SPS become darker after one hour !

[Faisal1976us]

Hi ,,,,

Any one can explain to me why my sps become darker after one hour from lights on ! every day when the lights on i have good colors but after one hour from lights on they become darker ! did you think the reason from strong lights
( 3x 400w 14000k and 2 x Vho 140w super actinic for my 150g tank )

maybe the lights are fully warmed up after 1 hr. hence the perceived color shift.
or your eyes adjusting to the halides.. just throwing it out there.
