We supply a 24 Volt screw in E14 LED or Filament bulb to fit all our lamps. It is a specialist bulb for use with our ceramic lamps as they are fitted with a 24 Volt transformer plug for safety. It will fit and work with all shapes and styles of our lamps, including animal and toadstool shapes. It will work with a lamp that has either a black OR a white plug. Please note only use a 24 Volt bulb and not a 240 Volt bulb as this could effect the transformer plug.
