It does not get more flexible than this
- Housing made of alloyed aluminium only 5 cm high
- Placement of the LED at any desired position
- Completely flexible combination of T5 and LED equipment
- Can be combined with many different LED systems
- 5 different lengths (600, 900, 1200, 1500, 1800mm)
- 3 different widths (optional)
- 4 x 24 / 39 / 54 / 80 Watt T-5
- 2021 newly designed polished individual reflectors for optimum light output

The best of both worlds
With the Giesemann STELLAR you can combine your preferred LED light module for aquarium lighting with two high output T-5 tube pairs. The changeover / upgrade from an existing aquarium LED lighting to a hybrid system is therefore child's play.
Use your existing LED lighting or combine the Stellar with a Giesemann LED aquarium light to provide the best light for your corals.
Stellar 2021
- Newly designed reflectors for even more light output
- Only 5 cm high and thus the flattest system hybrid luminaire on the market
- Powder coated aluminium
- No visible screw connections on the visible side of the enclosure


A successful concept
STELLAR is based on our very successful GEMINI Hybrid, accordingly two groups with a total of four T-5 lamps are operated with VHO ballasts for high output and excellent colour rendering.
Each T-5 lamp has its own reflector. The luminaire body is made of high-quality aluminium and completely powder-coated in iridium metallic or pure white.

Combine your STELLAR with some of the most popular LED modules on the market or with the GIESEMANN PULZAR G3 and other LED light bars.
Each STELLAR is supplied with adjustable brackets, suitable for almost all available LED modules and of course for all GIESEMANN LED modules. Further mounting brackets (may be required depending on the number of LED modules to be mounted) are optionally available.
Flexible mounting
Whether on the wall, lying on the aquarium or hanging from the ceiling - the GEMINI 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 GEMINI HYBRID as a top-mounted luminaire on your aquarium.
