Lower in Kelvin? Why lower? Just wondering.
the lower the kelvin, the higher the color rendering index (which helps promote growth). heres a description of a 6000k bulb:
This 54 watt 48" Giesemann PowerChrome Midday 6000K German-made T5 high output fluorescent broad spectrum, high CRI bulb encourages coral growth. This T5 fluorescent aquarium lamp is ideally suited to full spectrum use for growth of SPS and also works is great when used in a 1:1 ratio with either the Pure Actinic, or Actinic Plus supplementary lamps.
(from a bulb vendor's website)
problem is, it is so yellow it makes it look like you need carbon
