LED flash lights are quickly becoming high-demand items in the flash light industry. The energy efficiency and durability of LED bulbs are difficult to compete with. Although they may cost more than conventional flash lights, in the long run you will actually save more money since incandescent bulbs use more energy and have shorter life-spans. Here are a few useful facts about LED flash lights .

History

Before LED bulbs were used in flash lights, there was only incandescent light. But in 1999, Lumileds Corporation of San Jose, CA introduced the Luxeon LED, a high power white-light emitter. Lumileds began manufacturing flash lights using these bulbs, and thus, LED flash lights were born.

LED flash lights are different from conventional flash lights because you are able to control what types of light frequencies are emitted. Color is dependent on what type of material is used and how much energy is required to energize that material. For example, materials that require a low level of energy will produce infrared light, while materials that require a high level will produce blue light.

More energy efficient

The primary advantage of LED bulbs over conventional bulbs is LED’s use less energy. In conventional flash lights, energy courses through the filament wire in the bulb and light is created. However, these types of bulbs tend to heat up over time. The heat that dissipates from the bulb is lost energy, energy that could have been used to produce light.

In LED flash lights , the bulbs contain two types of semiconductors - one that has an abundance of free electrons and the other has a deficit. When energy is applied it causes the electrons to jump from one semiconductor to the other, creating a photon of light. This method of producing light does not create as much heat as the conventional method, and thus less energy is transformed into heat and wasted.

LED flash lights are significantly more efficient that conventional flash lights, particularly at low light levels. LED bulbs typically use 5% to 10% of the power used by conventional light bulbs, which translates into a significant reduction in cost.

Longer life

LED bulbs are not only more energy-efficient than regular bulbs, but they also last longer. First of all, LED bulbs are coated with a clear solid resin, which makes them extremely durable. To illustrate, if you drop an LED flash light on a hard surface there is very little chance that the bulb will be damaged. Bulbs can have extremely long lifetimes, as long as hundreds of hours, as opposed to conventional bulbs wherein filaments eventually burn out. Usually, LED flash lights are also usually waterproof.

Higher quality light

In conventional flash lights, reflectors are required to focus the light. This is because in conventional bulbs, light is emitted in all directions. However, in LED flash lights reflectors are already installed in the bulbs themselves, and are capable of producing focused light. With LED bulbs you are also able to generate a particular color or range of light without the use of filters. Finally, LED flash lights maintain a constant light intensity, even if the batteries begin to die. In regular bulbs, however, light grows dimmer as the batteries lose power, up to 50% in some cases.

It is because of these strong advantages over conventional flash lights that more people are turning to LED flash lights . LED bulbs will not eat up your batteries as quickly as regular bulbs, will last longer, and will produce higher quality light. In the long run, the durability and quality of LED flash lights will pay for itself.
