Ultraviolet or UV flashlights are used by many professionals such as police and air conditioning technicians. They also have several domestic uses and are a good addition to your home toolkit or travel bag. The UV LED flashlights available today have gone to the next level; they are practical and even more durable than the previous editions.
What is UV?
Light has many different wavelengths, some of which are not visible to humans. Ultraviolet or UV light is one type of light that is not in the visible spectrum. When UV light is viewed, it is seen as a purplish light that is very hard to see in daylight. UV light is commonly known as black light for this reason.
Why Use an UV Flashlight?
Over the years many applications for UV light has been discovered. Professionals in many fields have turned to UV lights to help solve problems. However, the everyday person can benefit from UV LED flashlights too. UV light revives glow in the dark items such as watch faces and posters. UV light reflects off bodily fluids, so it can be used to ensure the cleanliness of the home or to track animal trails by hunters. This is also a practical tool for hotel guests as well as staff. Counterfeit bills can be easily detected with a UV light. UV also allows visibility of traces of drugs, which can be useful if there is a wild teenager in the house.
Benefits of UV LED Flashlights
Traditional UV flashlights use much more power than the LED´s options with the old bulbs become useless much faster. Compared to a maximum of tens of hours of use without maintenance for a traditional flashlight, LED flashlights can go hundreds or even thousands of hours without a battery or bulb change respectively. These two factors make UV LED flashlights much more energy efficient. LED bulbs are also more durable as there is no breakable filament and they are made of plastic instead of glass. They also have great resistance to vibration and temperature. One other benefit to an LED flashlight is that both visible light and UV LED´S can easily be placed in the same flashlight, eliminating the need for two flashlights.
Safety of UV LED Flashlights
There is only one danger associated with UV LED flashlights. These lights should never be allowed to shine directly into a person's eyes since they can easily cause damage. Since UV light is not seen, the need to blink from too much light is absent. Secondly, LED´s give off highly concentrated light, unlike incandescent bulbs that spread light over a large area. Due to this, most of the light given off by an LED bulb is directed where it is aimed.
If purchasing a new flashlight, why not buy an UV LED flashlight? Along with the green benefits of having an LED flashlight, the added benefits of UV capability make these lights so much more entertaining and practical.
