Myths and facts about industrial LED lighting

By Bizled Bureau

September 12, 2015: Due to LEDs unique characteristics, they are becoming popular for industrial applications. Despite its little high cost than conventional light sources, LEDs are more durable, reliable do not need any maintenance. The most advantageous factor it their long lifespan, as long as 50,000 hours. With properly designed fixtures, LEDs can operate well in all temperature environments, and are much more energy efficient than the conventional light sources.

High cost factor of LEDs

However, people seem to have some myths regarding usage of LED lights in industries. We need to make industries aware that LEDs are cost-effective replacements for fluorescents, HIDs and other industrial lighting. While initial purchase costs for LED lights are a little higher than fluorescents, the price difference is just a one-time issue. Moreover, they are energy-efficient, and hence you will save a lot of energy, and hence will be delighted with a lesser electricity bill.

Unlike past decades, when lighting-related energy costs played a relatively small role in purchase decisions, a decade of rapidly escalating energy prices has transformed energy use into the major cost driver for industrial lighting.

Industrial organisations should not trade off for shorter initial payback periods?usually measured in months, they should look for long term benefits, say for years. From a purely financial perspective, it makes sense to go for LED lights in industries.

LEDs don?t require maintenance

This is a myth that LED lights require maintenance. People think that the magnetic ballasts of LEDs require servicing and replacement from time to time. But the fact is that LED lights have electronic drivers, which do not need replacement. Today these drivers are designed to face any type of rugged environment. A magnetic ballast used in traditional industrial lighting like HID, HIF, HPS, metal halide, wear out fast, requiring servicing or replacement. And in large industrial facilities with hundreds of fluorescent or HID lights, servicing magnetic ballasts is quite expensive. But LEDs are semiconductors with electronic drivers, which play important role in managing the power delivery and makes the light energy efficient. Because LEDs use electronic drivers, they provide LED manufacturers with the opportunity to integrate control features like sensing, dimming and instantaneous on/off, into lighting fixtures for maximum functionality and efficiency.

Well-designed LED driver don?t fail

Well-designed LED drivers don?t fail during the usable lifetime of an LED, which generally 50,000 hours. It is unlikely that a driver or any other component would need to be replaced. Furthermore, in a well-designed LED fixture, frequent on/off switching does not shorten its useful life, unlike traditional fluorescent or HID lighting fixtures whose useful lifetimes are significantly reduced by such operations. In fact, frequent switching actually lengthens the useful life of an LED, as turning off an LED fixture slows the pace at which total operating hours accrue.

LEDs don?t contain mercury

People usually think that LEDs contain mercury like fluorescents. But LEDs are mercury free and are not harmful. They work well in high temperature environments. In fact, well-designed LEDs work well in any type of environments. A well-designed lighting system that manages heat dissipation well is a prerequisite for lighting operating at any temperature?hot, cold or anywhere in-between. LEDs also perform extraordinarily well in cold environments.

LEDs can manage glare

A glaring lighting system is not suitable for many industrial facilities. Today, LEDs are designed well to manage glare. All high-output lights are bright. Once the newness wears off, the glare passes quickly. Moreover, well-designed optics on LED fixtures also minimise direct brightness and glare. And, LEDs now have excellent colour temperature for industrial environments.
