***FAQ:
Q. Why do different brands of 10,000K bulbs all have different colors? Shouldn't they all be the same if they're marked "10,000K"??
A. Color Temperature ratings (i.e. "K") is more of a marketing term than a true scientific measurement for color. There are far too many variables when it comes to an accurate "K" rating. Bulbs of the same manufacture can color up differently over time, as the ballast ages. This is why most "K" is used as a reference rather than an absolute. The higher the K, generally the more "blue" the bulb becomes. Sunlight is about 5,500K.
Q. I really like a certain manufacturer's bulb in 10,000K, but I've read a lot about other bulbs lately. Which bulb should I go with?
A. Always ask yourself what's most important to you and your tank specimens. If you are an SPS keeper, and your goal is growth, then we suggest 250W or 400W Iwasaki 6,500K bulbs. If you have lower light corals and want a "deep water" look, then go with a 20,000K bulb. If you want "crisp white", then go with a Ushio 10,000K. Just remember that any new bulb that you have never tried will look different to you, as you've grown accustomed to the previous type. Visual color is a matter of personal preference.
