Thats fine seedlings don't need very much light, t5s are perfect. when they become bigger you could probably add more light depending on how many watts of light you have. I vegged 4 plants under like 125 watts of t5 for a small cfl grow and they grew nicely.
edit: make sure you the light is close enough to the seedlings to they don't stretch, i'd say like a foot away or so... maybe even closer if you would like.
