About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Circlio
Ice rain string of lights for outdoor use

Product description from the manufacturer

The Circlio Outdoor Ice Rain String Lights are versatile LED string lights with 200 LEDs over a length of five meters, specially designed for indoor and outdoor Christmas lighting. They are ideal for decorating trees, balconies, windows, or gardens and create a festive atmosphere with customizable lighting effects. The product comes with a five-meter connection cable, hooks, and cable ties, which makes installation easy.

In testing, the LED Christmas lights impressed with their smart DIY control via the Surplife app, which allows for individual color adjustments, as well as the two-color light change with warm and RGB light. Advantages include the bright and radiant LEDs, 17 lighting modes with adjustable flashing speed, and adjustable brightness in four levels (25%, 50%, 75%, 100%) including a memory function. The waterproof design makes them robust for outdoor use.

However, the limited remote control, which only includes eleven modes, was a negative point—for more, the app must be used.

Overall, the outdoor string lights offer good value for money for creative Christmas decorations, but could be more robust in terms of operation.

  • Intelligent app control
  • Waterproof
  • Many lighting modes
  • Adjustable brightness
  • Integrated memory function
  • Limited remote control
  • App required to use all modes

In our opinion, Circlio’s Eisregen string lights impress from the moment you first handle them thanks to their attractive appearance. The color selection—with warm white and RGB options—and the even positioning of the 200 LEDs create an aesthetically pleasing presence that blends seamlessly into festive decorations, whether indoors or outdoors. The overall workmanship is very good: the cables are flexible but durable, and the LEDs appear to be precisely embedded, with no loose parts or visible defects. In terms of stability, the product appears robust, thanks to silver-plated components that prevent rust and make it suitable for outdoor use. There is no explicit information from the manufacturer about the sustainability of the product, but the use of durable materials such as waterproof coatings (IP65 for the string lights, IP44 for the controller) indicates longevity. Overall, the LED Christmas lights feel high-quality and inspire confidence in their durability. For end consumers, this means a reliable string of lights that not only looks good but is also easy to use.

*The maximum score is 100 points

Practical testing has shown that Circlio’s Eisregen string lights largely live up to the manufacturer’s advertising promises, albeit with slight limitations. The lighting functions flawlessly: all 200 LEDs shine evenly and brightly, without failures or flickering, confirming the promised brightness and luminosity. The cable length corresponds exactly to the specified five meters plus connection cable, which allows for flexible outdoor installation. The water resistance was particularly impressive: no malfunctions occurred during and after a simulated rain and splash test – however, the plug must remain dry. The plug connections showed slight wear after repeated plugging and unplugging, but continued to function perfectly. The remote control functions work reliably, including mode changes and brightness adjustment, but there were sporadic delays or lack of response from the LED light chain, which makes the app control a recommended alternative. Overall, Circlio delivers on its promises for Christmas lighting, with a focus on versatility and robustness, and is well suited for discerning users looking for smart Christmas decorations.
