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 style for multi-colour LEDs where the positive side is shared and each colour channel is controlled on the negative side. This matters because common-anode and common-cathode LED strips are not interchangeable without a suitable driver.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
