UV-STICK-SCR / UV-STICK-SCR-UL is composed of:

UV-STICK-SCR is a compact size device with a great germicidal power. This series is available both in Stainless Steel and in Anodized Aluminum and includes lamps from 50 to 160 cm length.
Inside its body, with IP55 protection, UV-STICK-SCR contains a special ballast which optimize lamps output and life.
Every device has its own reflector, parabolic or not, to increase Germicidal Irradiation and direct all UV-C rays towards the surface that has to be treated.
UV-STICK-SCR it is made with high quality material and very resistant components, and for these reasons it works perfectly in stressing environments (high Humidity, Low or High Temperature).
Its design allow an homogeneous disinfection treatment even inside small and very inaccessible space, such as in between coil fins and inside filters texture.
Serial connection of more than 10 devices is possible just through 1 single power supply cable, and installation is easy in combination with the Light Progress original adaptable mounting kit.


Applied inside AHU (Air Handling Unit), UV-STICK-SCR eliminates viruses, bacteria, moulds, spores and inhibits their dangerous proliferation in Air Conditioning Systems.
UV-STICK-SCR is the simplest, most flexible and more efficient device to improve Indoor Air Quality (IAQ), but also save energy consumption and maintenance costs in HVAC Systems.
Its germicidal power cleans and purifies all surfaces inside A.C., where usually an unpleasant biofilm covers and adheres on every mechanical component, penetrates inside every little interstice, grow in between coil fins, settles on water tanks and spreads freely all over the air along A.C. ducts.
Legionella Pneumophila, Tuberculosis, Flu Viruses and other common pathogens are usually free to proliferate inside HVAC, with Volatile Organic Compounds (VOCs) cause of Asthma, Allergies, the so called “Sick Building Syndrome” and “Monday Fever”. In hospitals risks increase with Cross Contamination and Healthcare Associated Infection.
UV-STICK-SCR application is important not only for IAQ, but a cleaner AC system is also more efficient from an economic point of view, with less operative and maintenance costs. As a matter of fact, using UVGI the need of filters replacement and chemical clean of inner surfaces is less necessary than usual.
Other benefits are the optimized level of energy consumption, reduction of air flow losses, in few words with UV-STICK-SCR you have better comfort for people in the building, saving money.




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.
