Low-pressure lamps are very similar to a fluorescent lamp, with a wavelength of 253.7 nm (1182.5 THz).
The most common form of germicidal lamp looks similar to an ordinary fluorescent lamp but the tube contains no fluorescent phosphor. In addition, rather than being made of ordinary borosilicate glass, the tube is made of fused quartz or vycor 7913 glass. These two changes combine to allow the 253.7 nm ultraviolet light produced by the mercury arc to pass out of the lamp unmodified (whereas, in common fluorescent lamps, it causes the phosphor to fluoresce, producing visible light). Germicidal lamps still produce a small amount of visible light due to other mercury radiation bands.
Germicidal lamps are used to sterilize workspaces and tools used in biology laboratories and medical facilities. If the quartz envelope transmits wavelengths shorter than 253.7 nm, they can also be used wherever ozone is desired, for example, in the sanitizing systems of hot tubs and aquariums. They are also used by geologists to provoke fluorescence in mineral samples, aiding in their identification. In this application, the light produced by the lamp is usually filtered to remove as much visible light as possible, leaving just the UV light. Germicidal lamps are also used in waste water treatment in order to kill microorganisms.
Short-wave UV light is harmful to humans. In addition to causing sunburn and (over time) skin cancer, this light can produce extremely painful inflammation of the cornea of the eye, which may lead to temporary or permanent vision impairment. It can also damage the retina of the eye.
For this reason, the light produced by a germicidal lamp must be carefully shielded against direct viewing, while reflections and dispersed light is not an issue. A February 2017 risk analysis of UV-C lights  concluded that ultraviolet light from these lamps can cause skin and eye problems.
TIPS ON HOW TO USE
Mount as high as possible on the wall, The light should face up, not down. Leave a gap of 6inch from the ceiling.
Room to be emptied of habitants, switch on air-cond, fans or any ventilations fans, let the air flow in the room circulating. Switch on GERMICIDAL light & it will automatically burn any germs that are flowing in the air. Leave the room immediately. Let it be for few hours then switch off light or unplug it.
Make sure the lights or plug are out of reach from childrens.
What is ozone and where is it in the atmosphere?
