Lights.com—Laser Led Flashlights
The title laser LED flashlights can be somewhat confusing if you try to break down the meanings of LEDs and lasers. In many cases laser flashlights are interchangeable with LED flashlights, but technically they are not exactly the same thing. LED means light emitting diodes, and they produce light while electricity flows through them. LD means laser diodes, and they are semiconductors which convert electrical currents into light. The reason the LEDs and LDs are often interchangeable when naming flashlights is because for the most part, laser diodes act as LEDs.
Laser LED flashlights have the ability to produce very concentrated and focused beams of light. The emitted light from LEDs and lasers is more direct than the broader coverage area of light produced by some of the standard light bulbs. The result of the direct concentration of light is a brighter, but more limited coverage area. This allows for more precision when you are attempting to light a very specific area.
LEDs can produce light in several colors, actually any color of the rainbow. The white light produced by LED flashlights is actually achieved with a blue light that has been coated with phosphorescent materials. Laser lights in emergency flashers and other flashlights with pulse options often have red or orange LED lights. The way the light is dispersed depends on the design of wavelengths flowing through the flashlights.
Benefits of LED Laser Flashlights
The intensity of LED and laser flashlights allow for piercing streams of light which can cut through elements such as fog, smoke, water, rain, dust and others. For this reason, these types of flashlights can be ideal in emergency situations, disasters, or bad weather. Emergency and rescue personnel, as well as law enforcement and the military often use LED flashlights.
