Specifications

Why Choose This?

• Bright, uniform green output at 520-530nm wavelength for clear visual indication
• Low forward voltage (~3V) and 20mA current draw minimize power consumption
• Standard 3mm T-1 package fits breadboards, perfboards, and PCB through-hole footprints directly
• 2.54mm lead pitch matches standard prototyping grids - no adapters needed
• Pack of 10 gives you spares for multiple circuits, testing, and replacements
• Wide operating temperature range (-25 degreesC to +85 degreesC) suits indoor and outdoor applications
• 100% authentic from trusted suppliers with verified quality
• 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse
• Expert technical support included for circuit design and troubleshooting

Project Ideas

• Power-On Indicators: Add a green LED with a current-limiting resistor to any 3.3V or 5V circuit to show power status at a glance.
• Arduino & Raspberry Pi Projects: Drive directly from GPIO pins through a 150Ohm resistor for status signals, traffic light simulators, or binary counters.
• Traffic Light Model: Combine with red and yellow 3mm LEDs to build a working traffic signal for learning sequential logic and state machines.
• Battery Level Indicator: Use a row of green LEDs with a comparator circuit or LM3914 to display charge level visually.
• LED Chaser / Knight Rider Effect: Wire all 10 LEDs in a row and control with a 555 timer + CD4017 decade counter for classic running-light animations.
• Sensor Feedback Displays: Pair with temperature, light, or proximity sensors to provide real-time visual feedback in embedded systems.
• PCB Prototyping: Solder onto custom PCBs as diagnostic or status indicators during development and testing phases.
• Learning & Education: Perfect for students learning Ohm's law, Kirchhoff's laws, and basic semiconductor behavior hands-on.

Quick Start Guide

• Identify polarity: The longer lead is the anode (+), the shorter lead is the cathode (). The flat edge on the lens body also marks the cathode side.
• Calculate your resistor: R = (V_supply V_forward) / I_forward. For a 5V supply: (5V 3V) / 0.02A = 100Ohm. Use 100Ohm-150Ohm for safe operation.
• Connect: Wire the resistor in series with the anode, connect cathode to ground, and apply power. The LED should glow green immediately.
• With Arduino: Connect anode through a 150Ohm resistor to any digital pin, cathode to GND. Use digitalWrite(pin, HIGH) to turn on.

What's in the Box

• 10 x 3mm Green LEDs (through-hole, pre-sorted and tested)
• Anti-static packaging to protect components during transit
• Documentation and support materials
