I just bought four T8 fluorescent fixtures for the workshop. They give great light to work by there's one problem though; both Tv's upstairs are getting snow storm interferance. I've tried plugging into different cicuits but no change. They've got electronic ballasts & from what i've Googled I can buy an anti interferance unit for each light for around $20 which basically doubles the cost of the fixtures. I haven't priced up an isolating transfomer yet because this is starting to look like a lot of the "bargains" I usually end up with . The lighting is great but i'm getting a lot of EXTRA flack from the "old lady", who reeaally needs a hobby. If anyone's dealt with this problem I'd appreciate some help. Guess where the fixtures are made !
