Once the wiring is already in place, e.g. you are replacing an existing outdoor light, installing a new outdoor light is an easy task. Follow our guide for a successful installation.

Step 1

Turn Off Power

Turn Off Power

Turn the power off at the mains and ensure that everyone at home is aware of the danger of turning the power back on while you work. Failure to do so may result in a serious accident during the installation process. Tip: if you are installing a light with a motion detector, make sure the sensor will not be pointing towards an area where there is a lot of daily activity, such as the main road outside your property. If it is positioned in this direction, the light will be set off on a regular basis unnecessarily.
