No, I didn't mean to imply that they should be out for extended periods of time. The problem when we see a burnt out lightbulb is that it might have gone bad just before we saw it. We all know from everyday life is that we never know when a bulb is going to commit suicide. If it is the same ones over a long period of time, no excuse other then with the number of bulbs in the place, how can we be sure that it is exactly the same bulb? Could be another in the same area and unless we stand there and count out the location, we may be right, but, we are really just guessing that it is the same one. My argument is with fixing something that isn't broken. It may still go for years, it may go for a few more days, but, it needs to be spent before it is changed out. It's not the money... we know that Disney can afford it, it is more basic having to do with the resources it requires to make the items. That is the waste and who recycles lightbulbs? We throw them away.
