Lighting

[Topreef]

Hi, just in the process to start up a 10g nano (newbie). Will be building up a canopy soon. I have the choice to either go with 4x23w 6,500k daylight bulbs with a pc actinic or go with CSL 96w 10,000K. The first choice is a cheaper way to go, hence my interest, but in the future I would also like trying to keep some sps colonies. Would these grow under the 6,500k or do I have to use 10,000k? I will also set up a refugium, 5.5 gal. Thank you for your reply.
