01 What Are COB LED Strip Lights?
COB stands for chip on board. Instead of a few bright dots, COB strips mount a dense, continuous row of tiny LED chips and cover them with a phosphor coating — so the whole strip glows as one smooth, dot-free line of light.
That is why COB strips look like a solid neon tube rather than a row of point lights. They are the go-to choice wherever the strip itself will be seen up close.
Curious how they compare? Read our COB vs SMD LED strip guide.
02 How Do COB LED Strip Lights Work?
A COB strip lays its LED chips in a single dense line along the PCB, then seals them under one continuous phosphor layer. The coating spreads the light and removes the dark gaps you see on standard strips, giving an even glow from edge to edge.
Because the chips run close together, COB strips reach high luminance per meter while staying flexible, cuttable and easy to install — just peel, press and connect to a 12V/24V supply.

03 How to Cut & Solder COB LED Strip Lights?
To make your own COB LED strip light, you cut the tape to length and then solder the wires. Here are some tips on how to do it:
1
Cut at Marked Points
Find the copper pads printed on the strip and cut exactly along the marked line — never through the LED chips.
2
Solder the Wires
Tin the copper pads, then solder your positive and negative wires onto them in a few seconds to avoid overheating.
3
Protect the Joint
Cover the soldered area with silicone or heat-shrink tubing so the connection stays clean and moisture-proof.
4
Test Before Installing
Connect to the power supply and check the full run lights up evenly before you mount it.
Prefer a plug-and-play install? Quick connectors are available as an alternative to soldering.

06 Frequently Asked Questions
Quick answers to the questions our customers ask most. Browse our LED lighting guides for more buying tips.
Q1What does COB mean in LED strip lights?
COB stands for chip on board — a strip that mounts a dense row of chips under one continuous coating for a dot-free glow.
- Dense LED chips laid out in a single continuous line
- One phosphor coating spreads the light evenly
- No visible dots — looks like a solid neon line
- Available in white, tunable white and color versions
Q2What is the difference between COB and SMD LED strips?
SMD strips show visible dots; COB strips emit a smooth, continuous line of light.
- SMD: separate point-light LEDs with visible gaps
- COB: continuous, dot-free line with even brightness
- COB typically offers higher CRI and better uniformity
- Both are flexible, cuttable and easy to install
Q3Can COB LED strips be cut and bent?
Yes — COB strips cut at marked lines and flex around curves like standard strips.
- Cut at the marked lines every few centimeters
- Reconnect with solder or quick connectors
- Flexible enough for corners and curved surfaces
- Waterproof IP65/IP68 versions suit outdoor use
