Ok, George, perhaps you can explain. Coralife is touting their 10,000K
bulb as being daylight. All of the comments I can find about it indicate
that it is a very bright daylight sort of bulb. However, I have a 7100K
bulb and it is actinic. 5500K is high noon and 6700K is daylight; what
I used to be quite confident that going from a 2700K bulb to a 20000K
bulb was going from yellow to blue. However, all the verbage written about
10-12,000K flourescents and 10-20,000K Metal Halide has me doubting this
previous assumption of mine.
Can you detail this further relating Kelvin temp to CRI and Lux/Lumens or
give a competant, trustworthy source for the info.
