Explore our cutting-edge IP68 waterproof recessed luminaires, smart color-changing systems, and high-durability hardware components.
Shenzhen Alter Light Co., Ltd. is a leading manufacturer in the swimming pool lighting industry. We are not only a production facility, but also an innovation-driven company integrating advanced technology, product development, and quality manufacturing. By focusing on smart design, environmental integration, and structural longevity, we help engineering contractors and global lighting distributors build high-performing, visually striking architectural spaces.
With a highly experienced R&D team and a strict quality assurance department, we are able to provide complete lighting solutions for swimming pools and underwater environments. Our focus is on combining safety, durability, energy efficiency, and modern design to deliver reliable lighting systems for global customers.
All underwater lighting products are designed to meet high protection standards such as the IP68 waterproof rating. Our patented sealing and thermal management technologies ensure long-term stability and safety in harsh underwater environments, eliminating water ingress, thermal drift, and premature LED degradation.
We also offer synchronized color control systems (including 2-wire and smart control solutions), enabling seamless lighting effects across multiple fixtures, making pools and water features more dynamic and visually appealing. Our custom-designed DMX and DALI systems integrate seamlessly with smart home networks and commercial building automation systems.
Shenzhen Alter Light Co., Ltd. serves customers worldwide, with a strong market presence in Europe, North America, South America, the Middle East, and Asia-Pacific regions. Our products are widely used in residential pools, hotels, resorts, public water facilities, fountains, and landscape projects. We excel at translating complex client briefs into deployable lighting hardware.
We welcome OEM and ODM partnerships as well as regional distributor collaborations. Our flexible manufacturing system allows us to support customized designs, private labeling, and project-based lighting solutions. At Shenzhen Alter Light Co., Ltd., we believe in a win-win cooperation philosophy. We are committed to delivering high-quality products, competitive pricing, and reliable long-term service to our global partners.
"High-integrity architectural inground and underwater lighting demands more than simple assembly. It requires deep research into thermal fluid dynamics, polymer degradation under chlorinated exposure, and high-tolerance mechanical engineering. Alter Light bridges the gap between scientific engineering and aesthetic illumination."

LEDs generated in underwater or sealed inground well environments face strict thermal constraints. Without efficient cooling pathways, high junction temperatures accelerate lumen depreciation, causing chromaticity shifts and driver failures. At Alter Light, we utilize marine-grade 304/316 stainless steel housings engineered with integrated thermal chimneys. By conducting heat away from the PCB and into the surrounding water body or substrate, we keep LED junction temperatures below 65°C, ensuring a true L70 operating lifetime exceeding 50,000 hours.
Ingress protection in well lighting requires addressing capillary pressure and chemical exposure. Soil compaction and changing weather cause temperature changes that pull moisture inside through the cable entries. Our fixtures address this using three design strategies: precision-molded EPDM gaskets, chemically cured polyurethane potting that encapsulates the driver cavity, and proprietary high-adhesion anti-capillary cables that prevent moisture from wicking along the copper strands. This ensures stable operation under IP68 conditions.
Modern architectural schemes demand complex dynamic scenarios. While legacy systems required complex 4-wire layouts that increased cabling costs and installation errors, our 2-wire system modulates data directly onto the low-voltage power line (PLC). This enables seamless RGBW transitions, dimming schedules, and customized color profiles over simple, cost-effective wire setups. For high-end municipal installations, our native DMX512 controllers support frame rates up to 44Hz, eliminating visible flicker during video recordings.

How we tailor lighting technologies to meet the strict aesthetic and safety requirements of complex architecture projects.
Public water features, plazas, and city walkways require robust durability. Our drive-over rated inground well lights (IK10) handle heavy traffic and harsh weather, and run on low-voltage (24VDC) for public safety. Precise asymmetric optics project light along vertical surfaces without glare, ensuring clean architectural lighting without light pollution.
For resort hotels, spas, and wellness villas, visual comfort is essential. We offer high CRI (Ra>90) color profiles that bring out the true beauty of natural stone, water features, and outdoor landscapes. By using nicheless installations and flush finishes, our lighting blends seamlessly with pool finishes, keeping the focus entirely on the lighting effect.
Modern luxury homes require reliable, easy-to-use smart integration. Our luminaires connect with protocols like Zigbee, Tuya, and Lutron systems. Homeowners can customize scenes, coordinate pool lighting with landscape paths, and set timing programs right from their phones. Low-profile designs ensure clean, uninterrupted lines during the day.
Shenzhen, China stands as the global hub for optoelectronics manufacturing. As a premium manufacturer here, Alter Light leverages a complete ecosystem of raw materials, metal fabrication, tooling, and component vendors. This physical proximity allows us to go from CAD drawings to fully functional metal prototypes in under 10 business days. Our advanced injection molding facilities, high-speed SMT assembly, and automated potting equipment ensure production speed and consistent quality for orders of any scale.
Our Quality Management System (QMS) uses strict end-of-line testing. Every IP68 fixture is subjected to a simulated 3-bar pressure immersion test, equivalent to a depth of 30 meters. By testing electrical safety, thermal stability, and sealing under load before packaging, we minimize field failures. This direct quality control reduces warranty expenses and protects your brand's reputation.
From purchasing high-purity aluminum alloys to sourcing tier-1 LED chipsets (Cree, Osram, Epistar), every material batch is fully documented for complete trace-and-track control.
Automated gluing and potting systems ensure consistent chemical volumes. This eliminates the microscopic air bubbles and uneven thickness often caused by manual application.
Located near Shenzhen and Hong Kong shipping ports, we offer quick sea, air, and express delivery services with custom export documentation for hassle-free customs clearance.
For international buyers, navigating technical compliance, certifications, and product liability is a top priority. Shenzhen Alter Light supports trade operations with full compliance documentation. Our products conform to EN 60598-1, EN 60598-2-18, and CE/RoHS directives. For North American partners, we ensure all components utilize UL-listed materials and low-voltage standards (UL 676 guidelines for underwater luminaires).
Additionally, we offer extensive support documentation, including detailed installation guides, CAD templates, IES photometrics, and wiring schematics. By supplying detailed engineering files, we help specifiers and engineers get projects approved quickly and minimize installation errors on site.
