Question about Juwel Aquarium HeliaLux Spectrum 1200

For a 350-litre Rio aquarium, it is generally recommended to use lighting that is adapted to its length. The Rio 350 aquarium is 121cm long, so lighting of a similar or slightly shorter length would be appropriate. However, I have no specific information on the exact size required for the HeliaLux Spectrum 1200 in this context. It would be best to consult the technical specifications of the product or contact the manufacturer for specific advice.
