a bit too small in my opinion, but the flood channel has a pleasant warm white color. A more focused throw channel with the same color temperature as the flood channel would be great. It would also be nice if the mode memory would also work for the higher levels.
As a headlamp, the HS7R would be a bit too heavy for me in the long run. Instead I’d use a lighter headlamp with less brightness and a powerful handheld flashlight like the Cyansky P25 v2.
I don’t think so. If you ignore the stepdowns in my runtime measurement and assume that it can maintain high level all the time, I’d say the total runtime at 800 lm will be more like 3 hours. Which is more or less what you get from the flood channel after the initial stepdown. Turn it on at turbo, wait 30 seconds for the stepdown and then you’ll get almost 3 hours at roughly 750 lm.
