We recommend using LED bulbs as they are energy efficient and do not generate high heat levels. You may like to experiment with the strength of the bulbs to achieve your desired brightness / ambience in the space.
You can also use pearl or clear bulbs to create different effects - a pearl bulb will contain the light within the pendant to create a warm glow whereas a clear bulb will punch the light out through the weave to create a patterned effect on surrounding ceiling and close walls.
Choosing between a warm or cool white bulb will also effect the ambience you create - we typically use a warm white bulb.
