Tetra LightWave Timer


Tetra LightWave Timer

The Tetra LightWave Timer can be used to control various additional functions.

  • Tetra LightWave Timer enables individual adjustment of additional functions
  • Customised light dimming
  • Sunrises and sunsets can be programmed. The light grows brighter or darker over several minutes to replicate the rising and falling of the sun
  • Cloud scenarios can be programmed to simulate clouds moving across the sky as they would in the fishes’ natural habitat
  • Storm scenarios can be programmed to simulate tropical storms
  • The Tetra LightWave Timer is a particularly good way to replicate your fishes’ natural habitat
Additional product information

Switching to modern LED technology has never been easier. The Tetra LightWave Timer allows you to choose various lighting scenarios to give your fish the most natural light possible. The dimmer function can be adjusted manually and customised to simulate sunrise and sunset. In the sun scenarios, the light grows brighter or darker over several minutes to replicate the rising and falling of the sun. Cloud scenarios are also possible. This creates the effect of clouds moving across the sky as they would in the fishes’ natural habitat. Meanwhile, the storm setting can simulate a tropical storm. In this way, the Tetra LightWave Timer enables fish to be kept in an appropriate, near-natural environment. The timer supplements the Tetra LightWave Complete Set. In contrast to old halogen bulbs or fluorescent tubes, LED lights are energy efficient and consume little electricity. LED bulbs also emit less heat, last much longer and are more environmentally friendly. Unlike old fluorescent tubes, for instance, they do not contain any mercury, which could pose a risk to the aquarium and its inhabitants in the event of a defect. Tetra LightWave combines the many benefits of the timer and near-natural lighting with the advantages of new LED technology. The high lumen value of the Tetra LightWave LEDs brings brilliant, near-natural daylight to your aquarium. Your aquarium plants will particularly benefit from optimised lighting as the light spectrum encourages them to form chlorophyll. In this way, Tetra LightWave promotes plant growth and an intact aquarium ecosystem. In contrast to halogen bulbs or fluorescent tubes, LED lights are also energy efficient and consume little electricity. They emit much less heat, last a great deal longer and are more environmentally friendly. 


Which LightWave size should be used for which tank size?

The LightWave size should be selected on the basis of the tank size and how the light has to be attached. We recommend selecting the largest possible light unit under consideration of these factors. Making the switch to economical yet powerful LED lights is generally always advisable.

For what aquarium size will a single LightWave light suffice and from what tank size are two lights recommended?

To optimally illuminate aquariums, we recommend using two lights from a tank size of 100 litres. The set automatically comes with a transformer for running two lights in parallel.

Is the LightWave light also suitable for plant growth? What needs to be considered?

The colour temperature of the LightWave lights enables optimum plant growth. The chlorophyll in the plants uses the violet-blue light waves for photosynthesis. This produces oxygen and supports the natural biorhythm of the fish.

Is the LightWave also suitable for aquariums with a curved front pane?

Yes. The suction-cup adapter can be used to conveniently attach the LightWave light to the straight side of the aquarium.

What is the voltage of the power supply?

A list of power supply voltages can be found here:


LightWave 270 12V1A
LightWave 430 12V/3A
LightWave 520 12V/3A
LightWave 720 12V/4A
LightWave 830 20V/3A
LightWave 990 20V/3A
LightWave 1140 20V4A


For how long should the daytime lighting be switched on? Are the LEDs dimmable?

Tetra’s LightWave aquarium lighting impresses in many respects, for example through the timer and dimmer functions as well as the sunrise/sunset, cloudy sky and even thunder and lightning effect functions. These optimally imitate the corresponding weather conditions so as to simulate a natural environment where the aquarium’s inhabitants can feel particularly happy.

We recommend having the light on for 12 hours per day to create a regular and natural day/night rhythm.

Can the LightWave light be too hot for smaller or shallower aquariums?

The light’s glass cylinder ensures that some of the heat is already controlled when emitted. As a result, the light’s temperature does not exceed 60°C. This also supports the LED’s durability.

Despite the above, you must ensure that the glass cylinder does not rest on other materials. The adapters supplied are designed to always ensure sufficient space between the light and other materials.

What colour spectrum does the LightWave aquarium light offer?

The LightWave is characterised by beautiful colour rendering. The entire aquarium is brightly illuminated. The light's spectrum simulates natural daylight and therefore also enables photosynthesis to occur.

How durable are the LEDs in the LightWave aquarium lights?

The Tetra LightWave light comes with a two-year guarantee. The LEDs have a service life of approx. 30,000 operating hours.

Why should I switch to LED lighting?

As the service life of LED lights is far longer than that of fluorescent bulbs, switching to LED lighting saves you money. There is also no need for regular retrofitting. Unlike energy-saving bulbs, LED bulbs do not contain any toxic mercury and are therefore more environmentally friendly.

With fluorescent bulbs, what is known as spectral shift occurs over time. This means that the light spectrum shifts, which can lead to it no longer being possible to use certain areas that are important for chlorophyll production. This shift does not occur with LED technology. The spectrum remains the same throughout the service life and ensures optimum lighting for plant growth.
