This 3W RGB LED from Adafruit delivers bright, full-colour illumination from a compact high-power package. Each red, green, and blue die handles up to 350mA continuous current (1A peak), producing a combined output of approximately 110 lumens.
The LED comes pre-mounted on an aluminium PCB that serves as both a mounting base and partial heatsink. This is a common-anode configuration, so all three colour channels share a single positive connection.
Key Features
- High Power Output – 3W total with ~110 lumens
- Full RGB Colour Mixing – Independent red, green, and blue dies for millions of colours
- Common Anode – Shared positive connection for all three channels
- Aluminium PCB Mount – Pre-mounted on a metal-core PCB for heat dissipation
Specifications
- Power – 3W
- Luminous Output – ~110 lumens
- Configuration – Common anode
- Current per Channel – 350mA continuous, 1A peak
- Mounting – Aluminium PCB
Ideal For
- RGB lighting projects
- Colour-mixing experiments
- Custom lamp and fixture builds
- Stage and effects lighting
Package Contents
- 1× 3W RGB LED on aluminium PCB
Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring arrangement where several LEDs or LED segments share a common positive (anode) terminal and are switched individually on their negative (cathode) side. Common-anode and common-cathode parts, such as RGB LEDs, seven-segment displays, matrices and strips, are not interchangeable without a suitable driver.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
