COB (Chip On Board) LED and SMD (Surface Mounted Device) LED are two popular technologies used in LED lighting, including Unilite work lights. Both offer advantages in terms of energy efficiency, durability, and lifespan, but there are some key differences to consider when reviewing the Unilite lineup. We utilize both LED technology in our flashlights, site lights, inspection lights, lanterns and headlamps.
Getian are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
One of the main differences between COB and SMD LEDs is their size and design. COB LEDs are larger and consist of multiple LED chips that are mounted directly onto a substrate. This allows for a higher density of light output and a more efficient use of space. In contrast, SMD LEDs are smaller and consist of a single LED chip that is mounted onto a printed circuit board (PCB). This results in a lower density of light output but allows for more flexibility in design and placement. In our best-seller, the IL-925R Folding Inspection Light features COB LED for the two primary lights and an SMD LED for the top torch, making it perfect for plumbers, electricians and carpenters.
Another key difference between COB and SMD LEDs is their beam angle and light output. COB LEDs tend to have a wider beam angle, which means they can provide more uniform and diffuse lighting over a larger area. This makes them ideal for applications where a wide and even spread of light is desired, such as in a workshop, job site, or garage. Our all-new RF- and RF- Flood Lights utilize COB LEDs for this reason. If you&#;re working in the trades industry and need good site lighting, you can&#;t go wrong with these. SMD LEDs, on the other hand, have a narrower beam angle and are more directional, making them better suited for task lighting or spotlighting specific areas. Our popular PL-3 Aluminum Inspection Light is a great example of this and often used by emergency personnel, service techs and mechanics.
In terms of energy efficiency, both COB and SMD LEDs are highly efficient and can last a lot longer compared to traditional LED technology. However, COB LEDs tend to be slightly more efficient due to their higher density of light output and the fact that they use fewer components. This can translate into a longer lifespan for the LED. We utilize a white COB LED at k in our impressive SLR- Compact Work Light.
Durability is another important consideration when choosing a work light, and both COB and SMD LEDs are known for their long lifespan and resistance to damage. COB LEDs, however, tend to be more durable due to their larger size and the fact that they have fewer components, which makes them less prone to failure. Rest assured, all our work lights are built tough and have been put through the ultimate tests prior to launch.
Overall, both COB and SMD LEDs are great for work lights and we put a lot of thought and engineering to ensure we use the right type of LED, for every light we manufacture. If you need a wide and even spread of light over a large area, COB LED technology may be the better choice. If you need more directional and focused lighting for specific tasks, SMD LEDs may be the way to go. Both technologies offer efficiency, durability, and long lifespan &#; something we strive for here at Unilite.

LED lights come in a variety of types. Among them COB and SMD LED gain great popularity. And here comes the question, SMD VS COB LED, what are the differences?
Key difference in SMD and COB LED components
*SMD LED construction
SMD LED, which is short for Surface Mounted Device LED, is the most common LED in the market. The LED chip is a versatile electronic component that is permanently fused to a printed circuit board. It is applied to light bulbs and string lights, as well as your 's notification light.
SMD LED chips are available in a variety of sizes. For example, one of the SMD chips, the SMD LED is 5mm wide while the SMD has a width of 3.5mm. As you can see, SMD chips are compact, practically identical to the flat, square computer chip architecture.
*COB LED construction
What is LED COB? COB LED technology is a recent advancement in LED lighting that allows for more effective energy use. As for COB manufacturing, it has several diodes on the same surface as SMD chip does. However, the distinction between them is that COB LED has more diodes.
Typically, COB chips feature 9 or more diodes. No matter how many diodes, they have only one circuit and two contacts, resulting in a panel-like look of COB LED lights.
Other differences in characteristics
1. Brightness
When SMD VS COB LED in brightness, it also distinguishes. The level of brightness highly depends on the lumen output by the involved chips. Generally speaking, compared to other light sources, LED lights are capable of illuminating with brighter light, a result of higher lumen. But among different types of LED, the lumen differs.
For example, COB LED lumen is 80 lumen per watt at least, while SMD applies 50 to 100 lumen per watt, while the lowest measure of COB is 80 lumen per watt. Therefore, lights with COB are brighter.
2. Energy efficiency
In general, working with LED light like COB light ensures great energy efficiency. This is why, in comparison to filament bulbs, they are gaining popularity and becoming the most favored light source.
With this in mind, you can assured that both SMD and COB LEDs will be extremely energy efficient. But pay attention that the energy efficiency varies according to the lumens used. The higher the lumen measures, the greater the energy efficiency is.
3. Color temperature
SMD is more adaptable and offers a wider range of options when it comes to color and color temperature. It is easier to get a varied color since different primary colors can be used. When you wish to adjust the color temperature, it also works. A red, green, or blue diode could be included in the chip. You can already make practically any color with these three diodes by altering the output level.
As for the COB, however, the ability to modify the colors and color temperature is limited. It is designed to emit only one color and temperature of light. But as a result, it offers more stable lighting.
4. Quality of light
When it comes to the quality of light, it is also different when SMD VS COB LED. This is primarily due to the fact that they each use different numbers of diodes, which influences the brightness and range of lighting.
When it comes to SMD LED lights, the resulting light has a glare to it and is ideal to be utilized as a point light, a result of the attachment of multiple light sources.
COB light fixture, on the other hand, will emit a uniform and glare-free light. It produces a light beam that is homogeneous and easy to modify. This is primarily because of its wide-angle beam, which makes it a better light source. Therefore, you can DIY LED COB as surface light.

5. Cost
The cost of getting devices built with these different technologies differs. They are both strongly dependent on manufacturing costs, which are distinct.
When compared to its counterpart, SMD has a greater production cost. For example, SMD is more expensive than COB when comparing the labor and manufacturing process to the material cost.
Generally, the cost of SMD accounts for 15% of the total material cost. As for COB, labor and production costs contribute for 10% of the material cost for. This demonstrates that chip on board LED saves you roughly 5% on manufacturing costs.

LED lights play an important part in our daily life, especially in photography and architectural lighting. When having a purchase, SMD VS COB LED, which is more suitable? Let&#;s have a look.
Photography
In most cases, LED COB bulbs are wildly used in LED video light for photography. As we know, COB lights features luminous uniformity because of its wide beam angle, making it preferable among photographers and filmmakers.
For example, the COLBOR CL100 is a 100W COB LED light. It provides stable 100W output in bi-color temperature, enabling you to spend less time adjusting the setting. Moreover, it is incredibly light so that you can use it for mobile filming without burden. The CL100 helps you show objects in natural colors.
Architecture
In architectural lighting, COB LED chips are utilized in more complex lighting applications to provide better beam angles and more aesthetically pleasing fixtures. However, SMD LED are utilized in more general lighting fixtures like diffused panel lights, which have a frosted diffuser covering the light source.
Conclusion
The differences in SMD VS COB LED are various such as brightness, color temperature, manufacture cost. Meanwhile, they are suitable for different applications. Just have an understanding of them and you will get an ideal LED light for video shooting and other uses.
