I personally think that the Japanese reverse fuji fluorescent tube fixtures are my number one favorite modern fluorescent tube fixture design.

Here is a video of one such fixture using a rapid start ballast that powers a pair of 2 FLR40S fluorescent tubes:

While looking at the comments made by some of the viewers, some of them noticed a mix of rapid start and preheat fluorescent tube fixtures in the schools that they went to while others noticed a mix of electronically ballasted fluorescent tube fixtures and preheat fluorescent tube fixtures as well.
