Why there are different PCB width design on LED strips?
When talking about PCB width, as we all known, 3mm, 5mm, 8mm, 10mm, 12mm, 15mm, 30mm are optional. 8mm, 10mm, 12mm are the most common in the market. 3-5MM are super narrow. 15-30MM are super wide.

8mm, 10mm, 12mm are the most common in the market. 3-5MM are super narrow. 15-30MM are super wide.
What are the core differences of their applications;
- Narrow PCB (3mm, 5mm): The advantage of these COB strips lies in their extreme slim in size. Commonly used in car ambient decoration
- Common PCB (8mm, 10mm, 12mm): These are the most mainstream and common sizes available on the market.
- Wide PCB (15mm, 30mm): A wider PCB allows for more and higher-power LED chips, resulting in extremely high brightness output.
