My uncle's sps aquarium is lit by 3x 250 mh and 5 x t5's various blues. but the colours of his frags in is his sump are a lot lighter in colour and these are lit solely by 60/40 daylight, actinic t5's. Same water , different lighting . He would like t5's in his display but the aquarium is a funny shape ( wedge like ) so cant get enough above to replace the halides.
