Product description Function and purpose Submersible LED downlight designed for continuous underwater use. Suitable for inpool, fountain, pond and other wetarea lighting where durable, lowvoltage illumination is required. Key benefits — why you need it Safe lowvoltage operation: Input voltage DC 24 V. When used with the specified lowvoltage power supply and installed correctly, the product meets standards and there is no danger of electric shock when people are in contact. Stable, quality light: Imported LED chips deliver luminous flux and luminous efficiency with no flicker, providing bright, steady illumination and reduced eye strain. Long service life and reliability: Robust components and efficient thermal management extend lamp lifetime and reduce maintenance needs. Easy installation and operation: Designed for straightforward installation in underwater environments. Technical and material highlights Input voltage: DC 24 V (lowvoltage power supply recommended and required for safe underwater use). Lighting source: Imported LED chips for consistent color and brightness. Heat dissipation: Builtin thickened diecast aluminum heat sink combined with a convection design increases thermal performance and helps maintain long service life. Build quality: Firstgrade waterproof construction suitable for prolonged underwater exposure. Performance attributes luminous flux and luminous efficiency for effective area illumination. No flicker — suitable for applications where stable light output is required. heat dissipation to avoid overheating and preserve LED performance over time. Typical applications Swimming pools and spa pools: Permanent underwater lighting that withstands longterm immersion and provides uniform brightness for safety and ambiance. Decorative fountains and water features: Reliable, efficiency illumination for architectural and landscape water installations. Garden ponds and koi ponds: Durable lighting for outdoor submerged environments where continuous operation and good heat management are important. Installation and safety notes Use only with a DC 24 V lowvoltage power supply that meets local safety standards. Ensure proper waterproof connections and follow installation guidelines for underwater fixtures. Regularly inspect seals and mounting hardware as part of routine maintenance to preserve waterproof integrity and performance. This product combines underwaterrated construction, imported LED chips, luminous output, stable (noflicker) performance and a thickened diecast aluminum heat sink with convection design to deliver safe, longlasting underwater illumination.
