*** FAQ:
Q. What's the difference between all the daylight bulbs?
A. HereÂ’s the best way to summarize it:
5,000K = Warm daylight, slight hint of yellow when fired next to a 10,000K. Great for freshwater fish and plant tanks.
6,700K = Nice white, not as visually bright as a higher K bulb. Not as yellow as a 5,000K, also great for freshwater fish and plants.
10,000K = Bright crisp white light.
General Compact Fluorescent Questions:
Q. I don't see a particular color temp (K) or base style (Square / Straight pin) that I am looking for. Can you get it?
A. We stock the most popular color temps and bases available. We also can have a new style bulb made, if demand warrants. Let us know what you're looking for. If we get enough requests, we'll try and source it, or have it made.
Q. My CF bulbs keep breaking, why is that?
A. We'd suspect that your lamp clips are too tight. Stretch them out lightly. The most common breaks we hear about are on the ends of the 2 tubes, where they are connected. This is a fragile area, and it can crack if you are not careful.
Q. What is better, Square Pin or Straight Pin??
A. This is a matter or opinion. But, Square pin is the more popular of the two. Square pin is also a little longer and wider than straight pin, so theoretically, you'd get more surface area that's lighting your tank.
To avoid problems with CF bulbs & ballasts, we recommend:
1) Mount electronic ballasts as far away from heat sources as possible (this would include bulbs as a heat source).
2) Do not mount ballasts in any high humidity areas (ie. above sump, etc).
3) Avoid unnecessarily removing Compact Fluorescent bulbs once they are in place. Glass bulbs are fragile, so take care when handling them.
4) Make sure they are pushed all the way into their sockets.
5) Mount behind glass or acrylic 3-6" above the water. Do NOT operate any bulb directly over exposed water!
6) Securely mount all endcap cords, as loose cords can be pulled on accidentally, resulting in bulb breakage.
7) Most photo periods are between 8-12 hours, depending on specimen needs.
