Giesemann MegaChrome Coral

[Sleepy78]

About a month ago i buyed new light: AquaMedic 2x250+3x54 T5 actinic.
But AquaMedic HQI lamps make my tank some yellow (12000K , but looks like 10000K).

Yesterday I have seen tank with lamps Giesemann MegaChrome Coral 250 watt 14500 K 12500 lumen. It was super ! Good strong cold white light !!! But it was super for my eyses...
Will this lamp good for my SPS and LPS corals ? Will not they become brown ?

Here is spectr of Giesmann lamps:
