COB vs. SMD LEDs
An interactive guide to understanding the two dominant LED technologies. Discover the core differences in performance and design to choose the perfect lighting for your needs.
Light Quality: The Most Striking Difference
The most immediate way to tell COB and SMD LEDs apart is by the appearance of their light. Hover over the strips below to see the "dotless" glow of COB versus the "polka dot" effect of SMD.
COB (Chip on Board)
A single, continuous and uniform light source. Ideal for a seamless, high-end look.
SMD (Surface Mounted Device)
A series of distinct points of light. Often requires a diffuser for a smooth appearance.
A Deeper Dive: Performance Metrics
Beyond appearances, COB and SMD differ significantly in key performance areas. Select a metric below to compare them side-by-side and see how their underlying architecture impacts performance.
Energy Efficiency
COB's high-density chip design allows it to produce more light per watt, making it significantly more energy-efficient. This leads to brighter light output and long-term energy savings, justifying its higher initial cost.
Choosing the Right Technology
The best choice depends entirely on your project's needs. This section provides clear recommendations based on the strengths of each technology, helping you make an informed decision.
Choose COB LEDs when...
- ✨ A "Dotless" Look is Crucial: For under-cabinet, cove, or any visible linear lighting where a smooth, uniform glow is desired.
- 💡 High Brightness is a Priority: For high-bay fixtures, spotlights, and street lamps that require maximum lumen output from a compact source.
- 🌍 Energy Efficiency Matters: For applications where long-term energy savings and lower operational costs are key factors.
Choose SMD LEDs when...
- 🎨 You Need Color-Changing (RGB): SMD is the only option for dynamic, multi-color lighting effects in decorative and accent applications.
- 🎯 Focused Light is Required: For task lighting or directional spotlights where a narrower, more concentrated beam is needed.
- 💲 Budget is a Primary Concern: SMD offers a more cost-effective solution for general-purpose LED lighting without a large upfront investment.
