When it comes to industrial lighting, two terms that are frequently used interchangeably are vapor proof lights and vapor tight lights. However, these terms refer to two distinct types of lighting fixtures. In this article, we will discuss the differences between vapor proof and vapor tight lights so that you can choose the best lighting solution for your needs.
Vapor Proof Lights
Vapor proof lights are designed to withstand harsh environmental conditions, particularly those with high levels of moisture and humidity. These lights are commonly found in outdoor locations such as parking lots, docks, and construction sites. They can also be used in refrigeration units and other areas with extreme temperature changes. Vapor proof lights are enclosed in a seal-tight fixture that prevents water and dust from entering and damaging the light fixture. The seal-tight fixture also keeps moisture and corrosive fumes away from the light source, preserving the lifespan of the bulb.
Vapor Tight Lights
Vapor tight lights are designed to protect against not only moisture but also against gases, fumes, and vapors. These lights are commonly used in chemical plants, wastewater treatment plants, and other locations with high concentrations of corrosive chemicals and gases. Vapor tight lights are also designed to be completely sealed, but they use a different type of gasket around the fixture's perimeter to prevent gases and fumes from entering.
Key Differences
To summarize the differences between vapor proof and vapor tight lights:
- Vapor proof lights are designed to protect against moisture and dust.
- Vapor tight lights are designed to protect against moisture, dust, corrosive gases, and fumes.
- Vapor proof lights can be used in outdoor locations with extreme temperature changes, while vapor tight lights are typically used in industrial settings with high concentrations of corrosive chemicals and gases.
- Both types of lights are designed to be completely sealed, but vapor tight lights use a different type of gasket to prevent gases and fumes from entering.
Final Thoughts
When choosing between vapor proof and vapor tight lights, it's essential to consider the environment where the lights will be used. If you need lighting fixtures in areas with high moisture but not necessarily corrosive gases, vapor proof lights may be the right choice. On the other hand, if you need lighting in an industrial setting with harsh chemicals and gases, vapor-tight lights may be required. In any case, choosing the right lighting will help ensure safe and efficient operations.
