There are significant differences between UV amalgam lamps and ordinary UV lamps in many aspects. These differences are mainly reflected in the working principle, performance characteristics, application range and use effects.
Ⅰ. Working principle
● Ultraviolet amalgam lamp: An amalgam lamp is a type of ultraviolet germicidal lamp, which contains an alloy (amalgam) of mercury and other metals. Under voltage excitation, amalgam lamps can emit stable ultraviolet light with wavelengths of 254nm and 185nm. The existence of this alloy helps reduce the impact of rising lamp temperature on ultraviolet output and improves the output power and stability of ultraviolet light.
● Ordinary ultraviolet lamp: Ordinary ultraviolet lamp mainly generates ultraviolet rays through mercury vapor during the discharge process. Its spectrum is mainly concentrated in a shorter wavelength range, such as 254nm, but usually does not include 185nm ultraviolet rays.
Ⅱ. Performance characteristics

|
Ordinary UV lamp |
| UV intensity | Higher, 3-10 times that of standard UV lamps | relatively low |
| Service life | Longer, up to more than 12,000 hours, even up to 16,000 hours | Shorter, depending on lamp quality and working environment |
| Calorific value | Less, saves energy | Relatively high |
| Range of working temperature | Wider, can be expanded to 5-90℃ | Narrow, limited by lamp material and heat dissipation conditions |
| Photoelectric conversion rate | Higher | Relatively low
|
Ⅲ. Application scope
● Ultraviolet amalgam lamp: Due to its high power, long life, low calorific value and wide operating temperature range, amalgam lamps are widely used in situations that require efficient sterilization and disinfection, such as hot spring water, sea water, swimming pools, SPA pools, Water treatment systems such as landscape pools, as well as air conditioning system disinfection, air purification, sewage treatment, exhaust gas treatment and other fields.
● Ordinary UV lamps: Ordinary UV lamps are more commonly used in situations that do not require high UV intensity, such as indoor disinfection, air purification, etc.

Ⅳ. Effect
● Ultraviolet amalgam lamp: Due to its high UV intensity and stable output, amalgam lamps can more effectively kill bacteria, viruses and other microorganisms, and have a long service life and low maintenance costs.
● Ordinary ultraviolet lamp: Although it can also play a certain role in sterilization and disinfection, the effect may not be significant enough in comparison, and the lamp needs to be replaced more frequently.
To sum up, there are significant differences between UV amalgam lamps and ordinary UV lamps in terms of working principles, performance characteristics, application range and use effects. When selecting, comprehensive considerations should be made based on specific needs and scenarios.
