Christmas lights have never been so bright and vibrant. These C9 size retrofit replacement bulbs are green 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). Fits directly into existing traditional sockets without extra transformers. Saves up to 90% on electric use. These are not your average 120V they are 240V. Sold in packs of 25 bulbs.
