UV-A encompasses wavelengths between 315 and 400 nanometers, while UV-C includes wavelengths from 100 and 280 nanometers. UV-B wavelengths fall in between at 280 and 315 nanometers. Both UV-A and UV-C are not visible to the naked eye, so it can be a bit counter-intuitive as you cannot visually see the difference between these two types of UV Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.

UV-A, which is also called "blacklight" or "Long Wave" UV, spans wavelengths between 320 and 400 nm. It is the closest UV radiation to visible light. Almost all of the ultraviolet radiation that makes it through our atmosphere to Earth's surface is UV-A. UV-B waves, with wavelengths between 280 and 320 nm, carry more energy than UV-A waves.

The Inova X5 UV flashlight is our choice for the best all-around ultraviolet utility light. It’s compact, fairly inexpensive, and a very nice design. One great thing about this light is that it has 5 ultraviolet LEDs, so it puts out a large volume of light compared to its competition. The 5 LEDs have a nanometer rating from 365-400 nm, so it
True fluorescent color is visible in ultraviolet and with visible light, but the color does fluoresce under UV light. This means that UV light excites the energy in the molecules and results in a more vivid color. Manufacturers have also developed daylight fluorescent pigments (DFP) that provide the same vivid colors that UV light produces. . 250 850 938 91 242 859 616 140
