L-53SRC-J4 LED Lamp - Specifications, Features & Local Buying Guide

Overview of the L-53SRC-J4 LED Lamp

The L-53SRC-J4 LED lamp is a compact, high-efficiency illumination module designed for signage, indicator panels, and small-area lighting. This page summarises its electrical and mechanical specifications, mounting and connector guidance, compatible accessories, and practical notes for South African makers, students, technicians and procurement teams buying locally.

Key features

• High luminous efficacy LED array with multiple colour options (single-colour red/green/blue and warm white variants).
• Low-profile aluminium housing with screw or snap-mount options for panel installations.
• Integrated current-regulated driver or raw LED versions depending on SKU; check exact model suffix for driver presence.
• Standard 2.54mm JST or Molex-compatible connector variants for rapid prototyping and replacements.

Electrical specifications (typical)

Mechanical & connector details

Typical dimensions are compact (example: 53 mm length x 9 mm height, depending on bezel). Mounting choices include front-panel snap-fit or two-screw flange. Connector pins use common hobby-standard pitch for fast replacement. When ordering for assembly, select the correct connector option to match existing harnesses.

Why spec clarity matters

Using the correct forward voltage and current spec prevents premature failure and ensures consistent brightness. For multi-colour modules, balance currents across channels and add series resistors or a proper constant-current LED driver where needed.

Selecting the Right Variant: Driver vs Raw LED

If you need plug-and-play operation from a 12 V or 24 V supply, choose the driver-integrated L-53SRC-J4 variant which includes regulation and basic protection. For microcontroller projects (Arduino, ESP32) or custom LED drivers, the raw LED module lets you control brightness with PWM but requires a suitable constant-current source or series resistors.

Compatibility & accessory guidance

• Power: Match supply voltage and ensure current headroom. Example: if a module draws 60mA total, pick a 500mA supply to leave room for expansion and reduce stress.
• Connectors: Choose JST 2-pin or Molex KK variants to match cables used in your project.
• Mounting: confirm bezel cut-out dimensions for a flush panel fit; order spare mounting clips where available.

Specification checklist for procurement teams

• Confirm SKU exactly (colour, viewing angle, connector type, driver inclusion).
• Request sample units where possible for visual and fit testing before bulk buy.
• Ask suppliers for typical lead times; for local stock expect faster collection from Samrand or Cape Town branches, otherwise factor import lead times (estimates vary).
• Obtain VAT invoices for accounting and education discounts if applicable.

Example wiring: raw LED module to microcontroller (ASCII)

Microcontroller PWM pin --- 220 resistor --- LED +
LED - ----------------------------- GND

Use PWM frequency above 1 kHz to avoid visible flicker on dimming. For multi-colour modules, use one PWM channel per colour channel and ensure shared common ground.

Local pricing & availability notes (South Africa)

Typical unit prices for small quantities vary by variant; estimated retail range for similar indicator LED modules in South Africa is between ZAR 25 and ZAR 150 per unit depending on driver inclusion and bezel finish (estimate only). For project budgets, include shipping or branch collection costs and allow extra lead time for non-stocked SKUs.

Where to look at Communica

Search Communica categories for Connectors & Wiring, LEDs & Lighting, and Enclosures to pair the L-53SRC-J4 with harnesses, drivers and panel parts. Check branch stock (Samrand, Pretoria CBD, Cape Town) if you need same-day collection.
