Circle Uvc Light Round Ozone Free Or High Ozone Uvc Germicidal Bulb

UVC is the shortest wavelength of the three forms of UV. The shorter the wavelength, the more harmful the UV radiation. However, lucky for us, UVC isn't able to penetrate earth's atmosphere. So while UVC is the most dangerous because it's the shortest wavelength, it's not a risk to the typical person because the sun's natural UVC emissions don't penetrate skin. Remember, they actually do not even penetrate earth's atmosphere naturally at all. UVC is absorbed completely by the ozone layer.

This is not to say that UVC isn't dangerous. Although naturally occurring UVC doesn't permeate earth's atmosphere, inorganic sources of UVC radiation exist and are dangerous when not used properly. So, the people who need to be concerned about UVC radiation are those working with these man-made sources of UVC, like welding torches, mercury lamps, and, you guessed it, germicidal UV-C lighting.

Advantages:

High efficacy: UVC peak at 253.7nm for disinfection

Long life: specail coating for longer life than others

Installation: can be used horizontally and vertically

Environmental: minimized amount of mercury

Stable uv maintenance: 80% uv intensity maintainable

High ozone type could be made

special cap is optional

What is UV lighting?

Ultraviolet light (UV) is a type of naturally present electromagnetic radiation that is in sunlight and actually makes up approximately 10% of the total light generated by the sun. UV light is electromagnetic energy with wavelengths shorter than visible light but longer than x-rays (see image below).

The wavelength of this light ranges from 10nm to 400nm and is classified into three sub-bands; UV-A (near), UV-B (middle), and UV-C (far).

UV light with wavelengths less than 290nm is considered to have “germicidal” properties (more on this below). Earth's atmosphere absorbs ultramagnetic radiation with wavelengths less than 290nm, meaning that most of the UV-C and UV-B generated by the sun are blocked by our planet's ozone.
