Flashlight buying guide

Gone are the days when buying a flashlight meant one would automatically looking Maglite. While acknowledging the impact and the unprecedented success of Maglite design, LED, HID (High Intensity Discharge) and Xenon technology along with ultra strong coating materials means that the Lantern has evolved into a State where the stronger beam is not necessarily means the larger the flashlight.

When looking for a high performance, affordable lighting tools is easy to become swamped by the amount of brands in the market. Flashlight technology at the beginning of the 21st century offers a bewildering variation of the type of lamp, material of the body, body size, source range and price of energy. This guide is an overview of the salient points worth consideration when buying any quality flashlight.

In the same way that the legs measure length so measured brightness. lumens The higher the count of lumen, brighter and more the beam will show. Occasionally you can find the brightness levels measured in candelas or intensity, this describes a unit Candlepower light at source. Candelas/Candela intensity equals 12.57 Lumens.

Perhaps the most significant breakthrough in lighting technology was L.E.D (Light Emitting Diode). The L.E.D. produces light at the molecular level as distinct from a normal lamp that heats a filament, so using more energy to produce less light. As a result a L.E.D. will last a lifetime and dramatically increase the life of a battery. They do, however, vary in degree of purity. Like diamonds, at the point of production some produce clean white light while others have a very light shade of blue, green or violet.

Xenon lights produce a wide spectrum of light (including infrared) and can be made to have a high maximum lumen output by adding Xenon gas in the bulb light to be produced at a higher pressure, thus, but they are comparatively less efficient users of power. H.I.D technology (High Intensity Discharge) Xenon lamp uses a slightly different with the addition of an outer bulb and an inner tube with a partition of cerium doped quartz bulb in to block most ultraviolet rays. HID lamps have Lumen output of approximately 500-1000. Lighting technology can be described as a battle between the light and heat as energy to produce heat affect, which produces light. The undisputed master is the LED. Does light without the need to heat a filament, thereby increasing battery and bulb life. However the power of a Xenon lamp can be amazingly brilliant even harder the batteries.

Enclosure material progressed so far to be nearly indestructible if dropped and virtually water-resistant in very wet conditions. A good, quality Lantern will invariably aerospace aluminum body and a robust construction and design.

Manufacturers vary in quality and specialty. Surefire has a quality range of Xenon and LEDs with a wide range of accessories. Ledwave produce LED lights and Xenon excellent, powerful and reasonably priced. Nextorch can boast the extraordinary Saint, able to produce an enormous 450 lumens, plus a range of ergonomically designed, versatile LED, Xenon and rechargeable flashlights.

Navigate the maze of Lantern production is complicated and, ultimately, dependent on that work will request it. Lumen output to size ratio, durable material resistant coating/bulb and battery life are essential elements to be taken into consideration when choosing a lighting tool for last and perform over time.
