LSR Waterproof Gasket For Smart Lighting

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.

Product Advantages

1. Outstanding Long-Term Waterproof and Sealing Performance

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.

1. Customizable Design for Unique Smart Lighting Structures

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.

1. Eco-Friendly and Non-Toxic Material Formula

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.

1. Excellent Compatibility with Housing Materials

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.

Applications

The LSR Waterproof Gasket for Smart Lighting is designed for a wide range of smart lighting products across multiple industries:

• Outdoor Smart Lighting: Smart streetlights, solar-powered garden lights, landscape spotlights, courtyard wall lamps, and perimeter security lighting. These applications require long-term resistance to rain, snow, UV exposure, and extreme temperature changes, and our gaskets meet IP66 and IP67 waterproof rating requirements for these use cases.
• Indoor High-Humidity Smart Lighting: Bathroom mirror front lights, steam room lighting, kitchen under-cabinet smart lights, and laundry room fixtures. Our gasket prevents moisture and steam intrusion, protecting sensitive smart control modules and LED drivers from water damage.
• Underwater Smart Lighting: Swimming pool decorative lights, fountain lighting, and aquarium smart lights. We offer specialized formulations that meet IP68 rating requirements for long-term immersion in fresh and chlorinated water.
• Commercial Smart Lighting: Recessed smart downlights for shopping malls, office buildings, and hospitality venues. The low compression set of our LSR gasket maintains consistent sealing even when fixtures are opened and closed for maintenance multiple times.
• **Specialized Smart Lighting Explosion-proof fixtures for industrial facilities require high-performance sealing that meets both waterproof and flame resistance requirements, and our UL 94 V-0 rated gaskets meet these application needs.

Selection Guide

Hardness Selection

The appropriate hardness for your gasket depends on your fixture design and assembly method:

• 30 – 40 Shore A: Recommended for applications with uneven housing mating surfaces, providing excellent conformability to fill gaps and compensate for manufacturing tolerances. Ideal for large outdoor streetlight housings.
• 40 – 60 Shore A: General-purpose hardness for most smart lighting applications, balancing compression resilience and easy assembly. This is the most common option for recessed downlights and landscape spotlights.
• 60 – 70 Shore A: Recommended for high-precision fixtures with tight tolerance mating surfaces, providing high sealing pressure for IP68 underwater applications.

Size Specifications

We offer two supply modes to match your production needs:

• Standard stock sizes: For common round smart downlight gaskets in diameters 80 mm, 100 mm, 120 mm, and 150 mm, we maintain small batch stock for quick delivery.
• Custom sizes: We produce fully custom gaskets according to your 2D CAD drawings or 3D models, supporting any shape and size within our manufacturing capability. Minimum order quantities apply for custom designs.

Material Grade

We offer two material grades to meet different application requirements:

• General-purpose grade: For standard indoor and outdoor smart lighting applications, meeting all basic waterproof and aging requirements.
• High-performance flame-retardant grade: For industrial explosion-proof lighting and high-power outdoor lighting applications, with UL 94 V-0 flammability rating.
