These C9 LED string light strands come with 25 retro faceted bulbs. Connect up to 85 strands together, and hang them using the built-in clip on each bulb. The 17' strands (16' lighted length) have 8" bulb spacing, green wire, and are individually fused to prevent multiple blown strands in the event of a power overload. These LED string lights consume 90% less energy than traditional incandescent strands and last 25 times longer. Each shatterproof bulb is made into the strand (not removable), which eliminates the chance of corrosion. Use these string lights indoors or out for anything from Christmas, Halloween, and Valentine's Day to party and patio lighting. Strands are available in red, yellow, orange, blue, purple, green, warm white, and cool white colors.All specifications are subject to change without notice.
