Please some one advice me: I am having two electronic ballast tubelights that are controlled by one switch. Now, one of them is always getting short circuit. I have replaced 4 of these within one year, none of them lasting more than a month - cause I dont even go to that room regularly. What is the problem? Everything works well for 10-15 days and then it gets short. The wiring is perfect... Is it because of the 2-way system? I'd love to have some help from any of you experts..Thank you !
