What is the difference between SMD2835 LED and SMD3528 LED?
We should firstly understand what is SMD, SMD means "Surface Mount Diode", by soldering the LED chips on the PCB, the LEDs are evenly arranged to form a complete strip light.
The size of SMD2835 LED is 2.8*3.5mm, which shows the rectangle of light in the center; the size of SMD3528 LED is 3.5*2.8mm, which shows a round light-emitting center. Although roughly the same size in appearance, 2835 SMD LED as an upgraded version of 3528 LED has a larger light-emitting surface area and better heat sink, its light output is 2 to 3 times that of 3528 chip, so 2835 LED strip can work longer than 3528 LED strip;
2835 LED strip lighting is brighter than 3528 LED, the 2835 LEDs offer standard and high density of up to 390 lm/ft in a single row and the brightest LED strip option on the market with up to 1300 lm/ft in three and four rows; the 2835s are widely used and can be used for indoor and outdoor DIY lighting, as well as auxiliary lighting in dim environments, holiday decorative lighting and architectural lighting.
Although 2835 LED has many advantages, but 3528 LED as the earliest LED chip, the market share is higher, with good cost performance. If you are looking for more high efficient and brighter products, 2835 LED is more suitable for your needs, if you want to get lower cost LED strip (Between 2835 LED and 3528 LED), SMD3528 is more suitable. Both of them support DC12/24V low voltage input, with CRI95+, and can be customized with color, length and waterproof level.
