I like that you ask what the buyer wants. I realize this may be too late, but I'll say it anyways.
I'd like white moonlights with a built-in photo-cell in the fixture that automatically turns on when it's dark or when the main lights go off. It eliminates the need for a physical switch/separate timer.
I enjoy my moonlights, but hardly ever get around to all the tanks to switch them on.
Thanks for the input! They're already in production though. I will keep you idea for future models. Do you mind the automatic blue lights if they induce algea growth?
