2835 vs 3030 vs 3535: The Ultimate SMD LED Selection Guide
March 28, 2025
SMD (Surface-Mount Device) LEDs are widely used in residential, commercial, and industrial lighting. Among them, 2835, 3030, and 3535 are the most common LED package types. Each has distinct characteristics in brightness, heat dissipation, and cost, making it essential to choose the right one based on specific application requirements.
1. Comparison of Brightness, Heat Dissipation, and Cost
| LED Type | Size (mm) | Brightness | Heat Dissipation | Cost |
| 2835 | 2.8 × 3.5 | High luminous efficiency, ideal for indoor lighting | Moderate, requires optimized PCB design | Low, suitable for large-scale applications |
| 3030 | 3.0 × 3.0 | Higher brightness, widely used in commercial lighting | Good heat dissipation, compact package | Medium, cost-effective |
| 3535 | 3.5 × 3.5 | Ultra-high power, suitable for industrial and outdoor lighting | Excellent heat dissipation, often with ceramic substrates | High, advanced technology |
2. Best Applications for Different SMD LEDs
✅ 2835 – Best for Residential & Office Lighting
- High efficiency and low heat generation, perfect for LED bulbs, panel lights, and downlights.
- Affordable and energy-efficient, making it an excellent choice for mass production.
✅ 3030 – Versatile Choice for Commercial Lighting
- Brighter output and good thermal performance, ideal for shopping malls, supermarkets, and streetlights.
- A well-balanced option in terms of performance, durability, and cost.
✅ 3535 – High-Power LED for Industrial & Outdoor Use
- Designed for high-power LED floodlights, stadium lighting, and UV sterilization lamps.
- Uses ceramic substrates for exceptional heat dissipation, ensuring long-term stability under high-power operation.
3. How to Choose the Right LED?
Depending on your application, here’s how to select the most suitable SMD LED:
- For energy-efficient indoor lighting, 2835 is the best choice.
- If you need higher brightness for commercial spaces, 3030 provides a great balance of performance and cost.
- For high-power, high-durability applications, 3535 is the ideal solution.
