I have five 4-foot fluorescent fixtures on the bottom of my MV, and some fluorescent blacklights inside, and I haven't had any durability issues. I have those clear plastic sleeves over all my bulbs to contain them in case of breakage, which makes the fluorescents all but disaster-proof. I bring spare bulbs just in case, but have never needed them.
I think fluorescent is a good option, very high light output on pretty low power for pretty cheap.
