This is a set of warm white, 12-volt DC Christmas lights on green wire. The set is made in two parts. A section of lights and a separate 15-foot cord extension wire that has an accessory plug on one end and a coaxial connector on the other. Here are the specifications.
The light section has 20 warm white LED bulbs spaced 6 inches apart. That's 9.5 feet of lit length and has male and female coaxial end plugs. Warm white is a modern LED interpretation of the warm yellow glow of glass, incandescent Christmas light strings. While not an exact match, they are neutral to warm and will blend with traditional lights, if they are mixed in your project.
They do not mix well with pure white LED sets. Note that the LED light sets, these little lights, are designed as a single unit to resist corrosion and cannot be removed or replaced. If one bulb should go out, the others will stay lit.
The wiring is a hefty 22 gauge, and up to 30 of the light sections can be connected end to end and connected to a single adapter cord.
These lights are rated for indoor and outdoor use. Thank you for shopping at Christmas Light Source, and Merry Christmas.
