The ULR900 is an architecturally and show-oriented underwater ring light that offers exceptionally rich colors and very powerful light output. The heavy-duty housing is made entirely of pure 316L Stainless Steel, with premium finishing, following our precision engineering principles.
It is available in stunning color (RGBW) or elegant White, and it is full of advanced technologies, intelligent electronics, sophisticated color-mixing optics, microprocessors, internal drivers, and impressively powerful LEDs.
The ⌀64mm (2.5 inches) internal hole of the ring light is sufficient for most fountain nozzles, while the optional threaded accessory [.T] provides a convenient mounting method with 1½” Female threads on either side.

Precision Engineered Stainless Steel.
Heavy Duty Housing.
We are proud to be the first water feature manufacturer to use stainless steel. An innovative decision that we took 4 decades ago has shaped the future of water features for generations of products. Fontana uses only pure raw materials and cutting-edge manufacturing methods: CNCs and Lasers, combined with experienced craftsmanship and thorough testing procedures, following our precision engineering philosophy. These lead to the exemplary product quality, reliability, and performance Fontana lights are famous for.

Super-Smart Technologies
Since the beginning of LED lighting, Fontana has been developing its own LED modules and proprietary technologies. A Fontana luminaire PCB looks like a small computer, because it is a small computer. Taking high-power LEDs to their maximum optimized operating point, Fontana lights offer the highest light output and the most advanced control protocols. Special firmware and hardware protections ensure the longevity of the fixtures, even in the harshest conditions.
Generation 3
Embedded Processor

Color Engine
Dedicated
The embedded microprocessor. It’s a masterpiece of lighting electronics control and the heart of our technology. A technology we constantly refine and improve for longer than 15 years.
The brain of the system constantly monitors the fixture status & temperature, optimizing performance on the fly. It communicates with the controller receiving and interpreting data about ID, color and intensity.
At the same time, the system ensures that data get delivered consistently and intelligent sub-systems keep an eye for possibly improper electrical conditions, blocking off noise and interference.
Advanced Electronics — our best technologies yet. Each Fontana LED module looks like a small computer. The profound attention to detail you would expect of Fontana is evident in every sub-system.
Unparalleled Color Fidelity. The color engine uses high-definition drivers, embedded on the PCB. This method allows for accurate, high-precision and high-fidelity control of each LED.
Famous Reliability. The discrete components of the PCB are carefully selected to meet the strictest quality, reliability and performance standards. The smart self-protections further improve the resilience of the fixture.
led:bus
led:bus is a language. It’s the language that all Fontana lights speak – a technology that we designed from scratch for underwater devices. It’s fully compatible with other languages like DMX, DMX/RDM and Dali. But with led:bus you don’t need to learn anything new, because led:bus is made to work behind the scenes – autonomously and reliably. Led:bus also allows the use of fewer and smaller cables to power and control multiple light fixtures leading to significant cost and resources savings.
With led:bus, all you have to do is connect the cables — and the whole system works by itself. The simplicity of led:bus leads to neater, more organized and manageable installations of complicated systems.
Resources Savings
Interference-Proof
Simple 3-core Cables
You can use simple, non-shielded 3-core cables to power & control multiple fixtures.
Addressable Fixtures
Each light has a unique ID and can be configured to listen to a specific address for multi-color light shows.
Integrated Drivers
The LED drivers are integrated to the module simplifying everything and significantly reducing costs.
Industrial-Grade
led:bus is a heavy-duty, extremely reliable communication protocol. It is encrypted too.
Special versions are also available with Direct DMX/RDM control for universal integration in Show fountains.
Fontana is a formally registered DMX/RDM manufacturer listed with the ID 0965h.
Voltage Drop: Irrelevant. Traditional LED technologies are severely affected by voltage drop. When longer cables are used, the lights further away from the power supply have lower intensity. In some occasions, they might not even work at all.
The Fontana technology is unaffected by voltage drop. Fixtures work at their full potential on any voltage between 12-24V DC (true margins: 10V to 36V DC). Every fixture outputs 100% of its intensity regardless of how far it is from the power supply.
Active Thermal Control
Constant, real-time balancing of Temperature and Performance.
Reverse Polarity
Protected from accidentally incorrect connections.
Voltage Surge
Protected from sudden surges in the circuit voltage.
Flicker-Free
Industry-leading Technology that eliminates flicker at 4.6KHz.
