UV Flashlight Protection Function Description

1.Low Battery Indicator : battery voltage between 2.9V and 3.1V, UV flashlight appears to be faintly bright with flashes of two flashes per second.

2.Battery Reverse Protection : the UV flashlight is not bright when the battery is reversed, and there will be no abnormality, no worry about burning the battery or the circuit.

Note: The UV Flashlight has black and gray (random delivery), both has optical filter, in which most of customers are used for detection and identification. Purple light of bring optical filter is more pure. If you don’t need optical filter, please explain in advance.

Other Knowledge about UV Flashlight

UV Light, as a black light, plays a significant role in our life. Because of small, portable and versatile, more and more people are paying attention to UV Flashlight. Now, we share share with you some of the power of the purple flashlight in daily life.

1.Fishing Light

Many anglers like to fish at night, and when they float with fluorescent, they will need a UV Flashlight. According to the fluorescence reaction, the effect of violet light is the best, but no matter how many wavelengths of ultraviolet light is harmful to the human body. What's more, long periods of staring at the surface of the water, ripples on the surface of the water indirectly reflect UV light causing discomfort and fatigue in the eyes. Purple light, because of manufacturer different craft effect, can have very big difference, so customers choose professional fluorescent lamp is very important. In addition, try to keep the rays parallel to the water surface, so that the eyes of the fish and people are small.

2.Security Observation

COINS, drivers' licenses, passports, bank CARDS and even stamps have anti-counterfeit labels. Because of having fluorescent ink, purple light is the best detection tool. UV Flashlight can be seen everywhere in daily life. In the market, different wavelength of UV Flashlight has different price. In terms of the use effect, the shorter the wavelength, the more obvious the effect, the greater the number of watts, the better the effect, not just the brightness and the number of lights. But for daily use, 395nm will be tested, and 365nm will be better.

3.Air Conditioning Leak Inspection

It’s closely related to air conditioning maintenance personnel. With increasingly advanced detection methods, then trouble is no longer to bubble water detection, only need a tiny fluorescent agent spray, air conditioning and a half hours, with a high power high strength purple light flashlight illuminating, where there is a crack and is be clear at a glance, convenient and quick.

4.Pipeline Leak Detection

Car line pipes, water pipes, pipes and other pipe leakage, purple light flashlight is also a necessary device, the principle is consistent with air conditioning leak detection.

5.Geocaching

Now the domestic and foreign players like to linger on the national geographic treasure, only a small GPS combined with various wavelength UV flashlight that you can open a period of adventure. Little violet light flashlight also is really powerful and essential.

6.Detect Various Fluorescence Reactions

Diapers, sanitary napkins, tissues, clothes, laundry detergent, cosmetics, urine, GHB, LSD, etc.. The only thing you can't think of is fluorescence without UV detection. Now people pay attention to health, there is a wave of fluorescent color change. A small portable purple flashlight becomes a new favorite.

7.Criminal Investigation

Blood stains need to be matched with luminol.

Some Popular Science about Ultraviolet Light

1.UVA (Ultraviolet A)

Long wave UVA, its wavelength is between 315 ~ 400nm, can penetrate clouds, glass into the interior and the car, can penetrate to the dermis, lead to appear skin aging, wrinkles, the main cause of skin cancer. UVA can divided for UVA-2 (320~340M,) and UVA-1(340~400nm).

UVA-1 penetration is strongest. It can reach derma layer to make skin tanning, is the largest harmful to the skin. But also for  easy to overlook, especially not in the summer, UVA - 1 although weak intensity, still exists. Because of the amount of accumulated for a long time, it would cause skin damage, especially skin aging and relaxation, wrinkles, loss of elasticity, melanin precipitation.

UVA-2 and UVB can also reach the skin epidermis, which can cause sunburn, redness and pain, solar keratosis, and loss of transparency.

2.UVB (Ultraviolet B)

Middle wave UVB, its wavelength is between 280 ~ 315nm, will be absorbed by ozone in the stratosphere and would cause sunburn and skin redness, swelling, heat, and pain, serious, still can get blisters or peeling (similar to the symptoms of burn).

3.UVC (Ultraviolet C)

Short wave UVC, with a wavelength of 100~280nm, is shorter and more dangerous, but can be blocked by the ozone layer without reaching the surface of the earth, which is less harmful to human skin.

Note: Each person's tolerance for UV radiation, depending on the amount of sunlight accumulated to a certain limit, can cause different harm. UVC or high - intensity UVB and UVA exposed to industrial equipment, people can also cause damage to the surface tissue of the eye.

According to ISO-DIS-21348[4], UV radiation is classified as follows:
