# LSR Waterproof Seal For Smart Lamps
---
LSR Waterproof Seal For Smart Lamps is a precision-molded liquid silicone rubber (LSR) sealing component designed specifically for indoor and outdoor smart lighting applications, developed and manufactured by 橡楚（湖北）橡胶有限公司. As a professional producer of Liquid Silicone Rubber (LSR) products, we engineer these seals to meet the critical requirements of long-term water and dust resistance for smart lamp assemblies, while maintaining stable physical and mechanical properties across a wide range of operating temperatures.
Unlike conventional rubber seals that harden, crack, or degrade after prolonged exposure to outdoor elements or repeated temperature cycling, our LSR waterproof seals leverage the inherent advantages of high-purity liquid silicone rubber to deliver consistent sealing performance over the entire service life of smart lighting products. The seals are molded via precision compression and injection molding processes to achieve tight dimensional tolerances, ensuring a snug, reliable fit between lamp housings, diffusers, mounting bases, and cable entry points, which are the most common leak points in smart lamp designs.
Our LSR waterproof seals for smart lamps comply with international environmental protection standards, are free of harmful phthalates, heavy metals, and volatile organic compounds (VOCs), making them suitable for both residential and commercial smart lighting installations. Whether used in outdoor garden smart lamps, bathroom vanity smart lights, underwater smart pool lighting, or industrial smart warehouse lighting, our seals provide durable, long-lasting waterproof protection.

Our LSR waterproof seals are produced from 100% pure food-contact or industrial-grade liquid silicone rubber, with the following base material properties:
Finished seals undergo full performance testing to confirm the following physical properties:
All seals are produced with controlled manufacturing parameters to ensure consistent quality:

Unlike thermoplastic elastomer (TPE) and general-purpose rubber seals, our LSR seals retain elasticity and sealing performance even after prolonged exposure to UV radiation, rain, extreme temperatures, and atmospheric ozone. They do not crack, shrink, or swell over time, reducing the risk of water ingress and extending the service life of smart lamps, which lowers maintenance and replacement costs for end users.
As an LSR product manufacturer, we offer full customization of size, shape, hardness, and color to match the specific design requirements of any smart lamp, from small bulb-shaped smart lamps to large linear outdoor smart lighting fixtures. Our precision molding processes accommodate complex geometries including irregular cutouts, integrated mounting tabs, and multi-lobed cross-sections to fit all common lamp assembly designs.
All our LSR materials are tested to meet RoHS and REACH environmental requirements, and food-grade options are available for smart lamps used in food preparation areas, residential children’s spaces, and public environments. The material does not release harmful substances even when exposed to long-term sunlight or elevated temperatures, meeting global safety standards for consumer electronics.
The low compression set of our LSR material ensures that the seal maintains consistent contact pressure between mating components even after repeated temperature fluctuations, which is a common cause of seal failure in outdoor applications. This consistent pressure prevents water and dust ingress over the full service life of the smart lamp.

Our LSR Waterproof Seals For Smart Lamps are suitable for a wide range of smart lighting applications, including:
Common mounting positions for our seals include: between the lamp housing and diffuser, around cable entry points, between the mounting base and wall/ceiling, and around the lamp’s control module compartment.

We recommend selecting seal hardness based on your assembly design and application requirements:
We offer custom sizing to match any smart lamp design, with the following common size ranges available:
We can produce seals in any custom shape (round, square, rectangular, irregular) per customer-provided 2D drawings or 3D CAD models.
Select the appropriate material grade based on your application:

橡楚（湖北）橡胶有限公司 operates a quality management system certified to ISO 9001, with strict quality control implemented at every stage of production, from raw material incoming inspection to finished product outgoing testing. Every batch of LSR waterproof seals undergoes performance testing for hardness, dimensions, compression set, and visual defects before shipment to ensure compliance with specified requirements.
Our production facility is located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, where we maintain controlled manufacturing conditions to ensure consistent product quality. We work closely with customers to resolve design and application challenges, and provide full technical support for integration into smart lamp assemblies.
