Introduction: Seasonal Challenges for Outdoor Lighting
As summer approaches, high temperatures, heavy rainfall, and increased UV exposure place greater demands on the durability of outdoor IP68 lights. The GL116, a premium stainless steel underwater light, is engineered with 316-grade stainless steel and IP68-rated protection, making it ideal for in-ground installation. Whether facing the humid tropical climate of Southeast Asia, the variable weather of Europe, or the extreme temperature swings of North America, the GL116 stainless steel landscape light delivers unmatched performance year-round.
1. 316 Stainless Steel: The Corrosion-Resistant of In-Ground Lights
1.1 Resisting High Salt & Humidity in Summer
The GL116 stainless steel in-ground light utilises 316-grade stainless steel, which contains 2-3% molybdenum for 3-5x better corrosion resistance than standard 304 stainless steel. This makes it perfect for outdoor underwater lights in coastal areas, such as pools, fountains, and seaside landscapes.
1.2 Withstanding Extreme Temperature Swings
Seasonal transitions can subject buried lights to temperature fluctuations from -30°C to 60°C. The GL116’s low thermal expansion coefficient (16.0×10⁻⁶/°C) and austenitic structure prevent seal failure due to thermal stress, ensuring long-term reliability.
2. IP68 Protection: Defying Storms, Dust & Long-Term Submersion
2.1 Fully Waterproof, Unaffected by Heavy Rain
As a true IP68 underwater light, the GL116 can operate continuously underwater at depths of up to 2 meters for 30 days, far exceeding the IP67 standard of typical outdoor in-ground lights. Its multi-layer sealing (silicone gaskets + laser welding) ensures complete dryness inside, even during heavy downpours or accidental submersion.
2.2 Dustproof Design for Sand & Debris
With an IP6X dustproof rating and a unique "labyrinth cooling channel," the GL116 stainless steel light maintains optimal heat dissipation while blocking sand, pollen, and other particles. North American users report 98% cooling efficiency even after Arizona dust storms.
3. Advanced Thermal Management: Stable Performance in Summer Heat
3.1 3D Cooling System
- Aluminium housing for stainless steel light with radial cooling fins (45% increased surface area)
- High-thermal-conductivity aluminum PCB for direct LED heat dissipation
- Smart temperature control reduces current by 5% at >50°C to extend lifespan
3.2 Weather-Resistant Materials
- UV-resistant polycarbonate lens (prevents yellowing)
- Aerospace-grade silicone seals (-60°C to 250°C)
- UL-certified potting compound (flame-retardant & anti-ageing)
4. Winter Performance: Ensuring Year-Round Reliability
4.1 Cold-Start Technology (-30°C)
The GL116 submersible in-ground light features a pre-heating circuit for reliable startup in extreme cold. Field data from Helsinki shows zero failures over three winters (-28°C minimum).
4.2 Anti-Freeze Structural Design
- 12% expansion buffer space in housing
- Drain valve prevents condensation buildup
Optional 3W heating module (for Arctic climates
5. Globally Proven Stainless Steel IP68 Lighting
5.1 European High-End Projects
- CE, ENEC certified
- Hamburg Harbour Boardwalk: 300+ GL116 lights, zero corrosion after 4 years
- Swiss Alpine Spa Hotel: Stainless steel underwater lights operate 14 hours daily in snow/hot spring conditions
5.2 Meeting North America’s Strict Standards
- UL1838 certified, complies with California Title 24
- Survived Florida hurricane testing (54 m/s winds)
- Quebec freeze-thaw test: Maintained IP68 after 200 cycles
Conclusion: GL116 – Redefining Outdoor Underwater Lighting Standards
From stainless steel pool lights in Southeast Asian resorts to frost-resistant in-ground lights in Nordic cities and outdoor IP68-rated lights in North American villas, the GL116 sets a new benchmark with:
✅ Low maintenance
✅ -30°C to 60°C full-range performance
✅ Versatile use in landscape, safety, and decorative lighting
