Night light effects on sps

[robs.mark]

I run my t5's from 7am till 8pm, they dim in and out. 2x 250w halides from 12pm - 6pm.
My question is about the LED ornimental lights i have, they run from 6am till 7am, and from 8pm - 11pm. The tank is only black for 7 hours. Do you think this would have any negative effects on my sps?

The LED are the profilux simu's and are quiet bright (white and blue).

Your tank should be black for at least 11 hours, having moon light wouldn't matter but only if the moon light is really really low wattage ones, the ones on my LED fixture is only 0.1w each and I've a total 8 of them in 2 fixtures.

11 hours? Thats way too much for a main lighting source.. Ornamental lighting plays no part in coral growth. The msg was with regards to color etc...
