LED Vapor Tight Lights - An In Depth Guide

LED Car Wash Lighting

What are vapor tight lights?

A wet environment poses unique lighting challenges during lighting design and installation. Areas with exposure to high humidity, dust, extreme cold, and water need more than an average light, they need vapor tight lights.

Vapor tight lights provide lighting in harsh environments where ordinary light bulbs fail. LED vapor tight lights are the best waterproof lighting there is. They provide protection, reliability, and save energy while delivering high-quality lighting.

These lights are perfect for:
-  kitchen food prep areas
-  car washes
-  parking garages
-  industrial refrigeration spaces
-  areas cleaned with hoses

The terms waterproof and tri-proof describe all lights with an IP67 or higher rating. Vapor proof LEDs are not bulbs though, they are full fixtures made for harsh environments.

These LED lights are durable; they need little maintenance even though they are in wet areas. They can mount vertically as ceiling lights as well. They have a full metal fixture liner that's inside a reinforced PU or fiberglass casing with a high impact diffuser. This ensures that no vapor or moisture outside the bulb enters inside it.

Types of Vapor Tight Lights

Low bay vapor tight lights are perfect solutions for large indoor spaces like food processing facilities or cold rooms. They replace older lighting technologies and provide safe, powerful light. These sturdy lights usually feature IP66 or IP67 rating. They can either suspend or mount on ceilings.

Dirt, dust, or water jets will not damage LED low bays that are vapor proof. They rinse out with water when dirty. They are high-quality aluminum alloy which makes them corrosion resistant. They also have poly-carbonate lenses that can withstand scorching temperatures and corrosive chemicals.

Halogen and metal halide lamps do not fare well under these conditions. They need constant replacements because they are not as durable as LEDs. Low bay vapor tight lights are perfect for spaces that have ceiling heights of at least 12-20 feet.

They are perfect to disperse the light at those heights. They offer high-quality illumination, safety, and an excellent working atmosphere to the users. LED lights are already energy efficient and pair with dimmable features further efficiency.


Linear fixtures are perfect for long spaces such as large rooms or hallways. There are 2 ft, 4 ft, and 8 ft-long fixtures that are waterproof and ideal for use in wet, dusty, and damp commercial spaces. LED vapor proofs for food manufacturing facilities are NSF splash zone rated for use in food service areas.

These lights can also have high impact, frosted or clear lenses to enhance their lumen output. LEDs mounted on linear strip fixtures are ideal for overhead task lighting. They are perfect for canopies, hospitals, cold rooms, and car wash tunnels. Even outdoors where water and dust pose a challenge to traditional lighting modes.

Magnetic Strip Retrofit Kits convert existing vapor proof and vapor tight fixtures from fluorescent tubes to magnetic LED strips. Installation is simple and quick. Remove the old ballast and bulbs. Next, wire the led driver to the input wires and snap in the led strips. Connect them to the driver with the provided quick connects.

Car Wash Lighting and Its Challenges


The simple act of flipping on a switch in a car wash facility goes a long way in attracting your customers. Well-lit locations look safer and often land themselves the biggest customer share. Dark, poor illumination, and shadowy car washes tend to keep customers away.

Drawing customers to your business after dark sets in can bring in massive profits. A car wash has to be open when its customers need it the most. Sometimes, it's the best time to have their cars washed late in the evening or at night, once they are done with their day. For a safe and effective car wash to operate it needs reliable, high-quality lighting.

Good lighting is a brilliant and inexpensive form of adverting for car washes. A well-lit place tends to catch the attention of drivers since it looks professional. It looks safe and inviting to all those who drive by. Providing good lighting is one thing car wash owners can do to boost their market share.

Well-lit areas can also direct your customers’ interest to other services like vending areas and vacuum stations. But, illuminating a car wash can be one long assignment. There are many lighting needs all challenged by the working conditions of a car wash.

Car washes are a wet area with water and humidity. There is steam, mist, high-temperature water, high pressure soap, and even agents such as hot wax. Extreme weather conditions can compound these challenges. It affects the lifespan of the light fixtures used in these facilities.

These extreme conditions can take a toll on the lights. Resulting in frequent maintenance and expenses cutting into profits and operating times. High-quality lighting outside of a car wash can increase business by generating interest. The real magic happens inside the tunnel where the quality promised is delivered.

Traditionally, car washes have relied on IP67 rated fluorescents and metal halides for indoor /outdoor applications. Metal halides are energy inefficient, losing their light output in very short periods.

