L-59SURKCGKC LED Lamp Specifications: Complete Technical Guide for South African Makers

Overview: What the L-59SURKCGKC LED lamp specification means

The L-59SURKCGKC LED lamp specification identifies a compact solid-state light source with distinct electrical, optical and thermal parameters. This guide explains the typical spec sheet items you will see for an LED lamp of this naming style, how to interpret those values for electronics projects, installation and procurement in South Africa, and which measurements matter most for makers, students and technicians.

Key spec categories

• Electrical: forward voltage (Vf), rated current, power consumption (W), surge tolerance
• Optical: luminous flux (lm), luminous efficacy (lm/W), colour temperature (CCT, K), colour rendering index (CRI)
• Mechanical and environmental: package, beam angle, mounting, operating temperature range
• Thermal: thermal resistance (°C/W), recommended heatsinking or PCB copper area

Typical electrical specifications and what they mean

A manufacturer part like L-59SURKCGKC will include a nominal forward voltage (Vf) and recommended drive current. For single LED modules these are often listed as Vf = 2.8-3.6V (for warm-white/white types the Vf varies by bin and colour) and If = 350mA or 700mA for higher-power types. Power (P) is computed as P = Vf × If. For example, Vf = 3.2V at If = 350mA gives P = 1.12W.

Specification comparison table (example values)

The numeric examples above are illustrative. Always read the product datasheet for the exact L-59SURKCGKC values before final design or procurement. For broad component browsing and possible cross-references, view the Communica l-59surkcgkc-led-lamps-for-electronic-projects page.

Internal wiring and driver basics

LEDs require constant-current drive for predictable brightness and longevity. For a single L-59SURKCGKC module, choose a constant-current LED driver rated to the module's If. If you need to place multiple modules in series, add their Vf values to find the total driver voltage requirement. For parallel strings, ensure each string has current regulation.

Basic formulae:

• P = V × I (power in watts)
• For series LEDs: Vtotal = Vf1 + Vf2 + ...
• Resistor approximation (low-power prototypes): R = (Vsource - Vf) / I

Example resistor calculation for a simple prototyping setup (use only for low-current, non-critical builds): If Vsource = 12V, Vf = 3.2V, If = 20mA then R = (12 - 3.2) / 0.02 = 440 ohms. For modules run at higher currents, use a proper LED constant-current driver instead of series resistors.

Thermal management, lifetime and dimming

Heat is the primary enemy of LED life and performance. Thermal resistance (°C/W) from junction-to-case and case-to-ambient indicates how effectively heat must be removed. Lower thermal resistance means easier cooling. For an example module with thermal resistance 10 °C/W at 1.12 W dissipation, expect a junction-to-ambient rise of roughly 11.2 °C above ambient, assuming correct mounting.

Heatsinking and PCB recommendations

• Follow the datasheet recommended copper area if mounting to PCB.
• For higher currents, attach to an aluminium heatsink with thermal interface material.
• Maintain good airflow in enclosed fittings to limit ambient temperature rise.

Dimming and control options

Dimming may be achieved with PWM drivers or analog current reduction. PWM preserves colour and efficacy better than reducing current. If using microcontroller PWM, ensure the LED driver or a MOSFET switch is rated for the module current and switching frequency.

Wiring example (series single-driver):

  +12V --- LED driver (constant current) ---+--- L-59SURKCGKC --- GND

For multiple modules in series:
  +V --- driver (Vout >= sum of Vf) --- MODULE1 --- MODULE2 --- ... --- GND

Troubleshooting common issues

• No light: check driver polarity, verify driver output current and module Vf, test with multimeter.
• Dimming/ flicker: confirm driver type; replace incompatible dimmer with LED-compatible constant-current driver.
• Overheating: reduce drive current, improve heatsink, or add airflow.

For students and makers in South Africa, practical considerations include local supply continuity and VAT invoicing for educational purchases. Communica provides VAT invoices and branch collection options; check Branches & Trading Hours for branch locations and pickup policies.

When specifying L-59SURKCGKC for a project or procurement, request the product datasheet and confirm exact Vf, If, luminous flux and thermal resistance. For brand and alternative part searches, use the top-rated LED lamps for educational purposes index to find stocked manufacturers and compatible modules.

Explore brands and consider pairing modules with drivers and enclosures from the collections page for complete assemblies.

Practical South Africa example and cost note

Example: A small signage build using five L-59SURKCGKC modules in series (assume Vf each = 3.2V, If = 350mA) needs a driver with Vout >= 16V and constant current 350mA. Estimated component cost for modules and a suitable driver in South Africa can vary; budget approximately ZAR 150-500 per module and ZAR 200-800 for a driver depending on brand and stock - actual prices should be checked on the product pages or via account quotes.
