Using these bollard lights is simple. First, make sure to have a licensed electrician install them as per the instructions in the box. They're designed to be mounted on solid surfaces like concrete paths or timber decks. When connecting the cables, use circular cable in the junction to keep the IP rating intact. For parallel or single connections, an IP68 connector is a good idea. These lights aren't suitable for dimming but work well with 2 - way switching and PIR or Microwave sensors. They can handle temperatures from -20 to 50 °C. However, if you live in an area with harsh weather or heavy rainfall, it's best to choose IP65 fittings unless you can protect these lights properly. To keep them in good condition, just give them a regular clean. If there are any problems within 3 years, you can get a replacement under the warranty.