For example, a 250-watt metal halide lamp, producing 23,000 initial lumens will be producing 14,333 lumens in less than a year. In the end, the business owner will pay for the energy the bulb draws but receive a paltry 40% light output in return. These lights are very wasteful in their use of power.

Metal halides also tend to build up the heat they generate within the light fixture and lens. Eventually this 'bakes' residue from the wet, dusty, moist, soapy, and waxy components in the car wash. This causes a depreciation of light. Needless to say, the constant maintenance to keep the lens clear will cost you in downtime.

Florescent light is also challenging in a car wash, it falters when temperatures get too cold. The lights will definitely need constant replacements. Since they contain mercury, they will pose an environmental challenge during disposal. The toxic substances can present a health risk to your employees, too, if the lights happen to break.

A fluorescent bulb’s cathodes degrade each time it is turned on. To make them last longer, it is imperative that they are not turned on and off frequently. The downside here is that you will end up using more electricity by keeping the lights on longer. Or, you will have to do constant bulb replacements. Add this to the fact that most fluorescent vapor tight light fixtures have 1-4 lamps... and the money you spend adds up.

Benefits of LED Vapor Tight Lights for Car Washes

  • In a car wash, the powerful water jets spray soap, water, and dust directly onto the light fixtures. LED wet location fixtures can withstand this assault. They are very suitable for wet, damp, and dusty locations. Traditional glass and plastic fixtures will degrade when exposed to high pH presoaks. The lenses fade or crack while the glass will etch and become cloudy, compounding the problem of poor lighting.
  • They have a long lifespan and last for over 50,000 hours, which roughly translates to 8 -10 years of usage. LED vapor tight fixtures outlast traditional lighting technologies. Their life expectancy is up to 10 times longer (for LEDs with a rated life of 100,000 hours).
  • LEDs can help you to decrease your car wash's energy costs by up to 75%. They use less power than other lighting because they run cool and generate very little heat. This means they don't waste energy. They use only a tiny fraction of what traditional bulbs use to produce light.
  • Installing vapor tight LEDs in a car wash make the colors pop. White walls appear brighter and vehicles look cleaner and glossier after a wash. LEDs have a high CRI (color rendering index) range of 80-98, which is close to the sun's CRI of 100. This gives their light a daylight appearance. Gone will be the dingy, dark tunnel of old and you will have a more inviting, crispy-white, bright tunnel. This benefit alone is worth the investment that goes into LED waterproof lights. The LEDs also improve the facility's light cost. Utilizing half the power traditional lighting fixtures use.
  • LED lighting fixtures also integrate with electric lighting controls. This helps save more energy and provides increased lighting convenience.


Industrial Refrigeration Lights Challenges

LED Lighting for Cold Storage Warehouses

Commercial refrigeration uses up 7% of all the electricity consumed by retail buildings in the United States. Refrigeration costs can end up comprising more than half of a building's energy costs.

Older refrigeration facilities have for a long time relied on metal halides and high-pressure sodium bulbs for lighting. But these sources of light consume a lot of energy while giving off a lot of heat into the refrigerated space.

Individual cold rooms have to be kept at optimum temperatures to ensure that obligations to all parties on the supply chain are adhered to. With energy costs increasing by the day, it has become imperative to find energy efficient solutions.

Many facility managers and business owners usually pay for projects like better insulation of doors and buildings, load decrease or system optimization, but often forget the contribution that light sources add to the energy inefficiency equation.

LED lighting offers excellent opportunities to enhance energy efficiency, drastically reducing the high costs that heat generated by lighting brings about. Because energy released into a refrigerated space has to be removed by the refrigeration system, the wattage of light sources used in cold rooms has to be taken seriously.

The majority of heat given off by HPS or MH lamps is usually absorbed into the environment or re-radiated, and since these lights are practically on all the time, the impact can be shocking once the math is done.

A 400W HPS light bulb will require 465W to light up – thanks to its ballast. Each fixture may have a cluster of bulbs, and if a facility has a round figure of 100 bulbs, the total lighting power required will be 46.5kW.

These bulbs will put out 158,658 BTU/hr, and most of this heat load will require removal through the refrigeration system. This means that the facility will need to remove 1.25 BTUs of energy per year, purely as a result of lighting. This energy is enough to melt at least 4,3000 tons of ice!

HID lamps and fluorescents are ill-suited for dimming controls or occupancy sensors, features that could slow down energy consumption. HIDs also have long warm-up and restrike periods and putting fluorescents on and off on demand shortens their life cycles. This usually calls for frequent relamping schedules and creates other safety hazards as well.

