An LED filament light bulb is an LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light emitting diodes (LEDs). It produces its light by LED filaments, series-connected strings of diodes that resemble the filament of an incandescent light bulb. They are made with the same envelope shapes, with caps to fit the same sockets, and work at the same voltage as incandescent bulbs, and are direct replacements for conventional clear incandescent bulbs. They may be used for their appearance, similar when lit to an incandescent bulb, or for their wide angle of light distribution, typically 300°. They are also more efficient than many other LED lamps.
