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.

What IP Rating Should You Choose For Your LED Fixture?

 

A popular LED water tight fixture is a  vapor proof light. They have 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:
  • food processing facilities, stairwells, subways
  • laundry facilities, swimming pools, car washes
  • 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.

E

IP65

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.

E

IP67

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.

E

IP66

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

E

IP68

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.
