UV Light Bulbs Buying Guides

 

Principle of UV light disinfection

The principle is using the released ultraviolet rays to inactivate bacteria and viruses. Which achieve the effect of sterilization and disinfection. The specific working principle is the light source of the ultraviolet lamp. At present, there are two main light sources: gas discharge light and solid-state light.

The most available gas discharge light sources are low-pressure mercury lamps. Its working principle is the same as that of a fluorescent lamp. The mercury vapor generates ultraviolet rays by energizing the mercury atoms. Low-pressure mercury vapor generally produces 254 nm UVC and 185 nm UVD ultraviolet rays.

Among them, 254 nm short-wave ultraviolet (UVC) destroys the molecular structure of the DNA and RNA. It causes cell death, and achieves the effect of sterilization and disinfection.

Although 185 nm UVD ultraviolet rays do not have effective sterilization effect. It can decompose oxygen in the air and generate ozone. The strong oxidizing property of ozone can oxidize and decompose the enzymes. Without these enzymes, bacteria cannot survive. When choosing an ultraviolet lamp, you will find that almost all lamps have or do not have ozone function. This is actually determined by the working principle of the ultraviolet lamp.

The other solid-state light source refers to the UV-LED light source. Although the volume is small, the efficiency is much lower than the low-pressure mercury lamp above. And due to cost issues, the price is also very expensive. Generally used in water purifiers , Air conditioning and other equipment.

How much power is the most suitable UV lamp?

After talking about the principle of the UV lamp, then we must consider the specific choice. Regardless of appearance, the most critical selection criterion is wattage. Then how much wattage you should chose?

Generally speaking, 1 cubic meter of UV lamp should not be less than 1.5W. So, assuming your bedroom is 20 square meters and 3 meters high, you need a 40W ultraviolet lamp for your bedroom.

Another thing is the material of the bulb. At present, there are two main glass materials: quartz glass and high boron glass. The transmittance and radiation of quartz glass are higher than high boron glass. And the penetration of short-wave ultraviolet rays is weak, so be sure to choose quartz glass.

Besides, the shape and installation method of the lamp should also be considered. We recommend to choose beautiful ultraviolet lamps. When in use, the ultraviolet rays can be placed on a high position such as a table for irradiation.

Also, there are also some smaller portable UV lamps on the market. Although the power is lower, it can be used to disinfect small spaces such as closets and refrigerators. It is also a good choice.

Is the ozone function necessary?

Generally, furnitures and sundries will block the transmission of ultraviolet rays. So, we recommend that you choose ultraviolet lamps with ozone. Ozone can flow through the air to completely sterilize some dead spots. However, ozone is harmful to the human body. After the disinfection complete, open the window for 30-60 minutes until there is no pungent smell of ozone.

How long does the UV bulb need to be disinfected?

Usually a brand-new 30W ultraviolet lamp has an intensity of 90-100μW/cm² at 1 meter. The research report pointed out that UVC with an intensity greater than 90 μW/cm² can kill the virus in 60 minutes. So, you can follow the maximum dose for 60 minutes of irradiation for disinfection.

But whether it is ultraviolet light or ozone, long-term exposure can cause certain damage to the items. Thus, the exposure time is not suitable for too long. Besides, the ultraviolet lamp has a life span. As you use it, take it extend the single irradiation time.

What should I pay attention to when using UV lamps?

Ultraviolet light can inactivate bacteria and viruses. And, it is also harmful to the human body. So when using it, it should not be irradiated to the human body! When buying, try to choose a UV lamp with delayed start, human body induction and other functions. Make sure to use it as safe as possible.

If you choose a UV lamp with ozone function, remember to open the window for 30-60 minutes after use. Until smelling no pungent odor.

Besides, the lamp tube contains mercury vapor. So pay attention to safety when using and storing. Do not break the lamp tube, mercury vapor is also quite harmful to the human body.

After using the UV lamp, we recommend to wipe the surface of the lamp tube to remove dust and other dirt. After all, the penetration ability of ultraviolet rays is too weak. And, as the life of the UV lamp, we recommend you to replace the lamp . Generally speaking, its life span is about 8000 hours, but you can’t wait for its life to run out before replacing it. If the frequency of use is not particularly high, we recommend to replace it every one to two years.

 

Conclusion

The importance is personal hygiene, frequent ventilation, and develop good habits. You should maintain a clean and hygienic environment indoors.
