Q. What's the difference between a "Blue 7,100K" and "Actinic 03" bulb?
A. Excellent question! OK, a little background: The original Actinic bulb was made by Philips. They had several models, the Actinic 01, 03, 05, etc. They were not made for aquarium use, but were adopted once news spread about the beneficial aspects of using this bulb over reef tanks. Nowadays, "Actinic 03" has become the marketing term used to identify "blue" looking bulbs. Many bulbs are passed off as "actinic", when they are just a blue bulb.
So, to answer the question, Blue 7,100K bulbs are visually brighter than HelloLights Actinic bulbs. Blue bulbs will NOT fluoresce your animals as well as our Actinic bulbs. Many others sell "actinic", but they are really selling blue bulbs. The phosphors coating the interior of our Actinic bulbs are specially formulated to produce a narrow spike of concentrated violet/blue light. This is why they appear to be more faint than blue bulbs. If you have tons-o-corals, then we suggest going with Actinic 03. Remember, a visual measurement of a lights utility is a poor one.
Q. Will this bulb cause some of my corals to glow?
A. Yes, assuming of course that your corals have the correct pigments (i.e. green). It will also not be as noticeable, since it's not an Actinic only. The 10,000K will wash out some of the visual flourescing, but your little nano friends will be happy you got this bulb!
