I was just gonna say... seedlings, really? How many seedlings are you growing under the light and how big are they? Like are they fresh sprouts or a good few inches?
88 seems just a touch too hot to me, especially for small seedlings. They might be alright now, but they'll still grow up and you may be surprised how quickly... if the tops get too close it could still burn them and probably wont show until it is too late. At the very least if you're growing in soil\soil-less you are going to find yourself having to water more frequently.
I do seedlings and clones under a 4-tube T5 fluorescent fixture and can do at least 5 plants under it before they get too big (8-12 inches) to make it feasible, without any significant stretching.
