I don't think many people actually know this. I know I am going to stock up on bulbs. Lighting is not a big part of my electric bill but I do have a lot of F40s.
My wife's country club is another thing. She doesn't even know how many there are but it is a number. Her electrician is saying that he has a bunch of customers in the same boat and he wonders if the distributors can even source that many ballasts. He is also not sure when he will have time to install them all.
I did see an interesting product (from Leviton I think) at the contractors lunch a while ago.
It is a one piece deal that replaces the keystones and ballast in one shot with a T-5. You just keep the can and lens.
I bet it is spendy tho.
