The situation you describe sounds fine to me, even if you stick with fluorescent. With the amount of light you describe, fluorescent isn't a big concern and I wouldn't worry about it. One hour a day of light is close to nothing.
I'm most concerned with people who keep things in an office with bright lights 14 hours a day, or have them displayed in a brightly sunlight room-- the stuff sitting in direct sunlight for 8 hours ever day. And, even then, if they used UV protectant glass or holders, that would still prevent a lot of the damage. Like wearing sunscreen before going out into the Arizona sun.
Cards are a LOT more stable than autographs and photographs. Lithographs (as in Topps, T206s, Goudeys) can fade with lots of exposure, but should stay fine under normal conditions.
