What Are The Disadvantages Of Sanitizing Using UVC light?
A room that has been disinfected with UVC can have some lingering odors; these odors will dissipate once the room is aired out. This odor is the result of the breakdown of dust during disinfection. 80% of dust in a room consists of dead human skin and hair cells. As these cells break down, they release chemicals which cause these odors.
UVC rays are a high intensity light and direct exposure is harmful to all living organisms (humans, pets, plants), not just bacteria and viruses.
We purchased Carhartt safety sunglasses that were labeled as 99% protection for UVA/B/C protection.
No human, pet or plant should be in a room that is being sanitized with UVC light blub or room lamp.
Keep portable UVC wands faced downward towards the surface you are sanitizing.
When sanitizing an entire room with a bulb or lamp, use a timer or remote switch so you can turn the light on and off from a safe distance.
If you need to manually turn on a UVC light bulb, wear clothing that covers all exposed skin and protective goggles for your eyes.
If you are concerned about being in close proximity to UVC rays, you might consider Far-UVC lights and wands. They emit lower doses of UVC 200-222 nm, which cannot penetrate the outer dead (non living) layers of human skin or the eye, but are still effective at inactivating bacteria and viruses.
You must faithfully follow the manufacturers’ instructions on light-source distance, exposure time and safety precautions for any device you purchase.
UVC light is much more intense than sunlight. Direct exposure can causes skin cancer and and eye problems.
Only organisms in direct line of the UVC light rays will be sterilized (light can’t turn corners or go around objects)
Rotate the light’s location in a room to reach all areas, or use several lights at different angles
The further away an object or surface is from the light, the more exposure time is needed for sterilization. Objects that are further away from the light will still be sanitized, they just need a longer exposure period if they are further away.

The deal with those lights and even the 1200 dollar lights is they are literal scam modern snake oil. The amount of output from those lights is useless for virus elimination as a much higher, longer exposure to real UV is needed.
And as surfcast illustrated, real UV in high amounts that's needed is dangerous to people and pets.

And a premise of UV isn't real UV. Either have UV at high doses or not.

Those may be good for reading lamps however or looking for bodily fluids in motel rooms. If you like purple lighting.
