# LSR Waterproof Gasket For Smart Lighting
---
The LSR Waterproof Gasket for Smart Lighting is a precision-molded liquid silicone rubber sealing component designed specifically to meet the harsh environmental protection requirements of modern smart lighting systems. Manufactured by 橡楚(湖北)橡胶有限公司 (Xiangchu (Hubei) Rubber Co., Ltd.) at our facility in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, this gasket delivers reliable long-term sealing performance for outdoor and high-humidity indoor smart lighting applications.
As a core sealing solution for smart lighting products including landscape spotlights, smart streetlights, bathroom vanity lights, and underwater decorative lamps, our LSR gasket solves common pain points of traditional sealing materials such as aging, compression set, and water intrusion. Made from 100% food-grade, eco-friendly liquid silicone rubber, this gasket maintains stable physical and chemical properties across a wide temperature range, while providing excellent compression resilience to maintain continuous sealing pressure even after years of use.
Our product is compatible with mass production of smart lighting fixtures, supporting injection molding, compression molding, and custom die-cutting processes to match unique fixture designs. It meets IP65 to IP68 waterproof rating requirements when properly installed, making it suitable for almost all smart lighting application scenarios.

Unlike organic rubber or foam sealing materials, LSR has inherent hydrophobic properties, low water absorption, and excellent resistance to ozone and UV degradation. Our gasket maintains consistent compression resilience for over 10 years of outdoor exposure, preventing water intrusion that can damage smart lighting control modules, LEDs, and wiring. It maintains sealing integrity even after repeated temperature cycles, avoiding the hardening or cracking that plagues traditional sealing materials.
At Xiangchu (Hubei) Rubber Co., Ltd., we support full custom molding and die-cutting to match any smart lighting fixture geometry, from round recessed downlight gaskets to irregular smart streetlight housing seals. We can adjust hardness, thickness, and surface texture to meet specific assembly requirements, including self-adhesive backing for quick installation in mass production.
Our LSR gasket is manufactured with non-toxic, addition-cured silicone that meets RoHS and REACH environmental requirements, with no residual harmful solvents or heavy metals. It does not release volatile organic compounds (VOCs) during use, making it safe for residential indoor smart lighting applications as well as public outdoor installations.
The LSR material will not corrode or stain aluminum, plastic, or glass housing materials common in smart lighting fixtures, and it resists adhesion buildup after long-term contact, simplifying maintenance and disassembly when needed. It also provides good buffering and shock absorption, protecting internal LED and control components from vibration damage during transportation and operation.
