Plug this timer between your M&M PetLight and its power adapter, set the on and off time and your light will gradually turn on and off over a 20 minute period instead of instantly.
Money Saving Tips
If you have multiple cages in one room you only need one light to be on this timer, just make sure your other timers turn on and off while this timer's light is at 100%
If you are a breeder just put one or two linked lights on this timer in a central location in your bird room.
