With the advent of technology, LED strip lights have become popular. However, LED lights have diverse types and applications, like COB and SMD. Knowing the characteristics of each LED type is important to making the right choice. Here is an expert-written blog providing a detailed comparison between COB VS SMD LED strip lights.
What Is a COB LED Strip?
Let’s start the blog by understanding the COB LED strip. COB stands for “chip on board” and is a special on-board technology. Here, tons of small LED chips are closely packed with one another. Later, this principal chip is mounted on a board. It provides the LED strip with smooth-looking light with no visible dots. The best part of this technology is that it allows for a higher density of LED chips. Thus, it offers an innovative edge over conventional technologies.
What Is an SMD LED Strip?
Now comes SMD LED strips. SMD stands for “surface-mount device.” Engineers directly solder LED lights onto printed circuit boards (PCBs). The process makes the LED strip smaller and easier to use. Thus, unlike traditional LED packages, the entire strip is compact yet versatile.
COB VS SMD LED Strip: A Comprehensive Comparison
If you compare SMD LEDs in the market to COB LEDs, it was the 1960s when SMD LEDs gained fame. However, till 1986, these LEDs accounted for just 10% of the market. Later on, with advancements in LED technology, the SMD LED strips earned a significant market share. In contrast, COB LEDs first gained popularity in the 2000s. At that time, COB was more expensive to produce than SMD LED Strip Lights. However, at present, even COB manufacturing has streamlined. Here is a quick comparison between the two LED lights based on different features:
Brightness
Let’s start with brightness and light quality. COB LEDs have higher brightness and feature efficient heat dissipation. In contrast, SMD LEDs’ brightness levels depend on strip types. For example, SMD 5050 is brighter than SMD 3528, and so on.
Light Quality
SMD LED strips feature visible light dots that create non-uniform illumination. COB LED strip lights eliminate visible hotspots with uniform light, making them perfect for tasks requiring minimal shadows.
Efficiency
Regarding energy efficiency, COB LED strip lights are far better than SMD LED Strip Lights. However, SMD LED strips use more energy. SMDs can generate more heat, which demands better heat management. COBs have effective heat dissipation, allowing higher performance and longer lifespan.
Design
If you are looking for a slim and flexible design, you should go for COB LEDs. COB LED strips have a seamless aesthetic design that makes them perfect for tight and intricate spaces. In contrast, SMD LEDs are slightly bulkier but still suitable for visible LED points.
Durability and Longevity
Outdoor LED strips must be sturdy enough to withstand weather extremes. COB LED strip lights are strong enough to protect them from dust and physical damage. SMD LEDs, on the other hand, have individual diodes that make them prone to damage and failure. COB LEDs last longer than SMD LED strip lights.
Budget
The last factor that plays an important role in making a decision is cost. COB LEDs feature advanced technology and superior performance, which makes them expensive. In contrast, SMD LEDs are affordable and thus perfect for conscious projects. However, with little knowledge and bargaining skills, you can find a cost that fits your budget.
Here is a quick table to help you understand better between LED COB VS LED SMD:
| COB LED VS SMD LED | ||
| Feature | COB LED Strips | SMD LED Strips |
| Brightness | Higher lumens per watt | Variable depends on the model |
| Light Quality | Uniform, no hotspots | Visible individual LEDs |
| Energy Efficiency | More efficient | Slightly less efficient |
| Heat Management | Better heat dissipation | Moderate, varies by design |
| Design Flexibility | Slim and seamless | Bulky with visible LEDs |
| Cost | Higher | Lower |
| Best Applications | Task, architectural, décor | Accent, ambient, DIY |
Advantages and Disadvantages of SMD LED Strips
Let’s quickly summarize the advantages and limitations of SMD LED strips. This information can help you make an informed decision.

Applications of SMD and COB LED Strips
Every article related to LED COB VS SMD is incomplete without understanding the applications of both lighting systems. Both SMD and COB LED strips are versatile and suit specific applications. Knowing the applications will give you the power to make the right decision. Here are the applications of both LED strips:
Applications of SMD (Surface Mounted Diode) Lights
With their cost effectiveness and wide range of configurations, SMD lights are used as:
- Accent Lighting: To highlight architectural features, artwork, or furniture.
- Ambient Lighting: To set mood lighting in homes, offices, and commercial spaces.
- Task lighting: As an under-cabinet lighting, study desks, or workbenches.
- DIY Projects: For custom or hobby projects like small electronics, 3D printers, etc.
- Outdoor Lighting: For illuminating pathways, gardens, and outdoor decorations.
