UV-Downlight222 is an embedded far UVC device developed by MYSOTER with indirect lighting. It is equipped with the world’s top spectrum technology—Japan Ushio Care222® module, emiting pure 222nm far UVC. UV-Downlight222 with common downlight size can quickly replace the original lighting installation without rewiring. At the same time, it has the function of indirect lighting, soft and uniform light, avoic打ng glare and health hazards.


  • Low energy consumption, energy saving, eco-friendly, no noise
  • Long lifespan
  • Replace the high labour cost
  • High effect, and low cost

Composition of far UV-C lamp

mysoter’s Far UV-C lamp consists of a tube filled with a gas called krypton chloride. This gas has the unique property of emitting UV-C-light at 222 nm when a discharge is applied to it. When the lamp is turned on, electricity creates a discharge that excites the gas and after a short period of time, UV-C light at 222 nm is emitted.

A Far UV-C lamp without a filter emits light in a narrow band around a 222 nm peak, but also releases secondary emissions around 235 nm and 250 nm. These extra wavelengths are known as side-bands or side-emissions. These wavelengths are harmful to humans, but the unique and patented safety filter in UV222 blocks them before they are emitted into the surrounding environment.

The safety filter technology in the lamp from Ushio care222 is a thin filter that only lets through light at around 222 nm and blocks all other unwanted radiation. It works much in the same way as sunglasses with UV protection, blocking the UV radiation from passing through and enterin
