In the LED market, both 2835 SMD LED and 5730 SMD LED are popular SMD LED package in LED lighting project.
From the name we can tell, the size of 2835 LED will be 2.8x3.5mm and 5730 LED is 5.7x3.0mm. Compare with 2835 SMT LED, the 5730 is a step up in power class. Normally 1 single 5730 LED are able to replace 2-4 standard 2835 LEDs in terms of total light output with the same chip. Simplifying circuit design and reducing component count, but with greater thermal management demands.
The 2835 LED can be Red SMD LED, Green SMD LED, Yellow LED or IR LED. It's engineered for efficienxy and density. Its superior thermal management design allows it to be driven relatively hard while remaining cool, making it ideal for packing many LEDs close togehter to create uniform, high density light panels.
Same as that, 5730 are also available in IR LED, Amber LED ect. It's designed for higher single unit output. It's larget size accommodates a bigger chip and provides more surface area, aiming to deliver more lumens from a single point.
In short, choose the 2835 for small, dense and efficient designs where uniformity and thermal management in a compact space are key. Choose the 5730 for larger, brighter and simpler designs where maximizing light output from fewer points is the priority.
