I don't grow too many seedlings inside, but I will try a flat or two occasionally. I like to give them 12-14 hours, in order to simulate a spring/summer photoperiod. I grow them close to the fluorescents, with the leaves growing up in between the tubes. They go outside in the spring, when the weather's still mild, and I've never seen any sun damage to speak of. Even if there was, they would quickly outgrow it. If you were putting them outside in the middle of summer it could be different, but they'd still recover.