Benefits of LED Waterproof Lights for Industrial Refrigeration Facilities


  • LED vapor tight lights have made great headways in commercial cold storage facilities. Some facility owners opt for retrofits while others full fixture replacements. Light emitting diodes provide significant energy efficiency in focused light, energy reduction, and thermal load reduction.
  • They are energy efficient, require low wattage to give off high-quality lighting, and are controllable. They also have instant strike times and operate optimally in chilled environments. Their long lifespans of up to 100,000 hours make them cost effective for large commercial spaces.
  • LED vapor tight lights also do well with the high moisture and condensation levels found in refrigeration facilities. They have gasketed seals that prevent water penetration.

Industrial Food Processing Facilities and Their Lighting Challenges

The food processing industry has protocols, which if ignored, could cause catastrophic results. Food facilities have to be both productive and safe and keep food contaminant-free. The regulations on light fixtures in the food processing industry are some of the most stringent.

The lights have to withstand harsh cleaning procedures; they have to be corrosion resistant. And apart from high-pressure washdowns with corrosive cleaners, there is steam, oil, grease, and freezing temperatures – depending on the type of food processing.

The lights used in these applications should have no toxic materials. To ensure that food is free of bacterial growth, spoilage, and to prevent contamination, the quality of lights play a central role. NSF International sets stringent manufacturing standards for light fixtures. Light manufacturers can’t get the certification without following the rules and regulations.

Different areas in a food processing facility have their own set of lighting specifications. Light fixtures for food processing areas must tolerate mist, grime, dust, water, steam, and other contaminants. They also need to withstand constant washdowns with high pressure water jets.

NSF Certified Splash Zone lights have the right design and materials. They meet manufacturing standards. They must also meet the required IESNA (Illuminating Engineering Society North America) levels for individual tasks.

The USDA Food Safety and Inspection Service Manual also gives regulations for various lighting levels in different food processing plants, and specifies the required CRI for some areas.

Benefits of LED Waterproof Lights for Industrial Food Processing Facilities

  • LED vapor tight lights have an advantage over traditional HID and fluorescent lights. They have no breakable materials such as glass that could contaminate food.
  • Their light efficiency and output stay high in low temperatures of cold rooms. They last for more than 50,000 hours and have no toxic components in them.
  • With LEDs, you can integrate a wide range of intelligent light controls. They provide instant illumination, unlike the older, slower bulbs. Employees in food processing facilities don’t have to wait for the lights to warm-up to carry out their tasks.
  • The versatility of LED vapor tight lights meet all the lighting requirements. They enhance safety and lower energy and maintenance costs.

3 Essential Considerations for LED Vapor Tight Lights

The Light Output

The first mission of vapor tight lights is to illuminate the space that needs light. In the past, the illumination quality of a light bulb was measured by how many watts it consumed. The higher the wattage was, the brighter it would be.

Things have changed and today lumens are all that matter as far as light output is concerned. A lumen measures the light output of a light source regardless of its energy consumption. A high number of lumens usually indicates that the bulb is bright.

The IIESNA recommends that illumination levels for food inspection areas range between 30 and 1,000 foot candles, depending on the task. Color grading areas, on the other hand, should have levels of 150 foot candles.

Food handling areas need a minimum of 55 foot candles because safety here is paramount. Cold rooms and storage areas need less lighting because of the lower activity. And for cold rooms, there is a need to let in as little heat as possible.

Light level or illuminance is the measurement of the quantity of light dispersing over a specific work plane. A work plane is where tasks are performed. Illuminance measures in lux or foot candles (FC). A foot candle is equal to one lumen of light density per one square foot. A lux is equal to a lumen per square meter. Your LED waterproof lights should meet the required levels for food handling areas. As well as cold rooms where they will be installed.

For car washes, many owners will gravitate towards too much light rather than too little. Full daylight has about 1,000 FC. An overcast day, has about 100 FC. It is only very intricate work that requires 1,000 + FC.

Brighter lights may be necessary for busy areas since there are other lights competing with yours. For car washes in low population areas, the foot candles can be lower since there are no competing lights. They also give a business a professional look.
Other factors determine the required lumens. Such things as wall colors, the size of rooms, the mounting height of the lights, or the objects in the room. So, a good rule of thumb is to talk to a LED professional to determine the foot candles you need in your application.

Recommended light levels for a car wash

Minimal FC Standard FC Brighter level FC
Vacuum bays and arches 25 35 45
Detail shop 35 45 55
Wash bays and tunnels 60 75 90
The Color Rendering Index

LED vapor tight lights for food processing plants, those used in food handling sections, should have a minimum CRI of 70 as recommended by the United States Department of Agriculture and the food and Drug Administration.

