*** FAQ:
Q. What's the difference between a "Blue 7,100K" and "Actinic 03" bulb?
A. Excellent question! OK, a little background: The original "Actinic 03" bulb was made by Philips. 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. I have both 13W and 9W bulbs on your ballast kits. Why does the 9W look as bright or brighter than the 13W?
A. Remember that the visual eye is a very poor indicator of light intensity. The reason the 9W appear to be so bright is because the physical tube length is shorter than the 13W. Thus, it appears brighter to some.
Q. I bought this light for a "moonlight" type of effect on my tank. How can I dim it?
A. Well, you can't dim the bulb with the ballast kits we sell. But, a popular way to "dim" the light is to go get a white plastic cover for lights at your local superstore. Most people just get one of these plastic covers, cut it, and place it over the light. This then greatly subdues the light, and acts as a light filter.
