Where to Buy L-53SRC-C MOD LED Lamps in South Africa - Stock, Specs & Brands at Communica

Overview: L-53SRC-C MOD LED Lamp Features & Use Cases

The L-53SRC-C MOD is a popular 5mm (T-1 3/4) red LED indicator from Kingbright, known for its clarity and reliability in a wide range of electronics applications. Whether you're building educational kits, prototyping circuits, or maintaining industrial panels, these LEDs deliver consistent brightness and are easy to integrate into standard breadboards or PCBs.

• 5mm round, clear lens, red-emitting LED
• Wide viewing angle (typically 60 degrees)
• Efficient for low-current indicator circuits and logic displays
• Widely compatible footprint (fits most protoboards and PCBs)

Key Specifications: L-53SRC-C MOD LED

Compatible Applications & Typical Use in South Africa

L-53SRC-C MOD series LEDs are widely deployed in:

• Arduino and Raspberry Pi prototypes (breadboard indicator lights)
• School, college and university engineering kits
• Industrial controls and status displays
• DIY maker projects - panel mounts, logic circuits, basic displays
• Repairs for legacy equipment with through-hole LEDs

Communica keeps Kingbright and similar LEDs in stock for prompt collection or dispatch. Lead times are short, and educators benefit from VAT-taxed invoices and bulk pack discounts where applicable. Drop into a local branch or browse online for up-to-date part availability.

Selection & Sizing Guide: How to Choose and Use L-53SRC-C MOD LEDs

When working with through-hole LEDs, correct current limiting is essential to prevent damage and ensure optimal brightness. For 5V logic circuits (common with Arduino or Raspberry Pi), use Ohm's law to calculate your series resistor:

• V_supply = 5 V (microcontroller output)
• V_f = 2.0 V (LED forward voltage)
• I_LED = 20 mA (recommended current)

Availability, Purchasing, and Collection in South Africa

South African customers can check live stock for L-53SRC-C MOD on Communica's product collections. Availability is visible online for all branches, and you can reserve items for pickup at Samrand (Centurion), Pretoria CBD, or Cape Town. Lead times are typically 1-2 business days for in-branch collection, and Communica's stores are open extended hours for student and professional convenience. VAT invoices are provided for education or business use, with bulk order support for schools and universities.

Troubleshooting & Tips

• If the LED won't light up, double-check polarity - the flat edge marks the cathode.
• Over-brightness or LED damage? Reduce current by increasing your series resistor value.
• For visible indicators in bright rooms, operate closer to the 20 mA rating.
• For battery-powered projects, lower the current to 10 mA to save energy - L-53SRC-C MOD remains visible at reduced brightness.
