Here's a Sylvania Beaverlites F30 striplight that I'm planning to convert to preheat and run my F30T8 lamps in. The fixture is currently rapid start and has a LPF Philips ballast in it.
We have some of these at my school, they were 2XF40, but have been converted to electronic F32s... They flicker all the time, quite annoying at times....
Cool, my school used to use fixtures made by C&M Products (like the one I saved in my gallery) running F34s until they replaced the fixtures with new programmed start F32T8 fixtures. The old ones used to flicker for a good 5-10 minutes when they were turned on.
I love the name "Beaver Lite"!
