What is the different between SMD2835 and SMD3528 LED Corn lamp? The different between SMD2835 and SMD3528 Item Brightness Current Power (W) Structure Heat sink area Effect of heat dissipation Emitting angle Light emitting area Thickness Efficacy (LM/W) SMD2835 22-24lm 40-60mA 0.1-0.2 vertical big Optimal 120° 9.18mm 0.8mm 130-150lm 24-28lm 28-30lm SMD3528 4-5;5-6lm 20mA 0.06 the vertical no poor 100° 4.5mm 2.2mm 90-100lm 6-7;7-8lm VS SMD2835 SMD3528 Core advantage of SMD 3528 1, The vertical structure: Chip direct conduction fins to improve the heat dissipation performance, which can withstand the higher current (40-60mA) 2, Large heat sink: larger than 3528 heat sink 2-3 times, excellent heat dissipation design, light decay of LED chip life more secure; , 3.Oversized light-emitting surface: to improve the rate of light: up to 90%. 4, Ultra-thin structure:to solve the 3528been long-standing problem spot; 5, High optical ...
