Elevate your water features with the pinnacle of durability and dynamic illumination. Our SUS 316 Stainless Steel LED Fountain Nozzle Light is engineered specifically for the demanding environment of fountains, water jets, and architectural water gardens. Crafted entirely from marine-grade SUS316 stainless steel, this luminaire offers unparalleled corrosion resistance against chlorinated and salt water. Designed to mount directly onto water jet pipes, it provides powerful, symmetrical lighting that brings water displays to life with vibrant, programmable colors and reliable, long-lasting performance.
Superior Corrosion Resistance: Constructed entirely from SUS 316 stainless steel for housing and accessories, ensuring maximum longevity in harsh, corrosive environments like saltwater and chlorinated pools.
High-Performance Illumination: Features 12 pcs of high-output 2W Single Color Osram or 3W RGB or 4W RGBW LEDs, delivering brilliant and consistent symmetrical light output for stunning visual effects.
Advanced Thermal Management: Integrated overheat sensor (optional) and high-thermal-conductivity silicone sealant effectively dissipate heat, preventing moisture ingress and ensuring optimal LED lifespan.
Robust Waterproofing: Rated IP68 for complete submersion, safe for underwater installation at depths of up to 1 meter.
Versatile Control & Dimming: Supports a wide range of control protocols including standard PWM, with optional DMX512 for professional show control, and dimming via DALI or 1-10V interfaces.
Customizable Aesthetics: Available with standard clear glass or an optional silver-printed finish for a discreet, minimalist look when not illuminated.

Q1: Can this light be used in saltwater environments?
A: Yes. The use of SUS 316 stainless steel, which offers superior resistance to chlorides and saltwater compared to SUS 304, makes this fixture ideal for coastal areas and saltwater fountains.
Q2: Is it possible to control the color and effects of multiple lights simultaneously?
A: Absolutely. For synchronized, complex light shows, you can specify the optional DMX512 control version. This allows you to daisy-chain and individually address hundreds of fixtures from a single controller.
Q3: Why is there a warning against operating the light out of water?
A: The water acts as a crucial cooling medium. Operating the fixture in air for more than 15 minutes can cause it to overheat, potentially triggering the safety sensor (if equipped) or damaging the LEDs. It is designed for submerged operation. As the thermal performance of SUS316 stainless steel is bad, so it is strongly advised to operate it underwater, or operate the Fountain Nozzle Light in the air no nore than 15minutes.
Q4: What is the benefit of the silver-printed glass option?
A: The silver-printed glass helps the fixture blend seamlessly into its surroundings when turned off, reducing its visual impact during the daytime for a more discreet installation.
Q5: What is the expected lifespan of the LEDs?
A: Using high-quality Osram or equivalent LEDs, the fixture is designed for a long operational life of typically 50,000 hours, thanks to its effective heat dissipation system.
