Using this wall light is simple. First, make sure you have a licensed electrician install it as per the instructions in the box. Once installed, it can be used for 2 - way switching and can work well with PIR and Microwave sensors. However, don't try to dim it as it's not suitable for that. When it comes to maintenance, keep it in an environment where the temperature is between - 20 and 50°C. If there are any issues within 2 years, you can get a replacement under the warranty.
