Key Features of Slim 3mm/5mm Width COB LED Strip Lights

1. Roll-to-Roll Strip with No Joint Points

This COB strip is made in a roll-to-roll process, so the whole roll stays continuous without welding points. That gives the strip a cleaner look and makes it a better fit for projects where you want a smooth light line from start to finish.

2. Narrow Width Options for Tighter Builds

This model comes in 3mm and 5mm width options, so it is easier to fit into narrow channels and slim lighting structures. That makes it a practical choice for sign makers and project installers who need a strip that stays compact.

3. 20mm Cuttable Section for Flexible Layouts

The 20mm cut unit gives you good flexibility when setting up custom layouts. It is easy to adjust the strip for short sections, curved outlines or detailed sign work without wasting extra material.

4. 400LEDs/m for a Soft, Even Glow

With 400 LEDs per meter, the strip gives a soft and balanced light output. It is bright enough for signage and decorative work, but still keeps the glow smooth and comfortable, which helps the final result look neat.
