Question about Paulmann SimpLED

The description and installation instructions on the manufacturer's website state that it is IP20 protected.

Here what IP20 means:
Most indoor luminaires are marked IP20 (IP20 lamps). The abbreviation IP stands for "International Protection" a term that describes the suitability of electronic devices for various environmental conditions and additionally indicates whether a potential hazard (e.g. a short circuit) arises when using the device.

The IP code "20" is composed of two code numbers:

The first digit "2" stands for "Protected against solid foreign bodies with a diameter of less than 12.5 mm" as well as "Protected against access with a finger".
The second digit "0" indicates that the electrical device is not protected against water and moisture.
What sounds complicated is actually quite simple: in the case of a luminaire with protection class IP 20, fingers cannot reach components through which voltage is conducted. However, the luminaires or the electrical devices are not waterproof and dustproof and are therefore only suitable for use in dry indoor spaces - for example, the living room or bedroom.

Tip: Luminaires with IP 20 protection are not suitable for use in bathrooms and kitchens. It is better to use luminaires with a protection rating of IP 65 or higher.

So I would not use the LED strip outdoors or only in a protected area.
I hope I was able to help.

Is not recommended. The connectors are not insulated.
