You can manually adjust it so it doesn't gradually get brighter and darker. It has about 6 hours of peak brightness on 24/7 mode. A lot of us here out it on a timer from 6am to about 10 pm so it has a complete blackout. Once it kicks on due to the timer, it stays on whatever mode you left it on. So mine will start on 6am on the 24/7 mode.Hi everyone. Does anyone have this light and if so does anyone use the other functions on it other than the 24/7 mode? I just got it yesterday and I am thinking that the 24/7 mode will not be enough light for my plants. Meaning length of time. Also it never goes completely dark either which in my opinion wouldn't be good for the fish. There is supposed to be a new version Planted 24/7 SE series but has not been released yet. It will have different brackets on it but other than that it appear to have the exact same remote.
The newer 24/7 will be fully programmable, stronger and go completely dark at night. The only thing, it will cost more than the current 24/7.
I'm pretty satisfied with what I mine.
