Using your CHESTER LED wall light is easy. First, make sure to have it installed by a licenced electrician as per the instructions in the box. Once installed, you can control the light using the on/off switch on the back plate. It's suitable for 2 - way switching and can work with PIR or Microwave sensors, so you can set it up according to your needs. Keep in mind that the light is not suitable for dimming. For the best performance, use it in an ambient temperature between - 20 and 50°C. In terms of maintenance, simply clean the clear PS shade and the powder - coated white aluminium back plate with a soft, dry cloth. The light comes with a 2 - year replacement warranty, so if you face any issues, contact the support team.
