Sheer Power.
Incredible Color.

The ULX900 is considered by all means the most powerful underwater light for fountains. It offers record-breaking light output and incredible color richness, amplified by sophisticated color-mixing lenses. Full of tech and smart electronics, it uses our new ULX series housing — a rock-solid, all-stainless steel body made of pure Stainless Steel.

The ULX900 is meant for large-scale WaterShow or Architectural fountains. It performs equally great in stunning color (RGBW or RGBAW) or pure, elegant white. The high-quality and high-clarity light output, combined with the scientific-grade optics, the heavy-duty housing and extensive certifications, make the ULX900 perfect for those high-end, high-profile fountain projects.

Super-Smart Technologies

The ULX900 is packed with tech. The PCB looks like a small computer, because it is a small computer: an intelligent network of heavy-duty electronics, the microprocessor, embedded drivers, firmware and hardware self-protections, and Fontana’s most recent technologies. All work together to deliver the highest light output, stunning colors, and fast communication with the control system — led:bus or Direct DMX/RDM.

LED Module

Fontana Lighting Module Gen.3

Application-specific Fontana LED module, designed for the intended use of the fixture. With embedded microprocessor, embedded drivers, advanced electronics, software and hardware protections. Each module is addressable and can be used with led:bus, DMX/RDM or Dali. Single-color versions require only power supply.



The embedded processor on the fixture constantly monitors the operation of the fixture to ensure optimal operation.

The Active Thermal Protection system uses a smart algorithm to gradually reduce the brightness in case of overheating, ensuring the max. possible light output.

Additional hardware systems provide overvoltage, voltage surge and reverse polarity protection.
