Night mode - yay or nay?

[FishyFishy!]

Who turns their powerheads down at night?

I have always left my jebao's night mode on. However i recently made an equipment box that houses all my electrical doodads. Now that the wavemaker (RW20) controller is in this box...its too shaded for the night mode to work. It stays off until i shine a light on it. So now I just turned it off.

Before Jebao's I never did anything at night with my powerheads and everything was fine. So who uses night mode? Any known benefits?

Only downside is that this an RW20, so it does push crazy amount of water. I dont want to stress my fishy friends.
