The Tetra LightWave Single Lamp allows you to add a second lamp to the Tetra LightWave Set for optimum illumination of larger and deeper aquariums. All you need is the Tetra LightWave Splitter. The power supply of the Tetra LightWave complete set is already designed to operate a second LED of the same length and power. The high lumen output of the LED makes your aquarium shine with brilliant and natural daylight. In addition, the light spectrum of the lamp stimulates the formation of chlorophyll, which promotes the growth of aquarium plants. Good plant growth is still the best precaution against increased algae growth. In addition to the LED, the kit includes various mounting solutions such as adapters for T5 and T8 fluorescent bulbs, suction cups for glass pane mounting, and clips and screws for mounting the LED in a hood. The Tetra LightWave Timer is optionally available to control the LED with different lighting scenarios such as sunrise and sunset, cloud cover, thunderstorms, etc.
