Holiday light decorations, such as Christmas lights, bring a magical atmosphere to homes, but choosing the wrong ones can pose serious risks, including electric shocks, fires, or property damage. Therefore, it is crucial to prioritize safety principles over aesthetics when making your purchase.
Basic standards and requirements
- 1. CE marking
Lights sold within the European Union must bear the CE marking, confirming compliance with European safety standards. This marking should be visible, durable, and permanent. - Technical standards
Products should comply with the PN-EN 60598-2-20 standard, which applies to string light sets. Compliance with this standard ensures, among other things, that the materials used in the lights are flame-resistant and that the design is safe for use. - Material quality
Cables and casings of the lights should be made from materials resistant to mechanical and chemical damage. Cable insulation must protect against electric shocks and short circuits. - Weather resistance
Lights intended for outdoor use should be waterproof and resistant to UV rays. Protection class ratings, such as IP65, guarantee safe outdoor usage. - User manual
Every product should include a clear user manual with information on proper use, maintenance, and warnings about potential hazards.

Why choose safe products?
Inadequate lights, especially those from unknown sources, can lead to severe accidents, including electric shocks or fires. Low-quality lights often have poor insulation, lack weather resistance, or come with incomplete technical documentation.
RCC – Ensuring the safety of your holiday decorations
At the RCC Research and Development Center, we conduct comprehensive tests on Christmas lights available on the market to ensure consumer safety and product quality.
What do we check at RCC?
- Compliance with standards
We verify whether the lights meet the requirements of the PN-EN 60598-2-20 standard and whether they bear the CE marking. - Material and craftsmanship quality
We test casings and electronic components for resistance to mechanical and chemical damage, as well as to weather conditions. - Safety of use
We examine insulation quality, protection against electric shocks, and the sealing of outdoor fixtures. We also analyze the flame resistance of materials used in the construction. - Documentation clarity
We ensure that products come with manuals containing essential information for proper use.
Christmas lights testing results
Market inspections of Christmas lights often reveal issues such as missing technical parameter information, inadequate cable insulation, or the use of low-quality materials. While many products bear the CE marking, it does not always guarantee full compliance with applicable safety standards.

What products to choose?
We encourage consumers to rely on trustworthy information and avoid products of unknown origin. Thanks to RCC testing, you can be confident that the products have undergone detailed safety checks, ensuring your holiday decorations are both beautiful and safe.
