T/UNP 758-2025 Water feature with LED lights

Scope

Main technical content: This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of light-emitting diode (LED) lamps for water features (hereinafter referred to as "LED lamps"). These include Class III protection against electric shock, an operating voltage not exceeding AC/DC 12V, and rated power ranging from 5W to 90W. The wiring troughs must be smooth and free from burrs, and the LED modules must be reliably fixed. The wiring terminals and other components must comply with relevant standards. The mechanical strength must withstand a 0.7N·m impact, and the anti-corrosion and UV radiation performance must meet the specified requirements. The dustproof and waterproof performance must reach IP68, with an insulation resistance of no less than 1MΩ and minimum values for creepage distance and electrical clearance. After endurance testing, the LED lamps must operate normally for more than 15 minutes, with power not exceeding 110% of the rated value, a power factor of ≥0.9, and specific requirements for optical performance such as luminous efficiency and light transmittance maintenance rate. These LED lamps are suitable for use in water features, musical fountains, waterfalls, and fountains, but are not suitable for use in places where humans come into direct contact, such as swimming pools and bathrooms.
