Underwater lights

Our underwater lights are lightweight, reliable and economical to use. Our first lights were developed in 1995, and since then we have delivered around 15 000 lights nationally and internationally. The lights are available in two different formats: Metal halide LED.


Underwater lights are widely used in the aquaculture industry to generate an environment with artificial photoperiod. For many fish species, this process is key to avoiding sexual maturity and improving growth.


Our LED lights are being used in a livestream from our camera showing the artificial reef in Smedasundet in Haugesund, Norway.




Orbit LED light

Steinsvik has developed a new LED light for photoperiod with special features that stand out in comparison to traditional metal halide lamps. Among these features are optimal distribution of light, lower energy consumption, higher luminous efficiency, and a longer service life with a reduced maintenance over time.


Its design is designed in a
robust construction and is resistant to harsh sea conditions. An optimal level of automation provides an effective control of parameters for use, also allowing the individual control of intensity regulation of the lights. The automated control system allows the creation of several programming figures, such as creating a light regime in the software, and everything is controllable from the feeding barge.




  • Easy to install
  • Dimmable light
  • Light spectrum in the optimal range for photoperiod

TwinLight 800

TwinLight 800 is equipped with two metal halide bulbs (2x 400W), which radiate a powerful source of “daylight” color that disperse optimally because of the exclusive TwinLight design. The power switch (ignitor) is built into the two metal halide bulbs.This means that you can connect the light directly to 1 phase 230V power, without a starting cabinet. The light bulbs has a life expectancy of approx. 12  000 hours, where the light still has 70% of its original intensity after approx. 9000 hours.





  • Low weight / easy to handle
  • Reliable
  • Cost efficient
