Collection: LED Vapor Tight & Vapor Proof Fixtures

The primary difference lies in the level of environmental sealing. Vapor tight fixtures (like linear LED strips) are designed to keep out rain, steam, and dust in commercial areas like parking garages or hallways. Vapor proof fixtures (like jelly jar lights) provide a more robust, airtight seal engineered for harsher industrial or marine settings where persistent moisture, corrosive vapors, and fine particulates are constant threats.

IP stands for "Ingress Protection," which is a universal rating system that classifies how well a fixture is sealed against intruders like dust (solids) and moisture (liquids). The rating is given as two numbers:

The first number (0-6) rates protection against solids (like dust).

The second number (0-8) rates protection against liquids (like water). The higher the number, the better the protection. Most LED vapor tight fixtures are rated IP65 or higher, which means they are completely 'dust-tight' (6) and protected against water jets from any direction (5).

Yes, absolutely. An IP65 or higher-rated vapor tight light fixture is the standard, required light for car washes and other high-pressure washdown applications due to its ability to withstand constant water spray and cleaning agents.

Many models are. If you need to adjust brightness, look for fixtures specified as "0-10V Dimmable." This requires a compatible 0-10V low-voltage dimmer switch.

Yes. Because LEDs are "instant-on" and not affected by cold, vapor tight led fixtures are the ideal choice for walk-in freezers, coolers, and cold storage facilities.

An NSF (National Sanitation Foundation) rating is critical for food and beverage processing facilities. It certifies that the fixture is constructed with "splash-zone" safe materials, has no exposed glass that could shatter into a production line, and features a smooth, easy-to-clean exterior that won't harbor bacteria or mold during washdown cycles.

This depends on your environment. Plastic latches are cost-effective and perfectly suitable for standard garages or car washes. However, for facilities dealing with high-acid environments (like dairies), harsh chemicals, or extreme temperature fluctuations, stainless steel latches are highly recommended as they won't become brittle or corrode over time, ensuring the seal remains airtight.

The IK rating measures a fixture's resistance to mechanical impact. In shops with low ceilings or high activity, fixtures are prone to being hit by ladders, tools, or debris. A rating of IK08 or higher means the polycarbonate lens can withstand significant impact without cracking, protecting the LEDs and maintaining the vapor-tight seal.

Many linear vapor tight models are designed for "daisy-chaining." They often feature knockout holes on both ends of the housing, allowing you to run conduit from one fixture to the next. This simplifies wiring for long runs in parking garages or warehouse aisles. Always check the product specifications for the maximum number of fixtures allowed on a single circuit.

Choosing the right length is about balance. 4ft vapor tight fixtures are the most versatile and easiest to install for a single person. 8ft vapor tight fixtures are ideal for large, open spaces like car wash tunnels or large corridors because they provide more light per mounting point, reducing the amount of electrical work and hardware needed for the project.
