Is mercury or uvc better for UV lamps?

We all know that UVC lamps are widely used in daily life, like some specific areas, UVC lamps or become an essential part. So UV lamps generally choose mercury lamp or UVC is good? 

The choice of UVC lamps depends on specific application scenarios and needs. Mercury lamps and UVC LEDs are two different types of UV light sources, each with their own advantages and disadvantages. 

Mercury Lamps: Advantages: Relatively low cost, especially in mass production. The technology is mature and widely used. Performs well at high power outputs.

Disadvantages: Contains elemental mercury, which may cause environmental pollution if broken. Requires warm-up time to achieve maximum efficiency. Relatively short service life, usually around a few thousand hours. Large size, not easy to miniaturize design. 

UVC LED: Advantages: Contains no mercury and is more environmentally friendly. Fast start-up, no warm-up time required. Long service life, some up to tens of thousands of hours. Small size, suitable for integration into various devices. Low energy consumption, more energy efficient.

Disadvantages: Costs are currently high, especially for high power UVC LEDs. Luminous efficacy still falls short of traditional mercury lamps, but the technology is improving. 

The main considerations for choosing which type of UVC lamp to use are as follows: 1. Cost budget: If cost is an important factor, then traditional mercury lamps may be a more economical choice. 2. 2. Environmental impact: Considering environmental protection, UVC LEDs are preferred because they do not contain mercury. 3. Application scenarios: UVC LEDs are more suitable for applications that require portability, fast response or long run times. 4. Usage requirements: Specific technical parameters such as disinfection intensity, coverage area, etc. are also a deciding factor. In short, when choosing a UVC lamp, it should be based on the actual needs and conditions. With the development of technology, the cost of UVC LEDs is gradually decreasing and their performance is improving, so they may become the preferred solution for more occasions in the future.
