The ToLEDo LED GLS filament range from Sylvania is designed to bridge the gap between LED technology\'s modern functionality and the traditional light bulb aesthetic. Features a ES-E27 Edison screw (27mm) base/cap. Also known as an A60 light bulb.Each light bulb in the range consumes minimal power but producing light of equivalent quality and brightness to traditional filament light bulbs. Designed to directly replace incandescent filament light bulbs and retrofit seamlessly to existing installations, this light bulb is absolutely identical in terms of its appearance.Four tensile LED filaments elegantly mimic those of a traditional light bulb and produce a similar warm white light, but where the older filament version would use 35W, this LED Crown Silver GLS only uses 4.5W. Add to this an LEDs superior longevity and the reduced frequency with which it needs replacing, then the cumulative savings associated with this LED light bulb have endless potential.This GLS is a newer product from Sylvania and supercedes their old GLS part codes: 27157.Need more help in choosing a suitable light bulb?
