I have an AviSun light for Bennie. Right now I turn it off or on manually. But I was thinking of getting a timer in case I am away. Right now our routine is that I turn off his light about 1/2 hour before I cover his cage for the night. There is still some light on in the room. After I cover him, I am still in the room until I go to bed. So it is kind of a gradual change from day to night, which is natural. If I get a timer, it would just shut off, making it go from day to midnight in an instant (if it is dark and I am not there). What i was wondering is if there is a timer that would dim the light gradually, even over several minutes. I could just leave another light on in the room so it wouldn't be such an abrupt change.
