WHAT UVLON IS, THE BENEFITS IT OFFERS, AND WHY IT WILL BECOME A STANDARD OF SAFETY AND QUALITY FOR UV-C SYSTEMS
 
In the food, pharmaceutical and medical sectors—and more broadly in air treatment—UV-C technology has become a key solution for ensuring process safety and hygiene. 
Designed to become the new standard for UV-C applications, UVLON® is a heat-shrink protective sleeve applied directly to the glass of our UV-C lamps, combining strength, reliability and performance. 
In this article, we explain what UVLON®  is and the benefits it delivers. 

WHAT IS UVLON
UVLON® is a protective sleeve made of FEP (Fluorinated Ethylene Propylene), developed and registered by Light Progress for UV-C lamp protection. 
FEP is an inert, transparent fluoropolymer approved for food contact according to FDA regulations, making it suitable for applications in the food, pharmaceutical and medical sectors. 
The sleeve allows high UV-C wavelength transmission, preserving treatment effectiveness without compromising system safety. 
The FEP coating makes lamps safer to handle, allowing bare-hand contact during installation and maintenance, while providing a smooth surface that is easy to clean and resistant to aggressive and chemically demanding environments. 
UVLON® also protects lamps from thermal fluctuations, particularly low temperatures, helping maintain optimal performance and improving overall operational reliability. 

To ensure uniform and controlled application, Light Progress has developed a proprietary automated machine that performs fully mechanized and precise heat-shrinking. This exclusive process increases protection robustness and makes Light Progress lamps a global benchmark for reliability and durability. 

In UV-C systems, preventing lamp breakage is not optional—it is a prerequisite for safe operation. 
For this reason, starting in 2026,UVLON® becomes the standard: lamp protection is no longer an option, but an integral part of UV-C systems. 

THE ADVANTAGES – ROI, efficiency and compliance
 
Lower costs, greater continuity 
By protecting the lamp,  UVLON®  reduces breakage, replacements and downtime. The result is longer lamp life and an immediate return on investment. 

Uninterrupted production 
In the event of breakage, the sleeve contains glass fragments and prevents contamination, rejects and line shutdowns—an essential requirement in regulated sectors such as food, pharmaceutical, medical and HVAC. 

Compliance and brand protection 
 UVLON®  supports compliance with international standards (FDA, IP44) and reduces the risk of non-compliance, product recalls and legal disputes, directly protecting brand reputation. 

Reliable performance in harsh environments 
The FEP sleeve resists wear, aggressive chemicals and demanding operating conditions, ensuring consistent performance and reducing unplanned maintenance.

AN OPTION TODAY, A STANDARD TOMORROW

At present, UVLON® is offered as an optional accessory, available together with UV systems. However, for several applications in the food, pharmaceutical, medical, and HVAC/air conditioning sectors, Light Progress already supplies UV-C lamps with UVLON® protection as the default configuration. From 2026, this option will become standard: UVLON® will no longer be an accessory, but an essential and integrated component of our solutions.

REGULATIONS AND RESPONSIBILITY
UVLON® makes UV-C lamps safer to handle, install and clean. Unlike bare glass, the protective sleeve allows bare-hand handling and effective cleaning, even with chemical agents. 

For machine manufacturers, this means more robust and easier-to-integrate solutions. 
For end users, it means greater safety, reduced maintenance and higher operational reliability.

ACCURACY IN PERFORMANCE CALCULATIONS
It is important to note that our microbial inactivation calculations and UV-C system performance software already take the use of UVLON® into account. 
As a result, efficacy values remain unchanged and fully reliable. 
Integrating UVLON® as a standard adds value and eliminates risk.

F.A.Q.

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 really does work when applied correctly and with the necessary precautions. The difference between a quality project and an unsuccessful application is in-depth knowledge and experience gained over time. Since 1987, Light Progress has been carrying out successful projects all over the world and has acquired a clientele of major companies in all sectors that require verified hygienic conditions to produce quality products and services.