LED Color Rendering Index (CRI)

What is CRI?

CRI is the acronym for color rendering index. It describes how a light source reveals the color of an object to the human eye. It also considers the subtle variations in color shades under a light.

CRI is measured on a scale of 1 to 100, depending on the accuracy of a light source at color rendering when compared to a reference source. So, higher CRI values mean better color rendering abilities. A light source with a CRI of 85-90 is considered good at color rendering. A CRI of 90 or higher shows an excellent color rendering ability.

LED vapor tight lights have high CRI values by design. They are perfect at mitigating risk and enhancing visibility. They help workers to locate items and defects much better than traditional bulbs. LEDs have excellent CRI values of up to 98 and they emit light that is almost like the light emitted by the sun at midday. With LED vapor tight lights, your facility will be inline with the regulations in the food manufacturing industry.

Waterproof LED lights last in the wet and humid car wash environments. They will also make the facility's colors pop and make it more inviting to users. The color temperature can create an inviting ambiance. A color temperature of 4000K to 6500K will make it brighter and will reduce eye strain for the workers.

The IP Rating

The International Protection Marking (IP Code/Ingress Protection) rates the effectiveness from intrusion like dust or water. The IP rating is a standard of International Electrotechnical Commission (IEC). It applies to a wide range of products.

It is of utmost importance that you verify the IP rating of your LED vapor tight lights before you get them. The IP rating ensures that specific lights can be used without becoming a safety hazard to the users. A light's IP rating reflects its suitability for outdoor or indoor use.

The “I” in IP refers to the protection level the light's enclosure. It protects its internal components against solid particles. The letter “P" referes to the ability to protect its internal components against water.

Waterproof lighting is essential where light fixtures have exposure to moisture, water, dust or oil. Food processing plants wash with high-pressure hoses. This which expose the light to corrosive cleaning agents and water splashes.

Light fixtures in commercial refrigeration will face condensation, wet conditions, and extreme cold. A car wash light will have to withstand extreme wet conditions, harsh cleaning agents, and hot wax. Lights installed in warehouses have pollution and dusty environments that could cause damage.

This is why a LED fixture’s IP rating is so critical. It tells us exactly the electrical components protection. A higher IP rating signifies greater protection against the intrusion of smaller particulates. A lower rating points to a limited protection against such intrusions. The highest rating indicates that the fixtures are protected and can submerge in water without any damage.


Second Digit IP Rating (Protection Against Liquids)
Level Particulate Protected Against Further Directions
0 None
1 Dripping water Vertically falling drops
2 Dripping water when inclined at 15° Vertically falling water at angles of up to 15°
3 Water spray Water sprays at angles of up to 60° vertically
4 Water splash Water splashes against the enclosure shall not damage the light fixture
5 Water jets A 6.3 mm nozzle projecting water at the chassis from any angle shall not damage the fixture
6 Robust water jets A 12.5 mm nozzle spraying powerful water jets towards the enclosure shall not do it any damage.
7 Immersion up to 1 meter The light fixture can be immersed in water under defined pressure and time (up to 1m of water)
8 Beyond 1m of immersion The manufacturer of the lighting fixture will specify the conditions of submergence. This lighting fixture is hermetically sealed.

What IP Rating Should You Choose For Your Vapor Tight Lights?

A vapor proof light has a rugged, die-cast outer casing that protects its wiring and lamp socket from corrosive fumes, moisture, dust, and gases. It is usually installed where an ability to handle these hazards matters.

These lights are popular in:
- laundry facilities, swimming pools, car washes,
-food processing facilities, stairwells, subways,
-riding arenas, automotive repair centers, barns,
-parking garages, commercial refrigeration facilities,
-kitchens, and bakeries.

These are environments where the fixtures have exposure to dirt, wetness, and dampness. Regular lighting fixtures will present a safety risk to the users.



Vapor tight light can withstand water sprayed at it by a 0.25-inch nozzle, regardless of the water's direction. This light fixture is protected against such water jets and foreign bodies and works in the outdoors.



Waterproof light fixture can withstand water sprayed at it from a 0.50-inch nozzle from any direction.



Provides total protection against dust. It can be submerged in 15 cm-1 m of water. IP67 rated fixtures also offer total protection against dust and can be submerged in water deeper than 1 m for long periods of time.



LED lights with these ratings are completely protected against dust and can be fully immersed in water deeper than 1 m for an extended period of time.

3 Reasons to Choose LED Vapor Tight Lights

They Have Excellent Construction to Withstand Harsh Conditions


Vapor tight lights are also known as wet location fixtures. With gaskets and sealed luminaires for wet indoor and outdoor environments. The light fixtures install in areas with a considerable amount of water, dust, and humidity.

The gasketed seal around the lens also protects from corrosive fumes, non-explosive vapors, or gases. If you use fixtures that are not vapor proof in these harsh conditions, you will ruin their wiring. In the worst case scenario, the fixtures may explode and start a fire.

Lights exposed to moisture or dust, devoid of any form of protection, tend to cloud over because they collect debris, dead bugs, and dirt. These fixtures will also turn brown due to rust and fall apart within a short time.

But, LED vapor tight lights always have clean lenses no matter the wet or dusty conditions. They look well-maintained and hygienic and give a commercial space a professional image. And because these waterproof lights are well constructed, they also last longer and need little maintenance.

Vapor proof lighting fixtures have a rust-resistant die-cast casing. It's einforced poly-carbonate lenses to withstand high abuse in harsh environments and temperatures.

Besides their sturdy build, LED vapor proof lights offer the best performance of all lights. They are very efficient in damp rooms and humid areas. They provide bright, high-quality light without as much as a flicker. They also enhance security measures in a wet location providing light that works with surveillance.


They Make Working Environments Safer for Employees

Waterproof lighting also ensures that employees work under quality light without eye strain. Vapor proof lighting also prevents falls and trips. According to OSHA that can cost up to $40,000 in injury costs per employee.

High-quality, LED vapor proof lights are also vital for production output. Poor lit or over bright environments tend to slow down production. Good lighting creates a great work area that encourages employees to give their best.


They Have the Right Certifications


LED vapor tight lights have certifications for special applications like food preparation facilities. NSF and NEMA list the regulations that guide purchase and installation of lighting in different areas. When you buy lights with these certifications, you can be sure it's high-quality light.

The Disadvantages of Traditional Vapor Proof Lighting

  1. High Maintenance Costs

Fluorescents and HID lamps have short lifespans especially in wet, dusty, or moist areas. Their electrical components degenerate faster when they are switched off and on.

They also perform poor in cold and wet areas, the areas to use vapor tight lighting fixtures. Each time fluorescents are turned on, their cathodes degrade. With a lifetime of 7,000-15,000 hours, the cost of maintenance for these lights can be enormous.


  1. High Energy Costs

As we mentioned, HIDs and fluorescents have a predetermined lifespan that deteriorates fast. Traditional lights also have long warm-up and restrike times. This gets in the way of their ability to work with lighting controls. Because they are on even when they need to be off (to prevent the long restrike time), they tend to use more energy than necessary.

Most vapor tight light fixtures hold about 1 to 4 lamps each for enough light distribution. Traditional light bulbs are inefficient because they produce a lot of infrared energy. Which is lost to the surroundings and wasted. In cold rooms and refrigeration facilities, this heat compounds the energy problem. The cooling systems have to work harder.


Poor Lighting Performance

Some traditional lighting solutions score bad on the color rendering index. For instance, HPS lamps have a low CRI of 22. Wet, damp, or dusty conditions will hurt conventional light quality. This results in poor lit environments. This may also lead to an increase in workplace accidents.

Benefits of LED Vapor Lights over Traditional Lights

LEDs have many benefits over HIDs and fluorescents. Chief amongst them being their excellent ability to enhance energy efficiency. Their many advantages stem from their operational efficiency. They have no ballasts and need little electricity to produce light. They also produce negligible infrared energy and are hardy, so they do not break on impact.

The many upsides of LED waterproof lights make them better in dusty, humid, and wet areas. Let’s talk about 3 of their best benefits.

Lower Energy Costs


A LED vapor tight light will use 40-75% less energy than traditional bulbs. This results in huge energy savings, especially in large facilities. LEDs also won't flood a refrigeration facility with infrared heat, increasing refrigeration costs. They put out little heat and are ideal for facilities with low operational temperatures.

Reduced Maintenance Costs


A LED's lifespan is not affected by increased switching frequency. It can be lit, dimmed, or turned off on demand. These lights also have a long lifespan and work well in freezing areas. This means that a facility with LED vapor tight light fixtures will have small maintenance costs.

Stellar Lighting Performance


Thanks to their multi-point design, LEDs distribute even light and cut light waste by directing light that need it the most. They have an even foot candle distribution because of their 360-degree light distribution.
