An ultra-bright 1 W cool white LED pre-mounted on an aluminium PCB heatsink, making it easy to solder and integrate into projects. With 90 lumens output in a 140° lambertian pattern, it delivers bright, even illumination ideal for flashlights, headlamps, and general lighting.
The LED produces a cool 6000 K pure white light. It is best driven with a constant current source at 350 mA, but can also be under-driven for simpler setups — two alkaline batteries connected directly (no resistor) will draw approximately 200 mA at ~3 V for a basic bright lamp.

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
