Flashlights are a necessity in any home or toolkit, and good quality flashlights are compulsory for many occupations. The price of white LED flashlights has gone down considerably since they were first introduced, allowing more consumers to go green with their flashlight purchase. The wide availability and variety of white LED flashlights lets even those who are the most demanding find the right light for them. This article will examine the benefit of using these flashlights and the types that are available.
White LED Lights
Light emitting diodes, or LED´s are small semiconductors that have been doped with extra electrons to produce light. This means that there is no filament burning as in incandescent bulbs, preventing them from getting hot. Light emitted by the diodes bounces off the inside of rigid plastic bulbs toward a curved tip, concentrating the light. White LED bulbs are actually ultraviolet or blue light emitting semiconductors which are converted with a yellow phosphor coating on the bulb.
Energy Efficiency
Whether in regards to the use of batteries or the bulbs, white LED flashlights are more efficient. As LED´s mostly use electricity for light and not heat, battery life in an LED flashlight is tens hours longer, depending on the power and brightness of the LED´s in the flashlight. In regards to lifespan, some LED bulbs can last up to 100,000 hours which is a monumental difference when compared to incandescent bulbs. Most people replace the flashlight before the bulb ever needs to be replaced in an LED flashlight, most probably because they have either lost it or would like a change after so long!
Other Benefits
The portability, durability, and focused beam of white LED flashlights are benefits that cannot be ignored. Since less batter power is required, many white LED flashlights can run on fewer or smaller batteries, making the flashlight much smaller than an old style one. In addition, without a filament inside or a glass casing to break, LED lights are practically indestructible. Unless the flashlight itself breaks, an LED flashlight will not stop working if dropped. Another advantage is the fact that LED´s give off focused light which means that it is possible to directly illuminate an object from a distance which was often difficult with standard flashlights.
Types of LED Flashlights
LED bulbs come in a variety of sizes. Flashlights may contain just one bulb or a group of bulbs together. Just as bulbs come in a variety of sizes, so do flashlights. No matter what the need, white LED flashlights can fill it. Penlights and keychain lights have become smaller and more efficient with the use of LED´s; regular size flashlights for home, shop, or outdoors are more resilient; and for those who need a flashlight at work, white LED flashlights will last for several shifts without needing any maintenance.
White LED´s are the green way to light a path through darkness. With intensely focused light from a durable, energy efficient flashlight, any job will seem easier. Big or small, one bulb or fifty, a white LED flashlight is a must have for people of all ages from all walks of life.
