2835 SMD LED is one of the most popular surface mount device LED packaged that used in lighting and indication project.
When we mention about the red color, it's a wide range of wavelength in spectrum, which means we can name those LED that emits wavelength range in 610-680nm as "red color LED"
The 2835 refers to its size, the length and width in thenths of milimeter: 2.8x3.5mm. This size are very similar as 3528 SMD LED. But 2835 typically having a larger emitting surface and better thermal performance. And its height usually around 0.8mm.
For Red SMD LED, BESTLED factory can produce it with 625nm LED, 660nm LED, 640nm LED are the most popular type. For the luminous intensity are measure in millicandelas, we mark it as "mcd". Value range widely from 200-2000 + mcd. And 200-600mcd for standard versions, over 1500mcd will for high brightness type. Of couse the brightness value are also depends on the drive current and chip's quality and size.
Red SMD LED in 2835 package is a workhorse component that combines efficiency, reliability and excellent thermal properties in a compact industry-standard package. For red color, its low forward voltage and high output. Which make it ideal for both energy sensitive and performace driven applications.
