Had to modify wiring to fit in with replacement filament lamp. Not earthed either. Quality very good , heard that if these are. Left on that the inverters pack in , so probably ok for security light coming on and off ... But not good for prolonged use.
Use these around the garden with apple devices , surprisingly good Bluetooth range. Only annoying thing is never sure if they are power off when not in use. Have to keep power on them to make sure they are always fully charged.
