I have a 3 year old Panasonic bathroom fan, with light and night light in my bathroom. Installed it because of the Panasonic reputation and very low Sone rating. The fan is so quiet I have to look at the timer to see if the indicator light are on. Last month the flouresent light stopped working, so I picked up a new one. The new one didnt work, so i did some investigating and found out that these fans have their own ballast instead of the bulb having it built in like most CFL bulbs have. I tried locating a new ballast and cant find one anywhere but directly from Panasonic. $90 with shipping! Damn! Looked everywhere and cant find them. Are there any other options for possibly using a universal ballast? Or do I just have to bite the bullet and spend the 90 bucks? My worry is that if the original ballast only lasted 3 years is the new one gonna last only 3 years too? Maybe Im better off in the long run to just replace the whole unit....... Anyone have any experience with these fans can give me some advice?
