The right bulb for the light should be selected carefully. The use of Led lights with the maximum power of 9W is recommended with socket E27. The round Globe bulb model fits perfectly either with pendant lights or a table light. The diameter of the bulb should be 95mm with the pendant lights and 125mm with table lamps. The design is compatible with dimmer switches. If you prefer your light dimmable, use a dimmable bulb and a ready installed dimmer switch. All the bulbs are sold separately but can be added to the purchase if you wish. We are always happy to help you with any questions you may have and help you select the right bulbs for your QUU Design light.
