In electronics, 2835 denotes a common surface-mount LED package size, measuring approximately 2.8 by 3.5 millimeters. The 2835 package is widely used in LED strip lighting and general illumination, and is often marketed as offering higher efficiency and brightness density than some older package types. It is commonly used in 12- or 24-volt strip configurations, typically arranged in series groups with current-limiting components to control brightness and power consumption.
