A21 LED Bulbs

A-Shape ("Arbitrary") A21 LED light bulbs, or general service bulbs, are likely the light bulb shapes we are all most familiar with. The shape is so ubiquitous that A21 LED light bulbs are likely the first form factor you think of when someone says "light bulb". A21 bulbs are slightly larger than A19 bulbs and typically come in outputs ranging from 75 watts up to 250 Watts in their incandescent forms. Stars and Stripes Lighting offers the largest selection of 75, 100 and 150 watt equivalent A21 LED light bulbs on the market.
