Vapor Tight Light fixtures are sealed and gasketed luminaires that provide general illumination for indoor and outdoor environments where exposure to water, humidity, and dust is likely to occur. Commonly referred to as “Wet Location” fixtures as well, vapor light lighting comes in a variety of sizes and shapes, however they are most commonly found in 2ft to 8ft lengths, with conventional fixtures containing 1 to 3 fluorescent lamps per fixture. These luminaires are usually mounted on ceilings, soffits, walls, or in any other commercial and industrial building or facility where exposure to water or dust is a concern.
There are several definitions of what constitutes a “Vapor tight” fixture, consisting mostly of certifications by independent industry organizations. These organizations, such as NEMA, NSF, provide various levels of certification that enable the buyer to determine if a specific fixture is appropriate for their building or facility, such as “Ingress Protection Rating”. For example, a Food Processing plant has very stringent requirements in regards to the conditions that a light fixtures must withstand, compared to a shopping center looking for canopy lighting solutions where indirectly exposure to rain and moderately cold temperatures is the only concern.
Most existing vapor tight fixtures utilize Fluorescent lamps such as T12, T8, or T5. Take a look at our Fluorescent Lighting Application page to learn more about Fluorescent lighting
LED Vapor Tight Lights, also described as Enclosed and Gasketed Fixtures, and Wet Location Fixtures, provide a range of benefits over conventional fluorescent Vapor Tight lighting. As we discussed previously, the way LED’s operate provides inherent advantages over fixtures that utilize fluorescent lamps. The quality of LED Wet Location fixtures has increased dramatically over the past few years and as a result, LED Wet Location Fixtures are adaptable to a wide range of wet, humid and dusty lighting applications. This adaptability is a key benefit of Enclosed and Gasketed LED Fixtures. Often the biggest question when it comes to LED Vapor Tight Lighting is whether to utilize a LED tube within an existing fixture, or to install a new LED Vapor Tight fixture. Ultimately that decision is driven by the customer, and their expectations and constraints as they pertain to budget and desired performance.Energy Savings
The wattage of a 4ft LED Vapor Tight Light Fixture typically ranges from 12 watts to 55 watts, resulting in a 40%-60% percent reduction in energy consumption. The LED Fixture wattage range is so dramatic due to the need to adapt to the many different applications of vapor tight lighting. Since t is common for fluorescent wet location fixtures to utilize between 1 to 4 lamps per fixture, by using LED Vapor Tight Lights in these applications, it is possible to save over $5,000 per year for a building or facility with (100) fluorescent vapor tight fixtures.
Maintenance Cost Reduction
As mentioned previously, the way LEDs generate light and progress through their functional life results in a much longer operating life compared to conventional fluorescent light fixtures. Another advantage realized from LED Vapor Tight Lights is that they are not negatively affected by cycling (turning on and off), so they are more reliable in scenarios where lighting may be turned on and off frequently. Additionally, Light Emitting Diodes function extremely well in cold environments, and would not be subject to the negative effects on product lifetime experienced by fluorescent lamps in similar applications.
Moving on to the way LED Fixtures “DISTRIBUTE” light. As a result of the Multi-Point design, LED Vapor Tight Fixtures often provide a very EVENLY distributed light pattern. The result, in regards to LED vs Fluorescent, is a more even foot candle distribution from the LED conversion. In addition to the even distribution of light, LEDs are available in a range of color temperatures (Correlated Color Temperatures) and as a result provide a range of options to increase the visual perception of “brightness”. This aspect is crucial in manufacturer or food processing facilities where employees need high performance task lighting, and for outdoor retail applications where tenants and companies want to ensure that their products and branding are clearly visible.
