UV-C germicidal technology has been recognised since the ‘60s as a valid physical method to control the growth and spread of microbes, viruses, pathogens, spores, and mould.

Light Progress uses UV-C as a physical disinfection method with excellent value for money, which is also ecological and, unlike chemical agents, works against all microorganisms without creating resistance.

How it works

Every microorganism has a specific level of resistance to UV rays, called a DOSE. The specific dose must be administered to obtain a suitable disinfection level, which is expressed as LOG REDUCTION (1 Log=90%, 2 Log=99%, 3 Log=99.9%, etc).

Certain microorganisms therefore require very low UV POWER, while others require more power to obtain the same level of elimination, or alternatively, they may require a longer exposure TIME.

These factors are essential in understanding UV technology:

  • Desired disinfection level (LOG reduction);
  • Target pathogen (and its DOSE);
  • UV Power and irradiation distance geometry;
  • Tempo di esposizione

We have always collaborated with large companies, with leaders in the food and healthcare industries, universities and research institutes, but also with construction companies responsible for building large infrastructures, transforming Ultraviolet Germicidal Technology into a real and practical solution. The action and performance of Light Progress products is guaranteed by third-party testing by reliable bodies, such as the Hygiene Institute of the University of Sienna, a renowned, highly qualified laboratory with which we have collaborated since the ‘80s, and many other Italian and foreign labs and entities.

Succes stories

Any UV application must be both effective and efficient, so that it can achieve a disinfection goal without burdening the client’s costs. Our team of engineers and our computational softwares are available to ensure the best UV solution for every specific need, so that every collaboration turns into a Success Story.

Ultraviolet rays are electromagnetic waves which are part of light. Electromagnetic waves are divided into three main wavelength bands, expressed in nanometers, nm: Ultraviolet rays (UV) 100-400 nm Visible rays (light) 400-700 nm Infrared rays (IR) 700-800,000 nm UV rays are in turn identified in three bands:

  • UV-A (315-400 nm) with tanning properties;
  • UV-B (280-315 nm) con proprietà terapeutiche e di sintesi della vitamina "D";
  • UV-C (100-280 nm) with germicidal properties.

UV-C rays (100-280 nm) have a strong germicidal effect and reach their maximum efficacy at the 265 nm wavelength. The germicidal effect of UV-C radiation covers bacteria, viruses, spores, fungi, moulds and mites; this is mainly due to the destructive effect of the UV-C rays on their DNA, which damage their reproductive system and prevent them from replicating.

Bacteria, Viruses, Spores, Fungi, Mould, and Mites are all sensitive to, and can therefore be eliminated with, UV-C light. Mircrobes cannot acquire resistance to UV-C light, unlike that which occurs using chemical disinfectants and antibiotics. UV rays are ecological. Polluting the environment is inevitable using normal disinfectants. Directly inhaling the vapours, or swallowing food products contaminated by any contact with said chemical disinfectants, can also give rise to a number of serious risks. In cases where chemical disinfectants cannot be eliminated (food, pharmaceutical, healthcare industries, etc.), using ultraviolet rays for disinfection allows a reduction in their use, with considerable economic savings and greater care for the environment, while maintaining and almost always improving the level of disinfection. UV-C light devices can be installed in environments and on machinery and be programmed to maintain the same level of disinfection day and night, guaranteeing ideal hygiene conditions, without highs and lows. On the contrary, chemical disinfectants are effective only during their actual use. Using LIGHT PROGRESS equipped luminaires, operating costs are negligible; it could be said that “LIGHT PROGRESS” UV-C systems do not require maintenance except for the normal replacement of the lamps. The cost/benefit ratio is considered excellent; the devices are both powerful and long-lasting. Hence the elimination of germs using UV-C technology is low-cost and highly effective compared to (or in combination with) other systems.

UV-C light genuinely works if properly applied and with the necessary precautions. The difference between a quality project, and an application that fails to bring the desired results, lies in the degree of knowledge about the subject, and level of experience acquired over time. Light Progress has been developing successful projects worldwide since 1987, and has built a client portfolio consisting of important companies in all fields requiring certified hygienic conditions to produce quality products and services.
