What is Hermetically Sealed in Industrial Lighting

Industrial work sites are filled with dangerous elements that could damage costly, unprotected equipment. The presence of corrosive cleaning agents is a great example, forcing luminaries to fail prematurely or tools to malfunction. Furthermore, in hazardous locations, volatile gases could penetrate electrical components of industrial lighting systems and cause unwanted ignitions.

To prevent such issues, lighting manufacturers seal luminaries in a hermetically, airtight manner. Read on to understand how hermetically sealed units improve illumination in industrial facilities.

Improving Safety

Hermetically sealed lights prevent hazardous elements, which could be gases, liquids or dust, from entering the units. In most cases, this type of enclosure is used to loosely describe specifications or testing grades.

The NEC refers to this term as a technique for protecting the internal components of lighting systems. According to NEC Sec. 500.7(J), hermetic sealing is achieved via welding, fusion or soldering. Additionally, hermetically sealed is not limited to luminaries. It can be used to describe a plethora of explosion proof machines designed for hazardous locations, including HVAC systems and small switches.

Hermetic seals can consist of epoxy resins to maximize effectiveness. The substance is capable of tightly bonding two similar elements, reducing gas leaks with temperature thresholds between -70 degrees Celsius and 150 degrees Celsius. It is also possible to hermetically seal glass and metal together, which is typically used for industrial lights in non-hazardous environments.

What About Factory Sealed?

Contrary to popular belief, hermetically sealed industrial lighting is not the same as factory sealed lighting. Although the two techniques share similar goals, the latter method does not use the same sealing practices, as the contacts in the explosion proof enclosure of a factory sealed unit are molded inside. Factory sealing is considered to be cost effective and common in Class I, Division 2 industrial facilities.

It’s important to highlight that factory sealed equipment are typically suitable for Groups C and D hazardous locations – not Group B (hydrogen, with an ignition temperature of 968 degrees Fahrenheit).  For more information please visit http://www.larsonelectronics.com/

Solar vs Fuel Light Towers: Which One is Better for Construction Sites?

These days, businesses have numerous options at their disposal when comes to lighting systems for construction sites. One of the most popular options today includes light towers. These units can reach heights between eight to 85 feet for elevated illumination.

For remote construction sites without supporting connections to the grid, portable light masts are essential. The temporary lighting systems leverage an external power source, such as a battery-powered solar generator or a conventional, fuel-type generator. Both options offer power to the luminaries, but in the end, only one is truly suitable for your business.

Fuel-powered Light Towers

Light towers equipped with fuel generators are quickly becoming a staple in construction sites worldwide. The light masts are plugged directly into a generator located at the base of the mast. Some generators come with additional plugs and sockets to power equipment around the work site. Fuel-type generators don’t consume a lot of fuel, making them ideal for temporary lighting requirements. They can also be used for long-term projects; however, more fuel reserves are needed to keep the system going. This can be an issue for construction projects that are extremely remote, such as bridges and other infrastructure-type projects.

Another issue with relying on a fuel generator to power your lights on the construction site is noise. The units are loud and distracting, which can be difficult to work around. This forces operators to deploy the units in low activity areas of the location, such as perimeters or sections of the site that are unsuitable for work. From a maintenance perspective, fuel-type generators come with a lot of loose parts that are constantly moving. As a result, the units must be properly maintained to ensure reliability.

Solar (Battery-powered) Light Towers

Solar light masts utilize large panels, controllers and batteries to power luminaries and other equipment on the construction site. Like fuel-type generators, these units may also come with additional plugs and sockets for powering tools.

But unlike the above, solar light towers operate quietly – due to lack of moving parts. Solar components are solid state, which contributes to seamless operation. Because of this, operators can deploy the masts anywhere on the construction site without needing to take noise levels into consideration. Moreover, maintenance is greatly reduced, as the parts aren’t prone to wear and tear.

Some drawbacks of solar light towers include limitations of battery capacity and performance, as well as its reliance on sunlight. Without prolonged exposure to UV rays, the sustainable lighting system won’t be able function properly.

Temporary LED Lights For Construction & Large-Scale Projects

Construction sites are some of the largest consumers of temporary LED lights. The sector relies on powerful luminaries during after-hour operations. During this period, urban activities are at their lowest, allowing workers to bring in machines and obstructive equipment, such as cranes and dump trucks, to the site with minimal interference.

Portable and Heavy-duty

Busy construction sites have very strict requirements surrounding the type of lighting products and systems for such projects. Most operators require temporary LED lights to have a high degree of portability. For example, at the early stage of construction, buildings are lacking walls and ceilings. Because of this, standard high bay lights that are mounted on ceilings or surfaces cannot be used. Instead, portable string lights with C-hooks may be deployed around the location. These units allow workers to mount individual luminaries on scaffolding’s, poles and other nearby structures.

They can also be carried by hand for detailed tasks. Construction string lights are daisy chained (connected) and utilize a single source of power (see more at: Larson Electronics). This reduces the need to setup and tear down individual lamps on the site.

For intense lighting requirements, businesses may deploy luminaries that are mounted on carts or stands. The units are ideal for such applications because workers can easily transport the lights around the site effortlessly. For LED lights on carts, it only takes one person to move the unit from one location to another.

LED Light Towers for Construction

Elevated LED lighting systems are extremely common in construction sites. This includes LED light towers that are capable of reaching heights between 8-70 feet, depending on the needs or scale of the project. Like temporary construction LED lights, these units are designed to mimic permanent luminaries that are mounted on poles.

LED light towers for construction are recommended for tasks that need bright illumination for long periods of time, such as welding, setting up foundations and etc. The luminaries may also be used to highlight checkpoints and high activity areas.

To withstand the rough environment, LED light towers are typically waterproof, weatherproof and capable of standing up to strong winds. Moreover, the light masts may also be supported by a generator, for remote construction sites that lack access to mainstream power sources, such as the city grid. A new trend in LED light towers is the use of solar energy, in place of fuel-powered generators. These cutting-edge units offer quiet operation and clean energy during operation. They can also be paired with a day/night photocell to reduce energy consumption during the day.
