Heavy Duty Emergency Lights

Types of Heavy-Duty Emergency Lights and Applications

“Heavy-duty” is one of those variable terms that can change in definition, depending on its application. In the case of emergency lights, the term heavy-duty refers to lights that are used in applications where damage to the lamp assembly, specifically the lamp case is possible. In other words:

  • Normal-duty lights (anything that doesn’t say “heavy-duty”) can be used in offices, conference rooms, entryways, and corridors.
  • Heavy-duty lights should be used in all manufacturing, warehouse, industrial and exterior applications.
 Steel Emergency Light

Steel emergency light fixtures provide sturdy construction and reliable exit pathway illumination.

Although this is not a regulatory requirement, the risk is in having a light damaged by worker, forklift, or the weather, rendering it inoperable. Should that happen, your facility would not be up to code, and could result in a fine if you are inspected. Even worse, a worker could be trapped inside the facility in a true emergency situation.

Heavy-Duty Emergency Light Types

Even within emergency lighting, the term heavy-duty lights can be divided into a number of categories:

  • Steel emergency lights – Most heavy-duty emergency lights are made of steel construction. This term applies to the light case construction. While thermoplastic housings tend to be more attractive, they are also more susceptible to damage. Steel emergency lights are constructed of 20 gauge steel sheet, protecting the inner workings of the light from damage.

  • Wet Location emergency lights – Wet applications for emergency lights are those that are directly exposed to the weather, specifically exposed to rain. This can include any lighting that is attached to the exterior of the building, except in those cases where the lighting receives partial protection from the rain. Pole mounted lights are also included in this category. Wet application lights are sealed to prevent the entry of water or moisture into the lamp housing, and to prevent splashing of water into the bulb socket.

  • Industrial emergency lights – Industrial emergency lights offer a higher level of protection from the elements than wet location models. The fiberglass housing of industrial emergency lights is NEMA 4X rated which means it is water and corrosion resistant. NEMA 4X rated emergency lights can be installed into wash down areas where hoses are used to spray water as well as areas that feature windblown dust particles. They are also ideal for outdoor application including freezing temperature environments.

  • Hazardous location emergency lights – When flammable, volatile compounds are in use, such as solvents, paints, and petroleum products, regulations call for the installation of explosion-proof emergency lighting. These lights are fully sealed to prevent the entry of any vapors to either the internal electronics or the bulb connection. Hazardous location emergency are rated for different types of environments. Class 1 Division 1 and Class 1 Division 2 hazardous location emergency lights are the most popular tyles.

Choosing Heavy-Duty Emergency Lights

Industrial Emergency Light

Industrial emergency lights are NEMA 4X rated for tough environments that feature wind, water, dust, and even freezing temperatures.

Heavy-duty emergency lighting is more expensive than standard emergency lighting, it pays off in longer life and reduced risk of non-compliance fines. To minimize the overall cost of your emergency lighting system, you must understand the exact application in each area where you need to install emergency lights.

Emergency Lights that are Heavy Duty

Some companies install the same emergency light throughout their facility, seeking the worst-case scenario, and buying lights to meet that need. While this is commendable from a safety standpoint, it is not an effective use of your company’s resources. Paying the extra cost to install wet duty lights inside your building, in order to maintain consistency, will only pay off if the roof of your building is blown off.

Likewise, buying higher wattage units for all applications, just because you need them for some applications, is spending money that you can utilize elsewhere. You can maintain some consistency by buying all of your lights from the same series, without having to buy more lighting than you need. To be the most effective, you must analyze each individual application and choose the most effective light for that particular location.
