A. Compact fluorescent fixtures are versatile and can be used in a variety of applications due to the large selection of bulbs. The space-saving design maximizes light output in areas with limited space. They are also less expensive to purchase, operate, and maintain compared to other high light output fixtures. Due to the shape of the bulbs, compact fluorescent light fixtures distribute light evenly across the length of the aquarium to reduce light loss. Compact fluorescent light fixtures are great for fish-only, freshwater-planted aquariums and reef aquariums less than 24 inches deep.

Q. Will I be able to use compact fluorescent bulbs in a standard fluorescent light fixture?

A. No. Standard and compact fluorescent bulbs are not interchangeable. Standard fluorescent bulbs are double-ended, with contact pins on both ends, while compact fluorescent bulbs are single-ended with contact pins only on one side. Each fluorescent bulb type requires a light fixture specifically designed for the respective bulb type. However, there are hybrid "screw-in" mini compact fluorescent bulbs designed to fit incandescent light fixtures.

Q. What's the difference between a straight line and square pin compact fluorescent bulb?

A. Compact fluorescent bulbs are generally available in two distinct contact pin configurations. The four contact pins are in either a straight line or a square configuration. While there is no significant difference between the two bulb types, these bulbs are not interchangeable even if they are the same wattage. A straight pin compact fluorescent light fixture is unable to accept square pin bulbs and vice versa. Bulbs in the straight pin configuration are also referred to as "German-style" or "2G11" compact fluorescent bulbs and the square pin configurations are also known as "Japanese/Panasonic-style" or "10Q" compact fluorescent bulbs.

Q. What does the color temperature of a bulb (Kelvin rating) mean?

A. The color temperature (Kelvin rating) gives us insight to the appearance of the light emitted by the bulb. Bulbs with lower K-ratings tend to produce light that appear "warm" such as reds, oranges, and yellows while bulbs with high K-ratings produce light that appear "cool." Sunlight at noon has a K-rating of 5,500ºK and contains a blend of all the colors of the color spectrum. For this reason, 5,500ºK bulbs are also referred to as full-spectrum bulbs and can be used as a reference point when selecting a bulb based on its K-rating.

Q. What are 50/50 bulbs?

A. Manufacturers take advantage of the characteristic dual tube design of compact fluorescent bulbs and combine two different bulb types in a single high output bulb. These combination bulbs are extremely practical, saving both space and money and also minimizing heat output since a single bulb does the work of two bulbs. Popular among reef enthusiasts are the 50/50 bulbs, which are usually a combination bulb that is half 10,000°K and half actinic bulb. Other combinations include bulbs with two different color temperatures (Kelvin rating) and actinic bulbs with two different wavelengths.
