ATI Straton X EU
Ultra-slim design, only 9 mm thin
Noise-Free Cooling, absolutely silent
Next-Level Performance, outstanding performance characteristics
Straton X
Revolutionary G3 technology in a minimalist design
Straton X - Uncompromising lighting design reimagined
The passively cooled ATI Straton X, only 9mm thin, sets new standards in the field of LED lighting for reef tanks, uncompromisingly combining the implementation of the most efficient technologies and finest materials in one light – completely without fans, completely without noise.
Ultra-slim / Ultra-flat:

With a height of only 9 mm, the Straton X is probably the flattest high-performance LED aquarium light on the market. Even slimmer and lighter than its predecessors, it blends discreetly into any aquarium design.


Full Aluminum Design:
The Straton X impresses with its precisely manufactured aluminum housing. This not only ensures an elegant appearance but also high stability and durability. At the same time, the aluminum allows for efficient heat dissipation – a crucial advantage for the lifespan and performance of modern LEDs. The Straton X is a true premium product made from high-quality materials, setting new standards in workmanship and design.

Soft Shadow Technology
Even light for healthy corals: Classic LED lights with small, focused light sources often create hotspots – areas with too much light in the center, while areas at the edges are too dimly lit. The Straton X deliberately uses a large surface area with 100 individual light sources, ensuring even illumination across the entire aquarium. This allows corals to receive light from multiple sides, reducing self-shading and promoting healthy, uniform growth.
Next Level Performance,
which is measurable and convincing
Key figures at a glance:
- Absolute Performance - With 1,800 PAR At a distance of 20 cm (8 in), the Straton X delivers light output comparable to direct tropical sunlight. This is made possible by the use of the latest G3 technology, which achieves significantly higher output compared to the previous generation.
- Average area performance: At a practical distance of 60 cm (24 in), the Straton X achieves impressive results on an area of 60×60 cm (24x24 in). 390 PAR on average – and all this with a power consumption of just 150 W.
- Relative Performance: The area coverage results in an excellent relative performance of 2.6 PAR/Watt. This makes the Straton X one of the most efficient LED reef lights in its class.
- SPS 200 area: A PAR value of at least 200 µmol/m2/s is considered necessary for keeping demanding SPS corals – the Straton X achieves this value up to a diameter of 85 cm (34 in), which corresponds to an area of 0.567 m2.
These values impressively demonstrate how efficiently the Straton X, with only 150 W maximum power, enables large-area lighting for various aquarium types.

- PAR-to-price ratio:
A simple wattage comparison in relation to the purchase price is not very informative. What matters is how much usable light is produced per euro invested. Our tests show: The Straton X offers outstanding performance. PAR-to-price ratio and is playing at the very top.
Hybrid Reef Spectrum -
Reef full spectrum with high blue content:
Conventional LED lights typically rely on daylight or blue light. The Straton X combines both: As a true full-spectrum reef light, it flexibly produces any desired light spectrum – from bright daylight to intense blue light. For maximum efficiency, we use the world's most powerful high-power LEDs – selected across manufacturer boundaries to extract the best performance from each color channel. Compared to previous models, the blue light has been further enhanced to accentuate fluorescent coral colors. At the same time, improved white and cyan white tones provide greater overall brightness and more vibrant, striking coral colors.
