Knowing Different Kinds Of Lamps Used In Industrial Lighting

Mar 02

There are different types of industrial lighting and each type has its own advantages and disadvantages. Finding a lighting arrangement that is most cost efficient and effective can sometimes be challenging.
 
 
Lighting is essential to our daily activities. It is particularly important in the work environment, as it allows for efficacy and safety. Electric lighting is needed in the areas where natural light cannot reach. There are three categories into which industrial lighting can be broken down: general, emergency and supplemental lighting. General lighting is the illumination pattern that is usually implemented inside the facility. Supplemental lighting is extra lighting with more intense focus on a specific area, such as a workstation. Emergency lighting is lighting powered by a battery or a generator, which is used when power is lost or interrupted. Although different, these three types of industrial lighting methods use the same basic principles.
 
 

Here is an illustration on different types of lamps used in industrial lighting:
 

Incandescent

Incandescent lamps are the most common type of lighting. An electric current is passed through a thin wire filament to create heat that produces white light. These bulbs may be used with any type of lighting device, including supplemental, general or even decorative. Incandescent bulbs produce light and create a welcoming atmosphere. They can last for about 500-1000 hours. They are efficient (up to 18 lumens per watt) and are easy to install.

 

High Intensity Discharge

High intensity discharge (HID) lamp passes an electric current through an inner tube filled with a pressurized gas mixture to create the light. HID lighting is available in three types, including metal halide, mercury and high pressure sodium. This source of powerful light is commonly implemented in landscape lighting, general lighting and outdoor artificial lighting. HID lamps gradually reach full brightness as it takes a few minutes to warm up.
Fluorescent

 
The fluorescent light is created when an electric arc is passed through an inert gas. The arc produces heat which vaporizes droplets of mercury and emits ultraviolet (UV) light. There is a phosphor coating inside the bulb that glows when it interacts with UV light. Fluorescent lamps can be highly efficient, with a maximum output of 105 lumens per watt. These lamps use less than one fifth of the energy that incandescent lamps use and can last up to 20 times more. Fluorescent lamps usually last for about 12,000 to 24,000 hours or more.

 

Compact Fluorescent

These lamps are similar in function to standard fluorescent lamps. They can easily be used in regular sockets and serve as an energy-efficient replacement for incandescent lamps. They have an energy efficiency of 105 lumens per watt and can last for up to 9000 to 10000 hours. For best results, they must be used in places that are in use for several hours at a time.

 

Halogen

These lamps create light through a small wire filament which is covered by a quartz tube containing pressurized gaseous halogen bromine or iodine. They create a whiter and brighter light as compared to incandescent bulbs as it burns hotter. These bulbs are commonly used in headlights, flood lights, display or accent lighting. They are available in different styles, such as reflective spots and floods, parabolic aluminized spots, double or single ended quartz and mini-can bulbs. These lamps can produce a more intense light that can be concentrated on a specific area. They have the energy efficiency of about 22 lumens per watt and usually last for about 3000-5000 hours.
 

Why buying costly but energy efficient lights can save you money?

The lighting system cost not only depends on the cost of the lamp itself but also on the installation and use of electrical energy. Electricity is actually responsible for 80-88% of the total cost. The labor cost of installation is approximately 8%, whereas the cost of the lamp is approximately 4% of the total. This is the reason why using energy efficient lights with the longest life actually reduces the costs. For example, buying compact fluorescent lamps has a higher initial investment; however, the money you save through reduced electricity costs significantly reduces the overall cost.
