I got the 60W version.But all three versions of this company should operate similarly, with only a difference in the number of channels.Since I plan on getting the 140W version, it operates similarly to the 60W version.
I don't know if it's because you have an older version of the light, but smatfarm's lights should have a dark phase after the moonlight phase.The dark phase should be completely lightless.Perhaps you could contact the manufacturer directly

Also I'd like to ask if any of you have bought the 140W version and share how the light performs?
