This clear 100-light, 22-foot-long set of mini Christmas lights on green wire is ideal for densely lit holiday lighting projects because its 2.5 volt, 3000-hour bulbs are spaced every 2.5" (much closer together than the standard 6" spacing), which is great for projects that may need a higher concentration of bulbs on shorter wire. Go ahead -- decorate your wreaths and bushes, wrap your trees, and enjoy a beautiful illumination. Featuring snap-lock sockets that prevent twisting and pulling of the lamps, these bulbs will remain securely in place to eliminate vandalism and light loss. If one bulb goes out the rest stay lit. Every set includes 2 replacement bulbs, 1 flasher bulb, and fuses. Safe for indoor and outdoor use. UL Listed for indoor/outdoor use. Power usage is 40.8 Watts (0.34 Amps) Per Set.
