Can You Cut Led Christmas Lights

No you can t lengthen or shorten standard series wired incandescent and led christmas tree light strings that are made with 2 or 3 wire harnesses.

Can you cut led christmas lights. Each led has a pair of copper dots at the end. Yes you can cut led strings down to whatever length you need. Electrical tape this is optional but if you want to make sure that your wire nuts are secured then it s best to purchase a roll as well. If you are handy with a multimeter it is really simple.

When your three strand christmas lights are too long for the place you had intended and you do not have any shorter strands you can shorten your light strand in a couple of easy but time consuming ways. After twisting the wires together secure with a wires connector. This problem can occur when christmas lights are added to the yard and yard decorations. You can find led calculators to determine the propper resister but too many different voltages for different leds.

For instance if the christmas lights stretch to 25 feet and you need to cover 35 feet you will need two 25 foot light strands. Twist the two bare wire ends together. As long as you cut between the dots all of the leds will work. Unless you are only shortening the strand by five or less individual lights should not be removed because the remaining lights will receive too much power and burn out much faster.

Even if they work at first they won t last long. If however you are installing c7 c9 18 awg christmas light cords with sockets and screw in bulbs that are wired in parallel yes you can shorten them. They re also available online. With the lights unplugged cut the two wires that enter the last light in the series strand with wire cutters.

Led strip lights are designed to be easy to cut apart with a pair of scissors. From there you can connect the leds to a power source either through a quick connector or by soldering. As stated you must change the current limiting resister to match. If you know or can measure the led current for each led end therefore for a series and the voltage drop of each and the applied voltage you could calculate the resistance and wattage of a resistor to limit the current to a safe value.

They will be used to cut and shorten your led christmas lights. Wire cutters again a pair can be purchased in any hardware or electrical supply store. We explained in our article answering the question are christmas lights in series or parallel we discussed that while mini lights with small wiring harnesses wired in series cannot be easily cut to custom lengths parallel wired cords can be cut and terminated.
