I just remembered today, for some reason, the 2x F32T8 rapid start shoplight at my grandmother's old florist. When I was younger I didn't think anything of it, but thinking back that is a really unusual fixture! It had a rather slow rapid startup and two very mercury starved Altos that were basically uselessly bright especially since they were next to a window, but she used them every day and the new owner still does!

Does anyone know just how uncommon a 2x F32T8 RS setup is?
