COB LED vs SMD LED Comparison
Chip packaging comparison.
SMD spreads many small emitters across a board and is the workhorse of general lighting. COB packs the emitters into one dense array, which removes the dot pattern and concentrates output — at a higher cost per lumen.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Light appearance | Uniform dot-free | Visible dots | Application-dependent |
| Efficiency | High | Very high | SMD LED |
| Cost per lumen | Higher | Lower | SMD LED |
| Best for | Display, strip | General lighting | Application-dependent |
Conclusion
Choose SMD for cost-sensitive general lighting and higher efficacy. Choose COB where the light source is visible or must be uniform — display, hospitality and linear accent — and accept the price premium.
