Christmas lights have never been so bright and vibrant. These C7 size retrofit replacement bulbs are warm white. They are specially made to be dimmable. They are commercial grade, frosted, LED screw-in replacement bulbs designed for traditional incandescent C7 (E12 socket) sockets. They have a 1-1/2" cone. Each has one super bright LED's encapsulated by a hard-to-break lens (unlike the old-fashioned and very fragile incandescent bulbs). Each bulb consumes .58 watt of power on one 15 amp circuit. Fits directly into existing traditional sockets without extra transformers. Saves up to 90% on electric use. Recommended for computer animated displays requiring dimming. Sold in packs of 25 bulbs.
