UL certification: what does it offer the lighting industry?

UL certification

Certification granted by Underwriters Laboratories is one of the most important symbols of product quality and safety, setting standards worldwide. And although CE certification is still mainly granted in Poland, UL ensures competitiveness and opens doors for companies to the US and Canadian markets, which is of great importance for the lighting industry.

If you want to expand your market portfolio, go with UL. Awarded for over a hundred years, this certification is required in many countries before a product can be marketed. However, before a product can receive this certification, it undergoes a series of rigorous tests to confirm its ability to adapt safely and qualitatively to the market. Lighting with the UL symbol can be used virtually anywhere.

What is UL?

Underwriters Laboratories is an independent organization founded by William Henry Merrill in 1894. For 131 years, its specialists have been continuously testing products for safety, including resistance to mechanical damage, as well as the risk of electric shock and fire. Initially, the company focused on electrical and fire protection equipment. Today, it covers almost all product categories, including indoor and outdoor lighting.

However, UL certification is particularly important in the lighting industry, especially in the context of electrical installation safety and the use of luminaires in various, often extremely demanding environments – from domestic spaces to office buildings and industrial plants. Testing the resistance of lamps to overheating, as well as determining their failure rate, ensures that products can be freely traded around the world.

How to obtain a UL?

UL certification plays a significant role in reducing the risks associated with product use, contributing to increased user safety and minimizing costs related to potential complaints, failures, or financial losses. In practice, several types of UL markings are used.

The most well-known mark, “UL Listed,” confirms that the finished product has undergone detailed testing and meets specific safety standards. The “UL Recognized” mark, on the other hand, refers to components and subassemblies that can be used in complex devices and systems, provided they are properly integrated into the final product. For the lighting industry, this means that both entire luminaires and individual components, such as power supplies, LED modules, and wiring, can be certified.

The procedure for obtaining UL certification is multi-stage and includes a comprehensive evaluation of the product in terms of safety and quality of workmanship. The process begins with submitting the product to UL, specifying the appropriate standards by which the product is to be assessed.

Then, detailed laboratory tests are conducted, analyzing, among other things:

material resistance to high temperatures,
structural durability,
and behavior under emergency conditions.

For lighting products, the assessment of electrical safety, luminaire heat generation, and resistance to environmental factors is particularly important, especially for luminaires intended for outdoor use or in demanding industrial environments (extremely high or low temperatures, dust, humidity).

An essential element of the UL certification process is also an inspection of the production facilities, which ensures that the manufactured product series meet the standard approved during testing. Only after positive verification of all stages, the product receives the right to be marked with the UL mark.

UL certification costs and time

However, obtaining UL certification is an investment that must be carefully planned, both in terms of cost and duration of the process. In the case of lighting, the final price of obtaining certification depends, among other things, on the design of the luminaire, the number of components requiring separate testing, and the environment for which the product is intended. Different requirements apply to architectural luminaires intended for office or home interiors, and different requirements apply to lamps used in production or storage spaces.

Certification costs usually range from a few thousand to tens of thousands of dollars. In addition, expenses related to the preparation of complete technical documentation, possible design modifications, and mandatory inspections after the certificate is issued must be taken into account.

FAQ:
