TPI thanks for the update and cautions.
I do note that the lengthy warm-up period is intrinsic to the cold-cathode design. I have cold-cathode lights in the dining room in my stick house and they do that, and also have a purple-pink cast until they warm up.
As I have noted elsewhere, I am extremely happy with the fluorescent fixtures installed by Airstream at the factory in my trailer. They use two F8T5 lamps each.
I am not dissatisfied with the OEM reading lights but they do draw a good deal of power (20W).
