Uncompromising light quality

The housing, which is only 4.5 cm thick, is made of high-quality, powder-coated aluminium alloy.

The electronics are thermally separated from the main lighting and the maximum possible reflector surface guarantees absolute area illumination.

All the light is directed into the aquarium without loss and is thus 100% available to your aquarium.

Lüfter der Matrixx II

The flat profile with design elements made of black lacquered glass sets new visual standards in the T5 class.

A compact, high-quality and modern design that can only be found in the Giesemann MATRIX II.

The MATRIXX II has a cleverly designed interior. Ball-bearing, particularly quiet fans support the standard passive cooling of the massive enclosure frame.

This ensures the optimum operating temperature and highest light output for all T-5 lamps. At the same time, the high efficiency guarantees extremely low heat radiation to the aquarium.



The MATRIXX II Dimmtec can be conveniently configured from a Windows PC thanks to built-in App control.

The T5 lamps can be dimmed in groups (combination of 2) from 0-100%. Weather simulation is also possible.

In this way, the day sequences can be individually programmed according to the needs of the aquarium.



As standard, your MATRIXX II luminaire is equipped with the powerful POWERCHROME T-5 lamps in the desired colour combination as well as with fully electronic ballasts that ensure gentle lamp starting with long tube life and complete freedom from flickering.


Flexible mounting

Whether on the wall, lying on the aquarium or hanging from the ceiling - the MATRIX II, made of high-quality aluminium, is as flexible as you want it to be.

Various mounting components allow ceiling or wall mounting or the use of the MATRIX II as a top-mounted luminaire on your aquarium.
