How to Choose: SMD2835 vs SMD5050 in Red / Infrared LED Chips
| Feature | SMD2835 (Single-Chip) | SMD5050 (Triple-Chip) |
|---|---|---|
| LED Structure | Each LED contains 1 chip | Each LED contains 3 chips |
| Emission Power | Stable output, ideal for general IR/red light applications | Higher radiant intensity, suitable for high-output applications |
| Beam Spread | More uniform, ideal for short-range or surface use | Stronger projection, ideal for long-range or focused lighting |
| Application Focus | Cost-effective for home therapy, plant lighting, basic sensing | Professional-grade for therapy, industrial, night vision |
| Standard Pack Quantity | 4000 pcs / pack | 1000 pcs / pack |
| Power Options | 0.2W / 0.5W | 0.2W / 0.5W |
Recommendation: Choose SMD5050 for higher brightness, deeper IR penetration, or professional-grade usage. Choose SMD2835 for cost-effective, standard-use applications.
