When selecting lighting solutions for industrial or high-moisture environments, it’s crucial to understand the distinction between vapor tight and vapor-proof fixtures. Although the terms are often used interchangeably, they serve different purposes and are designed for different applications.
Let's break down the key differences to help you choose the right solution for your needs.
Vapor tight light fixtures are bright, long-lasting fixtures that provide efficient illumination in large spaces, such as sports arenas, gyms, banks, and outdoor environments. They are designed to withstand challenging conditions, offering consistent and reliable lighting.
Vapor tight light fixtures rely on three key design features, usually aligned with international and industrial IP rating standards, such as IP67 and IP68.
Structural seal: The lamp housing is made through an integrated molding process to reduce the gaps at the joints.
Interface protection: External interfaces such as power lines and signal lines use waterproof connectors, such as PG type and M type threaded connectors. Sealing rings or potting treatment block gap channels at the interface.
Internal protection: Some high-demand airtight fixtures also undergo potting and encapsulation of the internal circuit board and light source module
Vapor proof light fixtures are engineered to prevent moisture, dust, and other contaminants from affecting light quality. These fixtures are often used in environments with high moisture levels, such as kitchens, food service areas, or industrial settings, where standard fixtures might not operate safely. They are commonly used in locations where regular lights would be damaged by exposure.
The construction of a vapor proof light typically involves high-strength materials such as polycarbonate, reinforced fiberglass, or stainless steel. These materials resist corrosion and can withstand long-term exposure to humidity or chemicals. In addition, vapor proof lights are often equipped with shatter-resistant lenses and tightly sealed enclosures. This ensures that the light remains functional even when exposed to steam, splashes, or airborne particles.
The main difference between vapor tight lights and vapor-proof fixtures is the level of protection they provide against environmental factors like moisture and dust. Vapor-proof fixtures offer a more robust seal, ensuring that moisture and dust cannot penetrate the fixture, while vapor tight light fixtures typically focus on providing bright illumination for large spaces without the same level of environmental protection.
Use: Small to medium-sized spaces such as commercial buildings, warehouses, and high-humidity environments.
Benefits: These fixtures are durable and feature a cage-style design, protecting the bulb from physical damage while providing reliable illumination in harsh conditions like high humidity or saltwater exposure.
Use: Installed on ceilings, soffits, or walls, these fixtures are ideal for garages, stairwells, car washes, and airports.
Benefits: These fixtures are available in multiple lengths, offering flexible installation options and an alternative to fluorescent tubes.
Use: Large spaces with high ceilings (18 feet or more), such as hangars, warehouses, and hazardous product environments.
Benefits: High bay fixtures are designed for larger areas, offering powerful illumination and durability in tough conditions.
While many LED vapor-tight fixtures are waterproof, it's essential to check the product’s Ingress Protection (IP) rating to confirm. Fixtures with an IP65 or IP66 rating ensure full protection against dust and water ingress, providing a truly vapor-proof experience.
LED vapor-proof fixtures are specifically designed to withstand moisture and vapor, making them an excellent choice for challenging environments such as food service areas, tunnels, maintenance areas, and parking garages.
For sauna use, it's recommended to choose LED vapor-proof fixtures rated IP68 for steam protection and durability in extreme heat conditions.
Yes, vapor-tight fixtures come in various designs to suit different applications. From the compact Jelly Jar to the extensive High Bay fixtures, each type is tailored to meet specific lighting needs in diverse environments.
Although often used interchangeably, the difference lies in the level of protection. Both types are designed to protect against moisture, but vapor-proof fixtures often meet higher standards. Be sure to check the specifications and IP ratings before making a selection.
Flickering in vapor lights can occur when a sensor detects reflected light or when the light is nearing the end of its lifespan. Ensure the fixture is correctly installed and in good condition to avoid this issue.
Vapor-proof fixtures are essential for high-moisture and industrial environments where safety and durability are paramount. Whether you're replacing incandescent or fluorescent lights, LED vapor-proof fixtures offer enhanced energy efficiency and long-lasting performance. Be sure to consult your building codes and specific environmental requirements to choose the most appropriate fixture for your space.
