Vapor Tight - Vapor Tight Lights

Vapor tight lights are robust, weather-resistant fixtures designed to protect against moisture and environmental contaminants. The term "vapor tight" refers to their ability to prevent water, dust, and debris from entering the fixture, which could otherwise compromise its performance and longevity. These fixtures often feature gasket-sealed housings made from corrosion-resistant materials like polycarbonate or aluminum. 

The sealed design safeguards the internal components, making them ideal for use in areas exposed to harsh conditions. Additionally, vapor tight LEDs are more environmentally friendly than traditional lighting technologies, as they contain no hazardous materials like mercury.

The two main types of vapor tight lights are linear Vapor-Tight Lights and Jelly-Jar Lights. Each is designed for environments with moisture, dust, and contaminants.

Vapor tight lights have IP ratings of IP65 or IP66. Both ratings offer the same level of protection against dust but differ in their ability to resist water under pressure. 

• IP65: The fixture is dust-tight and can withstand low-pressure water jets from any direction, offering protection against water splashes but not immersion.
• IP66: The fixture is also dust-tight but can handle more intense, high-pressure water jets from any direction, providing stronger water resistance compared to IP65. However, it is still not rated for full immersion.

While IP65-rated LED light fixtures offer protection against water and dust, they are not always necessarily vapor tight. Check the product specifications to confirm.

Vapor tight fixtures are linear fixtures that feature a gasketed seal to prevent water and dust from entering the fixture and are easily recognizable by the metal latches that ensure a secure closure. These fixtures typically have an ingress protection (IP) rating of either IP65 or IP66.

An IP65 rating means the fixture is dust-tight and resistant to water jets from any angle, while an IP66 rating indicates protection against dust, water jets, and heavy sprays. Vapor tight fixtures can be used in warehouses, loading docks, car washes, and similar environments.

Vapor proof fixtures differ slightly. While they share dust-tight and water-tight properties with vapor tight fixtures and can carry similar IP ratings, vapor proof fixtures also provide protection against vapors, gasses, and corrosive fumes. These fixtures are designed for various applications, including laboratories,  freezers, coolers, laundromats, tunnels, and manufacturing facilities where chemicals are involved.
