UV-lamps: disinfection of surfaces was never before easier!


What a lot of people do not know: UV-lamps are perfectly suited for disinfection! They render micro-organisms such as viruses, bacteria, yeasts and micosis in the water, in the air and on surfaces harmless!

However, even more is possible with UV-light – conditional on the light’s wavelength. Let us explain to you what that is and what it depends on!



Therefore, we will outline the rough basic information (as a kind of simple description):

The human being can perceive many colors and much of light. However, there is light invisible for people.

For example, the infrared light which is connected to the visible red light. In technical lighting, the electro-magnetic radiation of infrared light is used for sensors (see passive infrared sensor technology).

On the other hand, you have ultraviolet light (=UV – or also called black light) connected to the visible violet light.

UV-light is subdivided into the classification of UV-A, UV-B and UV-C-light. This classification depends on the wavelength of light. We know UV-A and UV-B-radiation from the sun – it causes the undesired sunburn.

UV-A-light is quite close to the visible violet light – colloquially also called black light. It has less energy and is applied for the hardening of photopolymers, in photochemistry or also in reprography. UV-A-light is also used for insect control.


Thanks to its antibacterial effect (often in combination with UV-A-light) UV-B-light is often used in light therapy. UV-B-light can relieve itching of certain skin diseases and can also help people suffering from actinic dermatitis.


UV-C-light has short wave infrared radiation and provides most of energy. This is the reason why UV-C-light is used in systems for the removal of bacteria, i.e. disinfection systems. The range of application goes from medical equipment to air, water and food. UV-C-light kills viruses, germs and bacteria. At the same time this light is uncritical for the human being – when applied correctly. Viruses and bacteria are much smaller than the human cells and thus can be destroyed by UV-C-light. Hence, UV-C-light is applicable for combatting tuberculosis viruses and influenca virus infections; it is even used to combat the multi-resistant germ staphylococcos found in hospitals.

Disinfection with UV-C-Lamps: Advantages

Compared to liquid detergents, disinfection with UV-C-light is made without any touch of surfaces. A very eco-friendly method because there is no need to use chemical agents. In addition, disinfection with UV-C-lamps preserves your surfaces – there is neither the risk of having residues nor discolouration. Surfaces or devices disinfected with UV-C-lamps are immediatly ready for further use.

What about health security when disinfecting with UV-C-light?

Since a while, UV-C-radiation is successfully used for the fight agains germs – however, the correct application must be safeguarded. There are still not enough studies about the consequences of exposition to UV-C-radiation for the human being, though also notice was given about cases of skin- and eyes irritation due to improper long-term exposition.

The risk is low for most of the devices as they are closed systems. Nevertheless, the instruction for use has be followed with utmost accuracy.  During use of the luminaires, the area of application has to be left, windows and doors need to be closed.  After disinfection, light must be switched off. It is recommended to also carefully air the zone of disinfection.

Please find more information on influence of UV-C-lamps on the human being in the information sheet of the European Commission.

Should you have any questions or need advice for application of your UV-C-lamps, please directly consult the manufacturer or a specialist.

 For safe operation, the safety instruction of the lamps’ manual must be followed carefully.
