UVC lamps compared to LEDs

UVC lamps compared to LEDs

The first mercury-vapor lamps made their appearance around 1835. Besides producing visible light these lamps emitted ultraviolet radiation in the 254 nanometer range.

At the beginning of the 19th century it was discovered that this UV radiation had the property of inactivating bacteria. Today, it is common knowledge that UVC destroys the DNA and RNA in microbes, preventing them to replicate. As an example, the comparison with an egg is sometimes made. Break it and Humpty Dumpty can never be put together again.

In recent years a lot of research has been done into LED technology. Subsequently, it has become apparant that LED chips can also produce UVC and that there are benefits compared to lamps, e.g. they are not limited to the 254 nanometer wavelength emitted by mercury vapor. This is an enormous advantage because the 260 to 280 nanometer range that LEDs can produce is more lethal to bacteria and viruses than the 254 nanometer wavelength of lamps.

  • UVC LEDs are deadlier for bacteria and viruses than lamps
  • LEDs are not toxic while the mercury in lamps represents a health hazard
  • Unlike lamps, LEDs do not need to warm up
  • LEDs are energy efficient and have a longer lifespan

To sum up, with the cutting-edge LED technology in the COBstr Box you are well equipped to fight COVID 19 and other possible future viruses.
