T8 Fluorescent Tubes are the traditional method used to light aquariums. They are available from a number of different manufacturers, in a number of different colour ranges that can be tailored to your aquarium's requirements. To use a T8 Fluorescent Tube, you need to use an electronic controller (ballast) which provides the power to the tube, which is usually held in place within your aquarium hood using plastic clips. Adding reflectors ensures that you all of the light generated by the tube is directed down in to the aquarium, so they're highly recommended.
T8 Fluorescent Tubes are ideal for less demanding applications, such as lighting a coldwater or tropical aquarium, however they don't have a hugely powerful output making them less effective for planted aquariums or reef tanks, when compared to other lighting systems.
At Aquacadabra, we have a huge range of T8 lighting, including products Arcadia and Hagen, which are suitable for both freshwater and marine applications.
