## Description

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. Key Features Power – 1 W Luminous Output – 90 lumens Colour Temperature – 6000 K (cool white) Beam Pattern – 140° lambertian Recommended Drive Current – 350 mA (constant current) Forward Voltage – ~3 V Mounting – Pre-mounted on aluminium PCB heatsink Solder Pads – Two + and two − pads for easy connection Ideal For DIY flashlights and headlamps High-brightness indicator and task lighting Bike lights and portable lighting projects Package Contents 1× 1 W cool white LED on aluminium heatsink PCB Tip: For best results, use a constant current driver at 350 mA. For a quick setup, two alkaline AA batteries connected in series will drive the LED at approximately 200 mA with no resistor needed.
