5mm Round Red Diffused Led (Pack of 10)
Get a pack of 10 high-quality 5mm round red diffused LEDs - the most widely used indicator LED in electronics. The diffused lens provides a soft, evenly distributed red glow, making these LEDs ideal for status indicators, panel lights, breadboard projects, and decorative circuits. Compatible with standard 5mm LED holders and easy to drive with a simple resistor, these are an essential staple for every electronics toolkit. Available from The Engineer Store, Bengaluru with fast shipping and dedicated support.

Key Features
- Diffused Lens Design: Frosted housing scatters light evenly across a wide 120 degrees angle, eliminating harsh bright spots and providing uniform visibility from multiple directions.
- Standard 5mm Form Factor: Universally compatible with breadboards, perfboards, PCBs, and standard 5mm LED mounting clips and bezels.
- Low Power Consumption: Draws only 20mA at typical forward voltage of 2.0V, making it efficient for battery-powered and microcontroller-driven projects.
- Easy Polarity Identification: Longer anode lead and flat cathode edge on the housing make correct orientation simple, even for beginners.
- Wide Operating Temperature: Reliable performance from -25 degreesC to +85 degreesC, suitable for both indoor projects and outdoor enclosures.
- Bright Red Output: 620-635nm wavelength delivers a vivid, easily recognizable red that is the industry standard for error indicators, power-on lights, and warning signals.
- Value Pack of 10: Enough LEDs for multiple projects, prototyping iterations, or classroom experiments without running out.
Why Choose This?
- 100% authentic LEDs sourced from trusted component suppliers
- 1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse
- Expert technical support to help with resistor calculations, wiring, and project integration
- Consistent brightness and color across all 10 LEDs in the pack
- Beginner-friendly with straightforward two-pin through-hole design
How to Use / Quick Start Guide
- Step 1 - Identify Polarity: The longer lead is the anode (+) and the shorter lead with the flat edge on the housing is the cathode (). Always connect correctly to avoid damage.
- Step 2 - Calculate the Resistor: Use the formula R = (Vsupply Vf) / If. For a 5V supply: R = (5V 2.0V) / 0.02A = 150Ohm. Use the nearest standard value (150Ohm or 220Ohm for extra safety).
- Step 3 - Connect in Circuit: Wire the resistor in series with the LED. Connect the anode through the resistor to the positive supply and the cathode to ground.
- Step 4 - Test: Apply power and verify the LED glows with a soft, diffused red light. If it doesn't light up, reverse the polarity.
- Step 5 - Microcontroller Integration: Drive directly from Arduino, ESP32, Raspberry Pi GPIO, or any 3.3V/5V logic pin through an appropriate current-limiting resistor.
Common Resistor Values for Popular Supply Voltages
| Supply Voltage | Recommended Resistor |
| 3.3V | 68Ohm - 100Ohm |
| 5V | 150Ohm - 220Ohm |
| 9V |
