You should put your seeds in some wet cottonwool or some tissue paper in a warm dark place til you see them sprout and then plant em in the soil with the shoot facing down and the shell just a couple off millermeters under the surface. Put em back in te dark warm place till they break the surface and then place em under your light ( a couple of flouresants will be fine untill they have some three fingered leaves).
It is a waste of time using a powerfull light for seedlings when they have no leaves to photosynthasise , seedlings think cool white flouresants are great.

If i were you i would gently move away the soil to see if they have sprouted if they have leave em alone and just put em in the dark till they surface.
