1. 3528 SMD LED

The 3528 SMD LED is a compact and versatile option widely used in decorative lighting, backlighting, and displays. Its dimensions measure 3.5mm x 2.8mm. This size is particularly favored for its low power consumption and can typically emit 10-14 lumens at 120 mA, making it suitable for applications with less illumination needs.

2. 5050 SMD LED

The 5050 SMD LED, measuring 5.0mm x 5.0mm, offers a higher output than the 3528 version. It is capable of producing 16-24 lumens while drawing more current, typically 150 mA. It's often used in LED strips and lighting fixtures that require a brighter output and has become popular in RGB lighting applications because it can incorporate multiple colors in one chip.

3. 5630 SMD LED

The 5630 SMD LED is larger than both the 3528 and 5050 sizes, with dimensions of 5.6mm x 3.0mm. Known for its exceptional brightness, it can generate up to 20-22 lumens per chip at 150 mA. This makes the 5630 a top choice for commercial lighting fixtures where brightness is a key factor.

4. 5730 SMD LED

The 5730 SMD LED is another large chip, with dimensions similar to the 5630 at 5.7mm x 3.0mm. However, it typically produces even more light, approximately 22-25 lumens. This size has gained traction in applications requiring high intensity lighting, such as in floodlights and industrial settings.

5. 3014 SMD LED

The 3014 SMD LED measures 3.0mm x 1.4mm and is designed for efficiency rather than brightness. With a lumen output of around 8-10 lumens, this size is commonly used in tasks where space is limited, such as in small light fixtures and accent lighting. Its compact size and efficiency make it ideal for intricate designs.

6. 2835 SMD LED

The 2835 SMD LED has dimensions of 2.8mm x 3.5mm and is recognized for its balance of size and power. This LED can provide around 20 lumens per chip, making it popular in both indoor and outdoor lighting applications as well as in LED strips and panels.

Conclusion

Understanding the common SMD LED sizes is essential for making informed decisions in your LED lighting projects. From the compact 3528 to the powerful 5730, each size has its unique benefits tailored to various applications. When selecting an SMD LED, consider the space, power consumption, and brightness required to optimize your lighting solutions effectively.
