Green 5mm LED

Green 5 mm LED – Displays Category
The Green 5 mm LED is a compact, high‑visibility light‑emitting diode that snaps onto a standard 2 mm‑pitch breadboard or wires directly to a solder‑free prototyping board. Emitting a bright, true‑green light at just 20 mA, it’s the perfect visual indicator for circuits ranging from simple on/off switches to complex sensor‑driven projects. Designed for durability, the lead‑frame is made of nickel‑plated copper, and the epoxy‑sealed lens resists impact, making it ideal for classroom labs and after‑school makerspaces.

What students will learn
Working with this LED introduces learners to fundamental concepts such as voltage, current limiting, polarity, and the physics of semiconductor light. By wiring the LED into circuits with resistors, microcontrollers, or phototransistors, students explore Ohm’s Law, pulse‑width modulation, and basic programming logic; all while instantly seeing the results of their code or circuit changes in vivid green light.

Key features

• Standard 5 mm radial package, compatible with most prototyping boards
• Forward voltage: 2.0 V ± 0.2 V (typical) – ideal for 3.3 V or 5 V systems
• Brightness: ≥ 800 mcd, visible in daylight and low‑light environments
• Long lifespan: > 50,000 hours, low power consumption
• Lead length: 2 mm for secure, solder‑free connections

Why it’s great for STEAM education
The Green 5 mm LED bridges the gap between abstract theory and tangible results, turning mathematical equations and code into a glowing, real‑world output. Its simplicity lets students focus on problem‑solving, while its versatility supports interdisciplinary projects, from creating interactive art installations (Art) to building environmental monitoring stations (Science) and programming responsive robotics (Engineering & Technology). By integrating this LED into hands‑on lessons, educators can spark curiosity, reinforce core STEM concepts, and inspire the next generation of innovators.
