LED SMD 5050 VS 2835 VS 3528

So what do these numbers mean? Is one better than the other? Well, the numbers actually represent the package size.

SMD Type Dimensions Watt
SMD5050 5.0mm x 5.0mm 0.24
SMD 2835 2.8mm x 3.5mm 0.15
SMD3528 3.5mm x 2.8mm 0.08

SMD stands for Surface Mount Device. SMD 2835 is the newest SMD configuration and offers the best cost / performance. It is significantly smaller than the SMD5050 and has better heat dissipation.

Advantages of SMD 2835 vs 3528

  • Chip direct conduction fins improve the heat dissipation performance allowing it to withstand higher current (40-60mA)
  • 2-3 times larger heat sink than 3528, allowing excellent heat dissipation
  • Slower light decay of LED chip life
  • Oversized light-emitting surface improves the rate of light up to 90%.
  • Ultra-thin structure solves the 3528’s long-standing problem.
  • 2-3 times higher luminous efficiency than 3528; capable of up to 90-100 Lumens per Watt.
  • The costs have been reduced by up to 20% vs the older 3528 design.
