If your outdoor lights are no longer responding and you suspect an issue with the power supply unit (PSU), unplug the power supply from the wall socket and contact Philips Hue.
Do not touch the power supply in wet conditions. If the cable or plug are wet, first cut the main power to the socket, and then unplug the power supply. Do not leave any plugs or connectors of your outdoor lights open — use the supplied plastic caps to cover them. If you don’t have the original plastic caps, you can wrap the connectors in plastic.
Note that we have launched a voluntary replacement program for some PSUs. Please check if your PSU is eligible for the voluntary replacement.
