Fluorescent Aquarium Lighting

Fluorescent aquarium lighting is a popular and versatile choice for illuminating your fish tank. It can be used in both freshwater and saltwater applications.

Aquarium fluorescent lighting is the most popular choice for saltwater fish-only systems. High output fluorescent light fixtures, such as T5 lighting, are capable of sustaining higher light demanding SPS corals in reef aquarium systems with the proper reflectors, number of T5 bulbs and using a combination of proper spectrum T5 aquarium fluorescent bulbs. In fact, many successful reef aquariums rely solely on T5 HO fluorescent light fixtures. Compact Fluorescent lights (Power Compact or PC) are another popular style of fluorescent lights.

Aquarium fluorescent lights are commonly abbreviated or written as acronyms. A few to familiarize yourself with include NO (normal output), HO (high output fluorescent), VHO fluorescent (very high output) and V-HO (variable high output). T5 and T12 refer to the diameter of the fluorescent tube in 1/8 inch increments. T5 lights are ⅝ inches across; T12 lights are 12/8 (or 1.5 inches) across.
