LED Strip Cutting Points - Where to Cut? Detailed Guide

Cutting LED strip lights at the correct point is crucial for both safety and performance. An LED strip cut at the wrong point can be damaged or short-circuited.

Why Should LED Strips Be Cut at Specific Points?

LED strips include cutting points at specific intervals. If cut outside these points:

• ❌ LEDs may be damaged
• ❌ A short circuit may occur
• ❌ Warranty may be voided
• ❌ The incorrectly cut section will not work

How to Find the Cutting Point?

LED Strip Type	Cutting Interval	Cutting Mark
30 LED/m	Every 10 cm	Scissor symbol
60 LED/m	Every 5 cm	Copper pads
120 LED/m (COB)	Every 2.5 cm	Copper line
RGB strip	Every 5-10 cm	Scissors + 4 pads

Step-by-Step Cutting Process

1. Unplug the LED strip from power
2. Identify the cutting point (scissor mark or copper pad)
3. Cut straight with sharp scissors
4. Connect a connector or solder to the cut end
5. Test

LED Strip Length Limits

Voltage	Max. Length (from Single Feed)	For Longer Lengths
12V	5 meters	Connect power supply in the middle
24V	10 meters	Make a parallel connection

❓ Frequently Asked Questions

What happens if an LED strip is cut in the wrong place?

The cut LEDs may be damaged, and that section will not work. It must be cut through the center of the copper pads.

Can a cut LED strip be reconnected?

Yes, it can be reconnected with a connector or by soldering. Connectors are easier, soldering provides a more secure connection.

How many meters of LED strip should not be connected?

For 12V strips, a maximum of 5 meters from a single feed. For longer distances, connect the transformer in the middle or use a 24V strip.

Is RGB LED strip cutting different?

The same principle applies, but there are 4 copper pads (R, G, B, +). All 4 pads should be visible at the cutting point.

What should be attached to the end after cutting?

A connector (easy installation) or solder (more secure). Prefer soldering in humid areas.
