HQ-SD Series spotlights are premium LED fixtures engineered for underwater and outdoor architectural lighting. Constructed from marine-grade 304 corrosion-resistant alloy with precision silicone seals and tempered glass lenses, these lights provide IP68-rated waterproofing, making them ideal for fountains, pools, gardens, pathways, and landscape accents. Available in monochrome and RGB variants, they deliver vibrant, sharp beams and support DMX512 control for dynamic, synchronized lighting effects.

These spotlights are designed for durability and efficiency. The corrosion-resistant housing withstands harsh environments, while high-efficiency LEDs reduce energy consumption and maintenance costs. Standardized mounting hardware and waterproof cable glands (Ø6–8mm) simplify installation, ensuring reliable performance over time.

Typical applications include residential and commercial landscape lighting, underwater installations, architectural illumination for buildings, tree and fountain highlighting, and professional large-scale DMX-controlled projects.

The series covers models HQ-SD03 to HQ-SD15M, offering LED outputs from 1×3W up to 5×3W, total power 3–15W, IP68 protection, weights from 0.65kg to 1.8kg, and 0.5m cable length. Installation best practices include using waterproof junction boxes, verifying seals, applying silicone grease, tightening cable glands, performing leak tests, and regular maintenance such as quarterly seal inspections, monthly lens cleaning, and annual cable checks to maintain waterproof integrity.
