It is easy to replace a lightbulb for most light fittings. You may remove the old light bulb to check whether it is a Bayonet or Screw-in type. You can find replacement light bulbs in supermarkets or on online stores. We recommend using LED light bulbs which save energy and last longer. Please note that most recessed ceiling light fittings use GU10 bulbs. If you have any questions, please feel free to send us a message through the app with photographs and details.
