LED strip lights are popular for both residential and commercial use, offering flexible, energy-efficient lighting. Two main types—COB (Chip on Board) and SMD (Surface Mount Device)—differ in design, performance, and ideal applications.
Common Features
- Technology: Both use flexible PCBs and low-voltage power (12V/24V DC).
- Applications: Suitable for indoor/outdoor decor, accent lighting, and signage.
- Efficiency: Long lifespan (30,000–50,000 hours) and low heat emission.
Key Differences
| Feature | COB Strip Lights | SMD Strip Lights |
|---|---|---|
| Design | Dense, seamless LED chips for smooth, dot-free light | Spaced individual LEDs (2835, 5050, etc.) |
| Light Quality | Uniform, glare-free illumination | Brighter per LED, but may show dark spots |
| Durability | Robust, but damage may affect larger areas | Easier to repair individual LEDs |
| Cost | Higher due to advanced design | More affordable and widely available |
| Installation | No diffuser needed in most cases | May require diffusers for smooth output |

Best Use Cases
- COB: Ambient lighting, display shelves, vanity mirrors—anywhere uniform, dot-free light is preferred.
- SMD: RGB effects, under-cabinet lighting, outdoor signage, pixel-controlled displays.
Conclusion
COB strips offer a premium, seamless lighting effect ideal for elegant spaces, while SMD strips provide brightness, flexibility, and affordability for dynamic or high-performance projects. The right choice depends on your needs for visual quality, control, and budget.
