What is Vapor Tight Lighting?

Posted on

There is a wide variety of commercial lighting fixtures available for both indoor and outdoor applications today. If you’re looking for a dependable lighting fixture for a setting exposed to moisture, dirt, and other elements, you’ll need to consider vapor tight lighting.

In this article, we’re taking a closer look at the benefits, ideal locations, and features of vapor tight lighting.

So, what is vapor tight lighting anyway?

What is Vapor Tight Lighting?

LED vapor tight lights are powerful light sources that are known to be more energy-efficient than traditional High-intensity discharge lamps or metal-halide lamps.

Also, they are durable and can provide light for longer hours, as long as 50,000 hours.

They provide cooler temperatures and burn brighter, which makes them ideal to be left on for an extended period.

For this reason, you get the benefit of protecting your light source as well as the advantage of having a durable, energy-efficient, and cost-effective lighting source.

On the other hand, vapor tight LED fixtures are constructed with a full metal fixture liner that is placed in a reinforced fiberglass enclosure with a high impact diffuser.

The fluorescent vapor-tight luminaire can be constructed using a UV Polycarbonate housing and lens, as well as reinforced snap clips.

Fluorescent vapor tight lighting can also be used in buildings; however, they can add to the electricity cost, yearly.

This is because fluorescent wet location fixtures may require 160 to 40 watts and 192 watts for 4ft fixtures and 8ft fixtures, respectively.

Now, a facility using up 100 of these fixtures might have a huge bill to handle at the end of the month.

Benefits of LED Vapor Lighting Fixtures

Some benefits of using LED vapor lighting fixtures include:

1. Energy Savings

LED vapor tight lighting fixtures can offer a 40% to 60% reduction in the energy they consume in comparison with fluorescent vapor tight Lighting.

For instance, a 4ft LED Vapor Tight Light Fixture has a wattage between 12 to 55 watts, which is considerably lower than the power consumed by other types of vapor tight lighting.

That being the case, thousands of dollars can be saved yearly by adopting LEDs in building instead of fluorescent vapor tight fixtures.

2. Lighting Performance

Bright light is needed in outdoor retail applications and even food processing facilities where high-performance task lighting is used.

On the other hand, LED vapor tight lighting fixtures can provide the needed light and one that is evenly distributed due to its multi-point design.

The same can be said about the wide range of color temperatures LEDs can provide, which gives a range of options when it comes to increasing the visual perception of brightness.

3. Maintenance Cost Reduction

LEDs are unaffected by frequent usage, which makes them more reliable in buildings or facilities where light tends to switch on and off frequently.

Alternatively, fluorescent lamp life will tend to degrade within a short period, if they are turned on and off frequently.

That aside, LEDs are suitable for use in cold environments since they are less likely to be affected by the weather.

A combination of these features makes LEDs durable, and in return, it reduces the maintenance cost that will be required to keep them up and running.

Ideal Applications

There are various locations where LED vapor tight lighting can be used.

Some of these locations include:

1. Parking Garages

Parking garages are usually exposed to weather elements, which makes it needful to use these types of fixtures.

These light fixtures will ensure that the moisture and dirt stirred up by moving vehicles do not enter the fixtures.

If that happens, then it could shorten the lifespan of these fixtures considerably.

Therefore, the benefit of vapor tight LED lighting is to ensure that these lights can withstand any weather.

2. Industrial Food Processing Facilities

Industrial food processing facilities need to be kept clean at all times, and one way that is made possible is by spraying down and cleaning the light fixtures.

On the other hand, there is no need to worry if vapor tight fixtures have been installed, and as such, frequent cleaning will have little or no impact on these lights.

The same cannot be said if regular lights are used in these spaces.

3. Industrial Refrigeration

LED lighting is known to outperform other artificial light sources when it comes to cold temperatures.

In these environments, there tends to be a buildup of condensation on lights.

To that effect, industrial refrigerators, storage, and freezers are better off with LED vapor tight lighting.

4. Shopping Center

Shopping center lighting may also be exposed to rain, snow, and generally cold.

The shopping centers themselves will have people visiting frequently; hence, both indoor and outdoor regions need to be well lit.

A well-lit environment will give shoppers a sense of security irrespective of when they decide to visit the mall.

In the same vein, the security cameras will be able to pick activities to the best detail.

5. Car Washes

Car washes are wet arenas that often have dirt, soap, and moisture that could tamper with the quality of light.

The latter is evident in light discoloration and even corrosion that could lead to the degradation of the fixture.

Vapor tight lighting fixtures, on the contrary, are water-resistant, which helps to preserve the quality of the light.


Vapor tight lighting can help to preserve the quality of your light fixtures, whether they are used in the cold or wet environments.

What’s more, the use of LED lighting fixtures takes it one step further to provide energy efficiency, cost-saving benefits, increased lighting performance, amongst other advantages.

Therefore, if you are looking to save money in the long run, then you need to choose LED vapor tight lighting from a range of options in the market.
