How to Cut LED Strip Lights
LED strip lights have become increasingly popular over the last several years. They provide easy-to-install decorative lighting while being energy efficient. Before starting any project involving LED strip lights, it is important to know how to customize the length correctly. Follow the guide below on how to cut your strip light correctly and safely.
Materials needed:
- LED Strip Lights
- Tape measure
- Scissors
Important note: Before you begin, be sure your LED strip is not plugged into any type of power source.
Step 1: Measure the Area
Measure the area where you plan to install your strip lights to ensure you have the right length.
Step 2: Locate Copper Pads
Once the length has been determined, locate the nearest copper pad on the LED strip light.
Step 3: Cut Down the Center
Finally, use scissors to cut down the center of the copper pads.
Common Mistakes to Avoid
When cutting your LED strip lights, there are a few common mistakes you would want to avoid. Some of these mistakes include:
- Cutting the LED strip in the wrong place
- Using the wrong tools
- Not sealing the end of the strip properly
When cutting an LED strip light, make a straight cut along the marked line in the middle of the copper pads, which can be indicated with a solid line, dotted line, or an image of scissors. When making this cut, use the proper tools, such as scissors or a utility knife. Using dull tools can crush the strip or cause uneven cuts, which would cause improper functionality. If you use any type of weatherproof or waterproof strip light, properly seal the cut edge with waterproof sealant and silicone end caps. This ensures that the LED strip remains resistant to water and can withstand the wet conditions of the environment.
Reconnecting Cut LED Strip Lights
After you have cut your LED strip lights, you might find yourself in a situation where you need to connect the cut segment to a controller, power supply, or other strip light. They don't have to be identical in length, but they should be the same strip type (for ex, single CCT, RGB, RGBW, etc.), preferably the same strip to keep it simple for this purpose. They have to at least be the same voltage. Most often, strips would be cut, and then the wire would be added between the two cut sections to cover a gap between sections. Like between sections of cabinets for undercabinet lighting.
It will work properly if the power supply runs at most 80% of its capacity. If a power supply operates at more than 75-80% of its capacity, its life span will decrease. For example, a power supply could run at 15% or 20% of its capacity.
Cut segments can be reconnected at the copper pads, or a power wire can be added to the new strip. This can be done by soldering or by using our solderless connectors. Both options are effective and easy to accomplish. You are ready to continue your project once you have reconnected your LED strip segments.
