These round mini LED Christmas lights have 50 faceted G12 bulbs. Connect up to 40 strands together. The 25' strands (24' lighted length) have 6" bulb spacing, green wire, and are individually fused to prevent multiple blown strands in the event of a power overload. Individual bulb failure will not cause others to fail. 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 blue, red, green, purple, orange, yellow, warm white, and pure white colors.
