Christmas lights have never been so bright and vibrant. These C9 size retrofit replacement bulbs are gold in color. They are commercial grade, faceted, LED, screw-in replacement bulbs designed for traditional incandescent C9(E17) sockets. They have a 1-1/2" cone shape. Each has 5 super bright LEDs encapsulated by a hard-to-break lens (unlike the old-fashioned and very fragile incandescent bulbs). Each bulb consumes .45 watt of power on one 15 amp circuit. Fits directly into existing traditional sockets without extra transformers. Saves up to 90% on electric use. Sold in packs of 25 bulbs.
