If you’re searching for an efficient lighting solution for your upcoming project, COB LED strip lights deserve your attention. Thanks to their high-density LED chips, COB strips produce a consistent and flawless beam of light, ensuring that your installation achieves a top-notch, polished appearance.
The cutting-edge technology behind COB strips delivers remarkable performance, making them a fantastic option for creating an elegant and professional lighting arrangement. Let’s explore this further.
What is COB LED Strip Light?
COB, which stands for Chip on Board, refers to a technology where LED diodes are directly mounted onto the printed circuit board. A phosphor coating is subsequently applied over these LED chips, acting as an integrated diffuser. The primary benefit of this technology is that it eliminates visible spotting, even in narrow LED profiles or tight spaces, promoting a seamless and uninterrupted installation finish.
This characteristic renders our COB Continuous LED Strip Light perfect for upscale professional and commercial applications. Its superior construction and materials ensure durability and dependable performance over time.
COB VS SMD LED Strip?
COB (Chip on Board) LEDs are integrated directly into the circuit board and covered with a phosphor layer that acts as a diffuser. This design allows for a seamless and uninterrupted light output. Because COB LEDs are mounted directly on the board, there is space for more LEDs, typically achieving between 320 and 528 LEDs per metre.
In contrast, traditional LED strip lights use SMD (Surface Mounted Diode) technology, where the LED chips are mounted on top of the circuit board. This method generally accommodates a maximum of 240 LEDs per metre.
SMD LED strips are more prone to visible spotting and dark patches due to the spacing between the chips. This spotting effect can become more noticeable when the strip is installed in a shallow LED profile with a semi-clear or transparent diffuser.
On the other hand, COB LED strip lights eliminate spotting and can be used effectively without an LED profile, providing a uniform and high-quality light output.
How is COB LED Flexible Strip Manufactured?
The strips are manufactured with the same quality PCB as our other LED Flex Strip lights. Flip chip LEDs are then placed side by side down the center of the strip light, so tight that there are 512 LEDs for every Meter of strip! The strips are finished after a phosphor layer is placed over the LEDs. This helps balance out the color temperature while also acting as a protective layering for the tiny flip chip LEDs underneath.
Advantages of COB LED Flex Strips
No LED Hotspots, even in tight spaces!
One of the biggest complaints about your traditional LED flex strip is the hotspots throughout the strip. A Hotspot is the term for the brighter areas through a fixture or strip where you can clearly see where the light is coming from. Light is much more inviting and attractive when it looks like a smooth source of light, not a spotty mess.
With 5050 SMD Flex Strips the larger sized diodes are packed close enough so that at a distance the light is spread out and consistent on the surface being illuminated, but if the lights are too close to the surface or the strips themselves are visible, the hotspots are an eyesore that cannot be ignored by the human eye.
The strips 528 LEDs/M it would be pretty hard to pick out any hotspots on the COB Flex Strips. The strip illuminates a smooth, consistent light from start to finish. The uniform light has no dark spots and is much more attractive to the human eye, giving off a steady light even in the tightest of places. In fact, the only real way to see hotspots is to look at the back of the strip where it is easier to see the individually placed flip chip LEDs. The only other way you are going to see the individual diodes is if you dim the strips down to about 5% light output. This makes COB Flex Strips ideal for applications where:
- The strip itself cannot be hidden from sight.
- The surface that is being illuminated is within 2 feet of the strip light.
- Reflective surfaces like granite/glass are around.
- Those applications where you want a cool, neon effect.
Brighter Light
That’s right, these COB LED Flex strips are even brighter! At 1400 Lumens/M these are even brighter than our high-density strips! The consistent, bright light also emits at a wider angle thanks to the flip chip LEDs not being encapsulated in a plastic holder like SMD LEDs. This lets them emit some light out the sides so that they spread at 180 degrees off the strip. Wider light angle means more light for you so this is important in the long run for brightness as well!
More Flex
The flexibility of these strips is much better than other flexible strips because of the smaller diode size and even distribution of weight. The diodes are so small and tightly spaced that any point of the strip is the same as the other. The uniformity makes it easy to set up strips without having to plan around a 5050 SMD LED sticking out where you don’t need it. This added flexibility will make them easier to fit into tight areas and turn around corners in your application.
More Efficient, Less Heat
When packing so many LEDs in such a small space, efficiency can come into question. However, flip chip LEDs are superior in efficiency and heat transfer compared to other LEDs. They actually run at 14 Watts / M just like our high-density strip lights but they output 100 Lumens per Watt compared to the 75/W of the high-density strip.
They are also much better at distributing heat as they are mounted directly to the flexible PCB board. This helps them spread their heat down into the PCB rather than keeping it all locked right in the light source itself. This reduction of thermal resistance within the high-density circuit greatly improves the lifetime of the LEDs.

How to Choose the Right COB LED Strip
Selecting the perfect COB LED strip light for your project requires considering several factors. Here’s a comprehensive guide to help you make an informed decision.
Illumination Needs:
Brightness: Determine the desired level of illumination. High chip density (360-480 chips/meter) offers brighter light, ideal for task lighting or under-cabinet applications. Lower density (60-120 chips/meter) is suitable for accent lighting or creating a soft ambiance.
Color Temperature: Choose the color temperature that best suits the application and desired mood:
- Warm White (2700K-3000K) for a cozy atmosphere (residential settings)
- Neutral White (4000K-4500K) for balanced light (kitchens, bathrooms, workspaces)
- Cool White (5000K-6500K) for energizing light (commercial spaces, task lighting)
Installation and Maintenance
Length: Measure the area where the strip will be installed to determine the required length. Consider purchasing extra length for potential cutting and connection.
Flexibility: COB strips are generally more flexible than traditional SMD strips. If navigating tight spaces or curves is necessary, choose a narrower PCB width (2mm-5mm) for better maneuverability.
Power Supply: COB strips typically operate on 12V or 24V DC power.
12V strips are easier to work with for smaller projects due to readily available low-voltage power supplies.
24V strips are better for longer runs or high-power installations to minimize voltage drop over extended distances.
