These C7 size retrofit replacement bulbs are commercial grade, faceted LED screw-in replacement bulbs designed for traditional incandescent C7 (E12) sockets. They have a 1-1/2" cone. Each has three super bright LED's encapsulated by a hard-to-break lens (unlike the old-fashioned and very fragile incandescent bulbs). Fits directly into existing traditional sockets without extra transformers. Saves up to 90% on electric use.
