Buy 5mm Diffused Dome Bright Green LED (L-53SGD) in South Africa - In Stock at Communica

Features & Specifications: L-53SGD 5mm Green LED

• Lens: 5mm (T-13/4), diffused, dome-top design for wide viewing angle
• Colour: Bright green (typ. 565nm peak wavelength)
• Forward Voltage: ~2.0V to 2.4V typical at 20mA
• Luminous Intensity: Up to 8 mcd at rated current (varies by batch/spec)
• Viewing Angle: 60-80 degrees (diffused for uniform light)
• Polarity: Cathode marked, standard 2-lead through-hole

This general-purpose LED is compatible with breadboards, PCBs, Arduino, and Raspberry Pi outputs (with appropriate resistors). Use it for power status, signal testing, project feedback, or home automation indicators. Popular among educators for lab demonstrations and practical assignments.

Advantages of Diffused Dome LEDs

• Softer, wider light spread versus clear lens, ideal for close-up panels or displays
• No harsh hotspot - easy on the eyes in indicator clusters
• Readily available, affordable for bulk use and experiments

Selection & Application Guidance

• Check supply voltage and current limiting resistor. For 5V circuits, use Ohm's law to select:

Resistor Calculation Example:
R = (V_{supply} - V_{LED}) / I_{LED}
Suppose V_supply = 5V, V_LED = 2.1V, I_LED = 20mA R = (5 - 2.1) / 0.02 = 145. Choose standard value 150 (nearest preferred value).

• Observe correct polarity: flat edge/short lead = cathode (-), round edge/long lead = anode (+)
• Safe for use on solderless breadboards, perfboard, and through-hole PCB projects
• Bright green is highly visible even in moderate ambient light - excellent for signal tracing or status indication
