Industrial Flashlights Use LEDs

Recoil LED flashlights are brighter, use less energy and extend battery life by 50%

For industrial use, flashlights should not only illuminate clearly and brightly, but also be capable of producing a beam that is capable of penetrating the dust, steam, fog, exhaust, or other particulates that can so easily obscure vision around machinery. This, of course, should be accomplished with a minimum number of battery changes, bulb failures, or other inconveniences that can hamper industrial safety or efficiency.

LED Industrial Flashlights for Safety

Fortunately, a brand new light emission method called Recoil Light-Emitting-Diode (LED) Technology is being applied to industrial flashlights that will not only make your job easier but also safer.

Pioneering the new technology in the industrial safety and security industries is Torrance, California-based Pelican™, a manufacturer and innovator of advanced lighting instruments. Derived from the mechanics of lighthouses and locomotive headlights, which demand focused light beams capable of cutting through fog and haze for long distances, Recoil LED Technology enables better flashlight focus, brightness, longevity, and durability for safer, more secure industrial processes.

LED vs Incandescent and Halogen Energy Efficiency

The Journey from Incandescent to LED Lighting Despite the 120 plus years since Edison invented the incandescent bulb, it remains tremendously energy inefficient, with just 4 to 6 percent of the electrical power supplied to the bulb converted to visible light. Moreover, incandescent light bulbs "burn out" quickly.

The halogen light, found in many flashlights, also uses a tungsten filament but enclosed in a much smaller quartz bulb. Halogen bulbs emit more light than standard incandescent bulbs, but they are also extremely energy inefficient, often burning out only 50 hours of use.

Moreover, in flashlights, both halogen and incandescent bulbs cast a washed-out oval-shaped pattern of light, sometimes known as the "fisheye effect." This is due to scattered peripheral light reflecting imperfectly forward off the flashlight reflector.

LED Technology is Sturdy and Compact

As an alternative, newer and cooler light sources such as light-emitting diodes (LEDs) are not only more energy-efficient, but also sturdier and more compact. For energy efficiency and longevity reasons, LED technology has already been applied to create a generation of LED flashlights. But existing LED flashlights cast only a wide, diffused beam capable of illuminating objects only several feet away.

LED Technology to Throw Light

The problem with existing LED technology for spot illumination is that it's primarily "designed to be seen and not to see with." The round tip of tiny LED bulbs provide a fine viewing angle for applications such as display panels, but scatter light too widely to be used effectively for flashlight or spot lighting purposes.

Instead, Pelican's Recoil LED Technology for flashlights takes the opposite, counterintuitive approach. Like a lighthouse, the new technology focuses light by firing it backwards. A special parabola-shaped reflector then captures 100 percent of the light and reflects it forward.

The resulting parallel-focused beam of light is free from scattered peripheral light, which greatly increases its ability to cut through obscure environments like smoke, fog, and dust. Since there is no filament involved in the process, the bright white, color spectrum-tested light is also free of the annoying black spots, shadows, and distortion found in traditional filament-based lighting.

As a result of Recoil LED Technology, the first two flashlights from Pelican that incorporate this technology - the SabreLite(tm) LED and the M8 LED - are considerably brighter, consume less energy, and extend battery life by approximately 50 percent. The flashlights have been demonstrated to generate a beam 33 times brighter than the nearest LED competition, with a lux reading of illuminative intensity of over 1558.

LED Bulb life of 10,000 hours

Recoil LED Technology provides focused light for up to 10,000 hours of bulb life in the new flashlights, instead of once every 50 hours as with traditional incandescent or halogen bulbs. Exclusive voltage regulated LEDs also maintain the flashlights' peak brightness longer, whereas conventional flashlights' brightness level declines steeply from first use. To achieve this, electronics in the new flashlights check battery power and increase current over time so a constant wattage is maintained.

LED Technology Approved for Use in Hazardous Locations

The new flashlights are approved for use in hazardous locations by third-party certifiers such as UL, FM, CE, and MSHA, as well as engineered to continue working after drops of 30-feet. They are sealed to prevent ignition from sparking in hazardous locations, such as near flammable gases, liquids, dusts, or fibers, and are arguably the most safety-approved flashlights on the market today.
