Lux360 D5 LED icicle lights line rooflines, eaves and railings with even, vibrant light that looks good from every angle. Traditional LED Christmas lights shine from a single point inside the bulb, which creates hot spots, dead spots and uneven color. The proprietary D5 lens works differently: it pairs a higher-output LED chip with a lens that diffuses the light across the entire bulb surface, so each light glows with soft, rich color whether you see it from the street, the sidewalk or the front porch. Each set has 70 lights on 15 icicle drops along 7 feet of white wire. The drops repeat in 18-, 15- and 9-inch lengths, spaced 6 inches apart, with 3 inches between lights, and the white wire blends with white gutters and trim. Connect more sets end to end to run the length of a roofline; the fused, stackable male plug lets you plug other lights in at the outlet. Sealed, one-piece bulbs with shatterproof acrylic lenses keep water out, and the bulbs are rated for up to 100,000 hours. If one bulb goes out, the rest stay lit.
