What is Constant Current COB LED Strip ?
Constant Current COB LED Strip integrates a built-in constant current IC, ensuring each chip receives a stable and consistent current. This design guarantees uniform brightness across all LED chips, eliminating issues such as uneven lighting or premature light decay caused by current fluctuations.
Unlike traditional COB LED strips, which often use resistor-based voltage reduction and are highly affected by input voltage variations (leading to overheating or unstable currents), the constant current design addresses these challenges effectively. It ensures reliable performance, longer lifespan, and improved lighting quality.

Custom LED Strip Supplier & Manufacturer
LEDWorker is a leading manufacturer and supplier of high-quality LED strip lights, specializing in customized solutions for residential, commercial, and industrial applications. Our automated production lines ensure product consistency and quality, enabling us to provide reliable, energy-efficient lighting solutions. We offer extensive OEM and ODM services, tailoring LED strips to meet specific requirements such as LED density, PCB width, color temperature, and waterproofing level.
Our commitment to quality is underscored by certifications, including CE and RoHS, ensuring safety and environmental friendliness. With competitive pricing, flexible order quantities, and a dedicated support team, LEDWorker is a trusted partner for all LED strip lighting needs.
Customizing LED Strip Components:
1. Customizing LED Quantity:
Based on customer requirements, the number of LEDs per meter can be adjusted. Changing the density of LEDs affects the strip's lighting effect, with higher densities providing better linearity. Additionally, adjusting the arrangement of LEDs impacts the brightness and voltage drop across the strip, allowing for tailored lighting performance.
2. Customizing PCB Boards:
LED strips can have customized PCB boards to suit different installation environments. For narrow spaces, thinner strips can be produced, while for higher brightness needs, wider PCBs may be used to enhance heat dissipation. Moreover, double or triple-row LED arrangements can be achieved by expanding the PCB width to deliver the desired lighting effects.
3. Customizing Waterproofing:
Depending on the intended usage environment, various waterproof levels can be applied. For instance, IP20 indicates no waterproofing, IP65 is gel-coated, and IP67 uses tubing or extrusion methods for waterproofing. For outdoor applications like neon LED strips, IP67 is commonly used, and IP68 offers the highest level of waterproofing with considerations for plug and cable sealing to ensure complete water resistance.
This level of customization ensures that clients get the most suitable LED strip solutions for their specific projects, whether for indoor decor or demanding outdoor lighting installations.

4. Customizing Color Temperature:
We offer standard color temperatures of 3000K, 4000K, 6000K, 8000K, and 10000K. Additionally, we can customize specific color temperatures based on customer requests. In certain environments, strict requirements for color temperature are essential. If customers provide the x and y chromaticity coordinates on the color spectrum chart, we can produce a color that precisely matches their needs.
This level of customization ensures that lighting solutions not only meet aesthetic preferences but also adhere to technical specifications for specialized environments.

5. Custom Color Steps:
Our standard offering for LED strip products is three-step color binning, ensuring consistency in light output. However, if customers require finer precision, we can provide a one-step binning process, which guarantees even tighter control over color consistency.
6. Custom Color Rendering Index (CRI):
Some customers require specific CRI (Color Rendering Index) standards. Achieving a CRI of 90 is relatively straightforward with current LED technology. However, for higher CRI values, like 95, we need to determine if the requirement is for an average CRI or if specific parameters like R9 (which represents red tones) must also be high. A CRI of 95 or higher is typically needed in specialized environments like photography studios. We can fully meet customer demands for CRI, ensuring optimal color accuracy for any application.
7. Custom Packaging:
Single-color LED strips are often used for home and commercial decor, and we provide packaging customization to cater to wholesalers. This includes custom labels, special bags, boxes, and display stands, offering a one-stop service experience for our clients.
Industry Expertise: We bring years of customization experience, having served notable clients such as Ford and Best Buy with OEM and ODM services. Our products adhere to ISO9001, CE, RoHS, and UL standards, ensuring quality and reliability.

Not necessarily. The choice between constant current or constant voltage LED strips depends on the project requirements.
- Color consistency issues:
This is due to differences in the manufacturing process between COB LED strips and SMD LED strips. SMD LED strips involve sorting and binning LED chips to ensure color consistency on a single strip. In contrast, COB LED strips apply phosphor directly onto the chips on the PCB, skipping the binning step, which can lead to less uniform color. - Lower power output:
Because COB LED strips have denser chips, heat dissipation is a challenge. Their maximum power is generally around 14W per meter, while SMD LED strips, which use chips with heat-dissipating brackets, can reach up to 18W per meter. - Lower luminous efficiency:
Currently, COB LED strips have a maximum luminous efficiency of around 120LM/W. SMD LED strips with high-power chips can achieve 160-170LM/W. For applications requiring more than 120LM/W, SMD LED strips are preferable. - Higher failure rate in waterproof applications:
The flip-chip design of COB LED strips tends to have a higher defect rate in waterproof configurations compared to SMD LED strips.
Constant current LED strips include built-in ICs that maintain a stable and consistent current regardless of voltage fluctuations.
Yes, LED strips are designed for long-term operation due to their energy efficiency and durability. High-quality LED strips typically have a lifespan of 25,000 to 50,000 hours, meaning they can run 24 hours a day for several years without issues.
