One of the most versatile flashlights on the market today is the UV LED flashlight. These flashlights have many practical uses for the ordinary consumer and are a good addition to anyone's collection of tools. They are also more energy efficient and resilient than the UV flashlights previously available. Below is a small insight into the benefits, features and information on why you should use a UV LED flashlight.
What is Special about UV?
Of the spectrum of light given off by the sun, only a portion is visible to humans. UV light is only visible as a deep purple or blue glow that is best seen in the dark. Besides lighting up black light posters, UV lights make many things visible to the naked eye that cannot be seen in visible light. The one area that people must be careful is the risk that UV lights have with eyes. If UV light is shone directly in the eye, blinking to protect the eye will not occur, so eye damage is possible without even realizing it. For those who are extra cautious, special safety classes are available which are inexpensive.
Uses of UV Light
One of the most common known uses for UV light is to see bodily fluids. Television shows often depict forensic investigators using a backlight to show blood. But why should you use a UV LED flashlight? Hunters can use an UV LED flashlight to follow blood trails of animals they have marked. Another great use for them is to ensure the cleanliness of surfaces, especially in the bathroom. Many health conscious people take UV flashlights on vacation with them to inspect surfaces in a hotel room before accepting the accommodation. Another ability of the UV LED flashlight is to detect counterfeit money, which in itself could be worth the purchase.
Benefits of LED
The question of why you should use a UV LED flashlight is easily answered due to their extraordinary efficiency and durability. Eighty percent of the energy used by LED bulbs is converted to light, which is far superior to the 20% conversion rate of incandescent bulbs. This equals to tens of hours of battery life. Imagine going months or even years in some cases without changing a flashlight battery. In addition, the LED bulb is very tough, with a life span in some measuring 11 years of continued use. Impact, vibration, and temperature resistance also make LED the standard of the future.
Things to Look for
There are many features and types of UV LED flashlights available from which to choose after you recognize why you should use a UV LED flashlight. The most important decision will be the power source. Is the flashlight rechargeable or run by crank or disposable batteries? Next, look at the LED bulbs that are in the flashlight. Since LEDs are small, different types of bulbs can be placed in one unit such as UV, laser, white, and colored lights, expanding the available uses of a single unit. Light intensity and beam angle is also very important in any LED flashlight as well as size and water resistance. In some flashlights it is even possible to refocus the beam, or have multiple lighting modes.
Why should you use a UV LED flashlight? The answer is simple. Detection of a myriad of things unseen makes UV light an invaluable tool. The energy efficiency and ruggedness of LED is superior to all other bulbs available today. This combination makes this flashlight a must have.
