Overview: What is the L-7113ZGC LED Lamp?
The L-7113ZGC is a widely used 5mm (T-1 3/4) round LED lamp emitting a rich green light. Manufactured by reputable brands such as Kingbright, this through-hole LED combines energy efficiency, robust intensity, and compact form factor, making it popular for indicators, status displays, educational kits, and low-voltage signaling in South African hobby and professional applications. Local availability through veteran distributors, like Communica, ensures easy sourcing for both procurement teams and individual makers.
Technical Specifications Table
| Attribute | Typical Value | Range/Note |
|---|---|---|
| LED Colour | Green | Peak 565nm (typ) |
| Forward Voltage (VF) | 2.2V | 2.0-2.5V |
| Forward Current (IF) | 20mA | Max 30mA |
| Luminous Intensity | 30mcd | 22-45mcd (@20mA) |
| Viewing Angle | 60 degrees | - |
| Package | 5mm (T-1 3/4) | Clear Lens, 2-pin |
Major Features & Advantages
- Bright, high-visibility green emission-ideal for clear indication in day or low light conditions.
- Low power consumption (under 0.05W typical at 20mA), supporting battery operation and embedded controller use.
- Long service life (typical >50,000 hrs under correct drive).
- Through-hole leads simplify breadboarding, prototyping, and soldered PCB mounting.
- Widely compatible with standard 5mm LED holders, bezels, and panel-mount accessories-also stocked at Communica.
Selecting the L-7113ZGC: Decision Factors
- Check required colour/wavelength for your use case-green (565nm) matches diagnostics, UI indicators, and teaching boards.
- Verify voltage and current limits versus your circuit-exceeding 2.5V or 30mA can cause premature failure.
- Ensure mechanical fit-5mm diameter, correct lead spacing for your project or board layout.
- Consider viewing angle if wide or narrow indication is desired (60 degrees standard for this series).

Resistor Calculation & Example Wiring
To avoid overdriving the LED, a current-limiting resistor is essential. Use Ohm's Law (V = IR) for calculation:
| Parameter | Value | Example Source |
|---|---|---|
| Supply Voltage (Vs) | 5V | MCU, Arduino |
| LED Forward Voltage (VF) | 2.2V | L-7113ZGC |
| Target Forward Current (IF) | 20mA (0.02A) | Standard brightness |
Required resistor: R = (V_s - V_F) / I_F = (5V - 2.2V) / 0.02A = 140Ohm. Use the next-highest standard value, e.g., 150Ohm, to ensure safe current limit.

Resistor
- "A" denotes anode (longer lead), "K" is cathode (shorter lead, often flat-side or flagged). Connect the resistor in series with the LED's anode for standard single-LED operation.
Troubleshooting Notes
- LED does not illuminate: Confirm polarity; reverse connection prevents conduction (no damage at low voltage).
- Dim output: Check for excessive resistor value, low drive voltage, or multiple LEDs in series exceeding supply voltage.
- Premature burnout: Running above 30mA or without a resistor will deteriorate LED rapidly.
