Can You Cut Led Christmas Lights

Calculate the length of the lights you will need.

Can you cut led christmas lights.

You can find led calculators to determine the propper resister but too many different voltages for different leds. If you are handy with a multimeter it is really simple. Wire cutters again a pair can be purchased in any hardware or electrical supply store. 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.

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.

As long as you cut between the dots all of the leds will work. 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. After twisting the wires together secure with a wires connector. 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. R v supply n v led over i led p i led 2 r. Yes you can cut led strings down to whatever length you need. Twist the two bare wire ends together.

Use wire cutters to strip the ends of the two wires cut in the previous step. Each led has a pair of copper dots at the end. As stated you must change the current limiting resister to match. From there you can connect the leds to a power source either through a quick connector or by soldering.

Step 3 cut a portion of one strand of lights to the length you need to add. 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.
