E12 4W LED Spherical Filament Bulb
Transforms your surroundings
Designed for everyday living
Quality that endures

This E12 4W LED Spherical Filament Bulb from Solae Design is a replacement lamp for fixtures bought from us, built around an 18K gold wire LED filament in a clear glass envelope on an aluminium body. At 4W it draws a fraction of the power of an incandescent equivalent while producing the same warm, familiar filament glow that suits an exposed-bulb fixture.
Two envelope sizes are offered. The smaller measures 0.9 inches across and 2.1 inches tall, suited to compact candelabra fittings and chandeliers where the lamp sits in plain view. The larger measures 1.6 inches across and 2.4 inches tall for fixtures with more room in the shade. Both take a standard E12 socket and come in silver or clear finishes.
Please note this bulb is stocked specifically as a replacement part for Solae Design fixtures, and we do not fulfil standalone orders from customers who bought their fixture elsewhere. If you need a general-purpose E12 lamp, a standard bulb from a major retailer will ship faster and offer broader compatibility for everyday use around the home. The aluminium body helps shed heat and the glass envelope is clear, so the filament stays visible and the lamp suits any fixture where the bulb is on show rather than hidden inside a shade.
