The single greatest advantage with LED technology over traditional light fixtures is simply its durability. LED’s solid state technology make them naturally highly resistant to impact and vibration; and with a well designed LED fixture it should provide several years of service without the expense and waste of having to replace the bulb/ ballast or unit. But the most important reason for using LED technology in a Heavy Industry environment is for Safety.
A PTLX fixture will provide more usable, enduring illumination than any traditional HID, Halogen and most LED fixtures , and and is more powerful watt for watt than any other LED fixture in its class. When it comes to what matters for our customers, avoiding a preventable accident is paramount to any costly inconvenience.
According to MSHA, the majority of accidents related to lighting are from falling off equipment or the breakage of lens or bulbs, and has contributed to hundreds of related claims.
By reducing the frequency of these fixture changes and fixes so are the chances of preventable accidents.
It goes without saying that if you’ve had the misfortune of accidentally touching a Metal Halide (HID) or HPS fixture you’ve experienced the burn from the excessive temperatures they can produce. In fact, it’s almost standard to see a grille of some sort in front of the lens to try and prevent this type of accident from occurring. Incidentally, heat from an LED fixture is also very problematic.
Many of our customers comment they see LED fixtures that produce a significant amount of heat through the chassis. This should be a red-flag of sorts and is typically indicative of a design related issue.
When investigating the options of Heavy-Duty LED technology, have the rep turn on the light and have them leave it on for a good 30-40 minutes, then with care, test to determine how hot the chassis becomes. If you can’t pick up the fixture start asking a lot of questions. (Where are the fixtures manufactured? Who manufactures the diodes? Do they have IES files or an LM79 report for their fixtures? How hard are they driving the fixture?) Heat will systematically and prematurely reduce the longevity of the fixture, and you’ll be paying for something that won’t likely last as long as they are purporting.
There is a couple of things to consider with respect to LED technology and the visibility it ‘creates’ over traditional lighting fixtures.
First, LED’s are typically designed so that the light emitted is hemispherical or directional in nature; in contrast to bulbs and reflectors (HID, HPS) that emit light spherically and where much of the lumens from the light is lost in its output. Some folks speak to the ‘shadowing affect’ that many traditional light fixtures, and even some inferior LED fixtures, cast in lower light or dark environments.
PTLX's Heavy Duty LED fixtures will eliminate this shadowing issue because of the strength and design behind the light that is produced, creating a safer environment for the night operator who will see more clearly with less ocular fatigue.
Secondly, as human’s our eyes respond differently to differing levels of ambient light. During the day the cones of our eyes are primary in our visibility function and will modulate to accommodate for differing light levels. However, in environments with little to no light, the rods of our eyes become primary in our ability to see, called scotopic vision.
Scotopic vision sees a different color of the light spectrum . . . . in the blue range rather than the yellow/green range of the photopic vision used by our cones during the day. That said, light color has an impact on what we see and how well we see them . . . . . . two very critical things when operating heavy machinery. Although LED lighting designs can be developed throughout the color range spectrum, most heavy duty LED lighting applications are using a 5000- 5700 (CCT) with a Color Rendering Index (CRI) of greater than 70, which will offer significantly better visibility, for most applications*, for heavy duty operators.
*It is important to note that many applications where glare can contribute to safety, interferring with night vision, that a lower kelvin (CCT) fixture is preferred. We specialize in 2700K color fixture options and its related applications!
Don’t let too little, or the wrong kind of light be the reason behind the next preventable accident.
