First, choose the category
 
There are multifunctional germicidal light on the market, as well as LED household germicidal light.
 
LED household germicidal light has a long life, and the current sterilization efficiency is high, high power; the wavelength is between 265nm and 280nm. But the price is more expensive. LED household germicidal light has the best prospects, but it is currently suitable for disinfection in small spaces. Due to the high price in other scenarios, it is possible to choose to purchase.
 
The multifunctional germicidal light has high power and can kill bacteria such as Escherichia coli and spores on the surface of the object. It is expensive and more suitable for medical institutions, large shopping malls, airports, airplanes, train cars, etc. Suitable for procurement by government medical institutions. Generally speaking, the prospect of multifunctional germicidal light is the best, and the price is slightly higher. But the bactericidal effect is significant. More suitable for purchase.
 
Second, choose materials
 
Most of the LED household germicidal light on the market use quartz tube and high boron glass.
 
Quartz tube LED household germicidal light:
 
1. The material with the highest ultraviolet transmittance can transmit more than 90% of 253.7nm ultraviolet rays;
 
2. High ultraviolet intensity, long life, low light decay, good sterilization effect, lamp life is generally greater than 8000 hours.
 
High boron glass LED household germicidal light:
 
1. High boron glass can only transmit about 50% of 253.7nm ultraviolet light;
 
2. Its ultraviolet radiation intensity is small and its life span is short. Several established international companies are doing well, such as Philips/OSRAM.
 
Third, choose whether to contain ozone
 
Quartz LED household germicidal light, divided into ozone and ozone-free. Need to make a choice for specific use scenarios. Such as disinfection box or warehouse goods disinfection, need to use ozone. Doped quartz glass is used for ozone-free ultraviolet lamps; natural quartz glass is used for ozone-containing ultraviolet lamps; synthetic quartz glass, which has a higher cost, is used for LED household germicidal light with higher requirements. General household use.
