COB vs. CSP - How different are they?

When selecting LED strips for your lighting needs, two innovative options often stand out: COB (Chip On Board) and CSP (Chip Scale Package). Both of these technologies offer unique benefits and cater to different applications, making them versatile choices for a variety of lighting projects.

COB LED Strips (Chip On Board)

COB LED strips feature a high-density array of tiny LED chips mounted directly on the strip, creating a seamless and uniform line of light. This makes them ideal for applications requiring consistent, soft lighting, such as under-cabinet or accent lighting. COB strips also offer excellent color accuracy (high CRI) and are highly energy-efficient, providing bright light with lower power consumption.

CSP LED Strips (Chip Scale Package)

CSP LED strips offer a more compact and advanced design by eliminating traditional components, resulting in a slimmer and more flexible profile. They are known for their “dotless” illumination, providing a smooth, even beam without visible dots—perfect for sleek, modern lighting in architectural and decorative applications. CSP strips are highly reliable and provide excellent heat dissipation for long-lasting performance.

Key Differences

Both COB and CSP LED strips provide high-quality lighting but differ in design and effects. COB strips deliver a continuous, bright light with great color rendering, while CSP strips offer a minimalist, dotless light for modern aesthetics.
