| basically,,,corals dont care about the color of light, it is the intensity of the light. the K factor of bulbs is for a few reasons, one, pure visual appearance...what do we like to see..2, the higher K ratings grow less nuisance algaes- major plus!
now the K factor affects intensity, the higher the K factor to less instense the light is..there for you need it up the wattage to get growth from corals with higher K. example- a 175 6500k bulb will give the gorals good growth, but to get the same growth with a 10k you would need a 250 watt bulb, or a 400 watt 20k.

i say this as my best advice to a beginner. do not,,,and i repeat,,,,,DO NOT look at my tank as an example....i have a well practised eye, decades of experience, and a trunkload of failures to allow me to force the issue and get away with things most cannot~
