Decorate this Christmas season with these T-50 size retrofit replacement bulbs. They are frosted LED screw-in replacement bulbs designed for traditional incandescent T50 (E26 socket) sockets. Each has ten super bright LED's encapsulated by a hard-to-break lens (unlike the old-fashioned and very fragile glass incandescent bulbs). Fits directly into existing traditional sockets without extra transformers. Saves up to 90% on electric use with 1.5 watt per bulb.
