   A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a 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).

   The most commonly used A-series light bulb type is an A60 bulb [7] (or its inch-based equivalent, the A19 bulb [2] [4]), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point [3] and approximately 110 mm (4 + 3 ⁄ 8 in) in length. [8] Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.

   For the rest of this comment I am going to assume an LED is a single P-N junction. Regarding reverse voltage: Most if not all LED manufacturers will list an absolute maximum reverse voltage as 5V. Yet, many people are driving LEDs directly from an AC power line (120V or 240V) with a resistor for current limiting.

   To encourage the shift to LED lamps and other high-efficiency lighting, in 2008 the US Department of Energy created the L Prize competition. The Philips Lighting North America LED bulb won the first competition on August 3, 2011, after successfully completing 18 months of intensive field, lab, and product testing. [94]
