HQ-F Series provides premium underwater lighting specifically engineered for fountains, pools, hydraulic displays, and architectural water features. Built with marine-grade 304 metal, high-temperature silicone seals, and tempered glass lenses, these lights deliver IP68-rated waterproofing for reliable long-term underwater performance.

The lights combine high-efficiency LEDs with precision optics to produce clear, vibrant illumination. Multiple control options are supported, including single color, automatic multicolor, RGB controllers, and DMX512 protocols, while low-voltage AC 12V/24V operation ensures both safety and energy efficiency. Standardized marine-grade mounting hardware and waterproof cable glands compatible with Ø6–8mm cables simplify installation.

Typical applications include indoor and outdoor fountains, garden landscapes, musical and interactive fountains, reflecting pools, decorative water features, and commercial architectural lighting projects. Available models HQ2509-F and HQ2509M-F feature 9×1W LED arrays in monochrome or RGB (3R/3G/3B), power of 9W, housing diameter of 145mm, height 47mm, and 0.5m cord length.

Installation and maintenance guidance recommends using waterproof junction boxes, verifying seals, applying silicone grease to sealing surfaces, tightening cable glands per specifications, and performing leak tests before submersion. Regular inspections of seals and O-rings, monthly lens cleaning, and annual cable checks ensure optimal performance and maintain the warranty.
