Flourescent Lighting Controllers
Is the main stay for tropical aquariums, the choice of lighting spectrums available allow you to choose lamps that enhance the colours of the fish or to grow plants. Arcadia units are the standard for aquarium starters, they are well specified and very reliable.

Superb light output
• Powerful penetrating white light
• Accentuates natural fish colours
• Colour replicates reef environment

The intensity of the sun around coral reefs is very high. To attempt to replicate this intensity with fluorescent tubes it is necessary to achieve the highest lumen output and the correct spectrum.

Many white lamps are unable to provide the necessary levels of light output combined with the correct colour to really enhance and enliven the appearance of the marine aquarium.

The Arcadia Marine White lamp has a colour temperature of 9,500K (Kelvin) and an exceptional lumen output combined with very good colour rendition. The tri-phosphor formulation provides consistent long life and stability of output at these high levels of performance.

These factors make it the ideal choice for the serious marine aquarist, with excellent levels of light throughout the aquarium and extraordinary clarity for viewing the constantly changing marine environment.

A high proportion of light energy is concentrated in the area between 400 and 480nm, which also assists in the promotion of zooxanthellae production to encourage coral and invertebrate growth.

The other peaks across the spectrum allow the true, vibrant and natural colours of the fish, corals and invertebrates to be enhanced and to really stand out.



To really achieve the best results for marine aquariums, we recommend the combination of Arcadia Marine White and Marine Blue Actinic lamps.This will provide the benefits of excellent light output levels coupled with the correct spectrum to support
symbiotic algae,allowing good growth of the corals and invertebrates whilst greatly improving the overall lighting and appearance of the aquarium, with fluorescent effects as well.

• Re-creates moonlight ambience
• Blue actinic light
• UVA creates fluorescence
• Promotes welfare of invertibrates

For a marine aquarium to realistically represent reef life, it is essential to provide the best conditions for corals and invertebrates to thrive. Most important in this is the survival of zooxanthellae, a specific form of algae, which symbiotically assists the invertebrates to feed and remove waste matter.

In nature, the sun provides over 100,000 luxlux (lumen per sq. metre). At depths of typically 5 to 10 metres, where many of the corals and invertebrates are found, the visible light to be seen, is basically only in the blue wavebands, thus the familiar blue appearance. All the other wavelengths, particularly reds have been absorbed and filtered out by the salt water. This remaining blue light is the light which invertebrates have evolved to utilise for zooxanthellae symbiosis.


The Arcadia Marine Blue Actinic lamp range has been created to provide the specific spectrum (400 - 480nm) necessary to achieve the blue chlorophyll absorption for zooxanthellae symbiosis to develop.

This concentration of light energy in the so called 'actinic' range peaking at 420nm, is essential for the survival and good health of fish, corals and invertebrates in marine aquariums.

Another important element of the Arcadia Marine Blue Actinic lamp is the UV output present, which creates a very pleasant fluorescent effect on corals, invertebrates and exotic marine fish. When used at night with no other lamps, the effect is of a dark moonlit night with the vivid colours of the corals and invertebrates fluorescing brilliantly.

When used in conjunction with the Arcadia Marine White lamp range, the high levels of light output create a most realistic marine reef environment. This combination gives the most natural and pleasant appearance and highlights the fluorescence and bright colours of the fish, corals and invertebrates, along with the correct spectrum output at the required wavelengths to achieve the reproduction of the symbiotic algae, zooxanthellae.

These are the new Marine White lamps from arcadia they offer a T5 version of the spectrum and rendition of there current popular T8 lamp but with the higher output of T5 technology
