I can send a signal to turn it off, but a few seconds later it's on again. Well, you may have a ghost if other strange things are happening. If that s the case, I can t help and would suggest burning down the place. Actually, this is a common question for our tech support team members.

Most aquarium lights use fluorescent bulbs powered by ballast transformers.
The fluorescent light should give you some idea where the problem is centered. Now don t get defensive about fluorescent lights, I like them too, and for some applications, they are a great source of lighting. The problem is the ballast transformer that drives the bulbs. This unit will convert the 120 volts of AC voltage to some higher voltage that powers the bulbs. The primary component of an electromagnetic ballast is a core of stacked steel laminations surrounded by wound coils of insulated wire.
