What is an LEP Flashlight?
LEP (Laser Excited Phosphor) is lighting technology that produces strong, efficient light with an emphasis on beam distance. LEP Tech is already popular in applications such as automotive and projection display devices due to the clear, powerful beam it provides. With that in mind it’s a natural leap to use LEP for flashlights, and we’re confident that they will be along the new cutting edge in the coming years.
How Does an LEP Flashlight Work?
The process of creating Laser Excited Phosphor light involves emitting a blue laser through a focused lens. This laser hits a phosphor element backed by a metal substrate, which is then reflected converting the beam to a broad-spectrum light. The resulting beam is the telltale bright white and long reaching LEP light!
Making A “White Laser”
By definition a white laser is a misnomer, a laser being monochromatic and the color white being an amalgam. To achieve a similar effect blue-emitting LEDs, Indium Gallium Nitride (InGaN), along with yellow phosphor powder (most commonly Yttrium Aluminum Garnet (YAG) are used. This Phosphor-Converted LED utilized the blue light to excite phosphor powder, resulting in combined yellow and blue wavelengths to produce a broad spectrum white light.
A Note on Efficiency
One thing that sets LEP lights apart is the incredibly high efficiency of their emission, requiring less power for more light than other sources. This is due to the utilization of blue light. The typical drive current required to produce desired light intensities in blue lights is 4.2 mA, as opposed to 8.8 and 10.5 mA in red and green lights respectively.
Are LEP Flashlights Dangerous?
No, LEP flashlight do not present any unique dangers as a result of their light generation mechanism. These flashlights are no more dangerous than any standard LED flashlight. Just as with any strong light source, pointing it directly into anyone’s eyes is not recommended and could result in retinal damage.
LEP Vs. LED Flashlights
So the big question remains – are LEP set to replace LED flashlights? The answer is quite simple – it depends on the application. While LEP lights boast incredible efficiency and beam distance, standard LED lights will typically have a wider spread beam for area lighting. With this taken into account LEP lights are ideal for specific tasks such as long distance spotting while LED lights are better all-rounders.
What are LEP flashlights used for?
LEP (Laser Excited Phosphor) flashlights are used for a variety of purposes, thanks to their unique and advanced technology. Here are some common use cases:
-
Outdoor activities: LEP flashlights are popular among hikers, campers, and hunters as they provide bright and focused light that can travel long distances.
-
Tactical/ Law enforcement: LEP flashlights are also popular among law enforcement agencies as they provide a highly focused beam of light that can be used for search and rescue operations, tracking, and tactical situations.
-
Everyday carry: LEP flashlights are compact and lightweight, making them an excellent everyday carry item to keep in your pocket or bag. They can be used for everyday tasks such as lighting up dark rooms, searching for lost items, or fixing something in a tight space.
-
Emergency situations: LEP flashlights are reliable and durable, making them ideal for emergency situations such as power outages, natural disasters, and roadside breakdowns.
Overall, LEP flashlights are versatile tools that can be used for various purposes. Their advanced technology provides bright and focused light that makes them stand out from traditional flashlights.
