When determining whether COB lights are superior to conventional LED lights, it is essential to consider the specific requirements of each application. COB (Chip on Board) LEDs provide powerful, concentrated illumination alongside a sleek aesthetic, yet they are generally associated with higher costs and slightly reduced heat dissipation compared to standard LED lighting.
In contrast, traditional LEDs are known for their adaptability and cost-effectiveness, making them suitable for most general lighting applications. Each type has its own advantages, making them complementary components within the ever-evolving COB LED Market.
When selecting the optimal lighting solution, assess the unique requirements of your environment and the features you prioritize in lighting technologies.
LED technology encompasses various types, with COB and SMD (Surface Mounted Device) LEDs being among the most popular. This brings us to the critical question: What separates SMD LED from COB LED?
Essential Variations in SMD and COB LED Design
Construction of SMD LEDs: The SMD LED is the most widely used form of LED today, where its electronic component is permanently attached to a printed circuit board. These LED chips can be found in various applications, including light bulbs and decorative string lights.
SMD LED chips come in numerous sizes; for instance, one common version measures 5mm, while another variant is only 3.5mm wide, demonstrating their compact nature that resembles flat, square computer chips.
Construction of COB LEDs: COB technology represents a significant development in LED lighting, improving energy efficiency by housing multiple diodes on the same surface. Unlike SMD LEDs, COBs typically feature nine or more diodes, consolidated into one circuit with two contacts, resulting in a panel-like appearance.

Additional Characteristic Differences to Consider
1. Brightness Levels
When pitting SMD against COB in brightness, the distinction becomes evident. Brightness is measured in lumens, and generally, COB LEDs produce a minimum of 80 lumens per watt, whereas SMD chips range from 50 to 100 lumens per watt. Hence, COB lights are typically brighter.
2. Energy Efficiency
Both types of LEDs offer significant energy efficiency, especially when compared to traditional filament bulbs, which is why they have become a preferred choice. However, energy efficiency may vary based on lumen output — the higher the lumen count, the better the energy utilization.
3. Color Temperature
SMD LEDs are more flexible with a broader palette of color temperature options, allowing you to modify the color with different primary diodes. In contrast, COB LEDs emit a singular color and temperature, providing stability but less versatility.
4. Light Quality
Light quality differs between both SMD and COB. SMD lights can generate glare, making them better suited for focused point lighting, whereas COB fixtures provide a uniform, glare-free illumination with a wider beam angle, rendering them ideal for general lighting use.
5. Cost Considerations
The manufacturing costs for SMD and COB devices differ significantly. Typically, SMD lights incur higher production costs, contributing to overall expenses. In fact, SMD production costs account for 15% of material costs while COB accounts for only 10%, leading to a savings of around 5% in manufacturing for COB technology.

Application Suitability Based on Differences
LED lights play a vital role in day-to-day life, especially within photography and architectural applications. When evaluating SMD vs. COB LEDs, which is more fitting? Let’s explore.
Photography Applications
COB LED bulbs are extensively utilized in LED video lighting setups due to their ability to offer uniform luminosity, a characteristic highly valued by photographers. An illustration of this is the COLBOR CL100, a 100W COB LED light that provides stable power output with adjustable bi-color temperature, enhancing efficiency and ease for mobile filming.
Architectural Lighting Usage
COB LEDs are preferred for complex architectural lighting systems, providing better beam angles and aesthetically pleasing designs. Conversely, SMD LEDs are used in standard lighting fixtures like diffused panels that feature frosted coverings.
Final Thoughts
The comparison between SMD and COB LEDs highlights diverse aspects such as brightness, color temperature, and manufacturing costs, reinforcing their suitability for different applications. A proper understanding of these differences can guide you to select the ideal LED solution for your specific needs.
