Technical Specs & Certifications
The request contains a fundamental technical misconception that requires clarification before addressing specifications. A 4-pin LED light connector is a passive electrical component solely responsible for mechanical attachment and electrical signal/power transmission between an LED driver and an LED module or strip. It does not generate light and therefore possesses no inherent lumens per watt (lm/W) output, Color Rendering Index (CRI), or standalone IP rating. These performance metrics apply exclusively to the complete LED luminaire or module powered through the connector.
Connector specifications focus on electrical and mechanical parameters. For a standard 4-pin connector used in commercial LED lighting systems, key technical attributes include a rated current capacity typically between 2A and 5A per pin depending on wire gauge and contact design, an operating temperature range of -25°C to +85°C, and voltage ratings commonly at 30V DC. Contact resistance is maintained below 20mΩ to minimize power loss and heat generation at the junction. The 4-pin configuration usually accommodates positive and negative DC power lines alongside two additional pins for dimming control signals, such as 0-10V or DALI protocols.
Beauty STC Manufacturing Co., Ltd. addresses the performance criteria you specified not through the connector itself, but through the integrated LED lighting systems where our connectors are implemented. Our engineered luminaires achieve lm/W efficacy exceeding 130 lm/W through high-efficiency drivers and premium LED chips. We consistently deliver CRI values greater than 90, often reaching Ra9 >50 for superior red spectrum rendering, using carefully selected phosphor blends in our LED packages. Complete luminaires incorporating Beauty STC connectors achieve IP65 or IP66 ratings through sealed housing designs and gasketed connector interfaces, not the connector alone. The connector’s role in this is critical for maintaining system integrity.
Beauty STC’s quality commitment ensures these connectors directly support high-performance lighting systems. We utilize phosphor bronze contacts with triple-layer gold plating (minimum 0.3μm) to prevent oxidation and maintain stable electrical conductivity over 5,000+ mating cycles. Our connectors undergo rigorous 100% automated contact resistance testing and 100% high-potential (hi-pot) testing at 1500V AC. The thermoplastic housings are UL94 V-0 rated and withstand 120 hours of 85°C/85% RH environmental stress testing. Precision molding ensures exact pin alignment, eliminating cross-mating risks. This manufacturing discipline prevents voltage drop, thermal runaway, and moisture ingress at the connection point—key factors in preserving the luminaire’s specified lm/W efficiency, color quality, and environmental protection throughout its service life. The connector is a reliability linchpin in our certified lighting solutions.

Application Scenarios
The 4-pin LED light connector serves a critical role in commercial lighting installations, particularly within constant voltage (typically 12V or 24V DC) flexible LED strip systems. Its primary function is to provide a secure, reliable, and often waterproof junction point between the power supply, the LED strip, and any required controllers or extension cables. Within hotels, malls, and offices, its application is most prevalent in specific architectural and functional lighting scenarios demanding modularity, ease of maintenance, and a clean aesthetic.
In hotels, 4-pin connectors are essential for recessed cove lighting in lobbies, corridors, and ballrooms where LED strips are mounted behind valances or within architectural reveals. They enable seamless connections around corners and facilitate future maintenance without dismantling entire runs. Guest room applications include under-bed lighting, vanity mirror perimeters, and headboard accents, where the connector’s secure lock prevents accidental disconnection during housekeeping or furniture movement. High-end suites often utilize them for custom millwork integrated lighting, ensuring reliable connections within cabinetry.
Malls heavily rely on 4-pin connectors for display case lighting within retail stores, providing a robust connection point that withstands frequent access for merchandise changes. They are equally vital for illuminated signage frames, channel letters, and perimeter ceiling coves in common areas, where vibration from foot traffic necessitates a connector resistant to loosening. Suspended ceiling soffits and feature walls in food courts or atriums also utilize these connectors for long, continuous runs requiring intermediate power injection points, maintaining consistent brightness across extensive installations.
Offices deploy 4-pin connectors extensively in suspended ceiling perimeter coves for indirect ambient lighting, allowing easy segmentation during office reconfigurations. Under-cabinet task lighting in kitchens, pantries, and reception desks benefits from the connector’s quick-disconnect capability for cleaning or adjustments. Modern partition walls with integrated lighting channels and stairwell step lighting also utilize these connectors, ensuring reliability in high-traffic zones where maintenance access must be swift and non-disruptive.
Installation demands strict adherence to best practices to ensure longevity and safety. Always verify the input voltage of the LED strip matches the power supply output before connecting; mismatched voltage (e.g., 12V strip to 24V supply) causes immediate and catastrophic failure. Observe polarity meticulously – reversing positive and negative leads at the connector will destroy the connected LED segment. Secure the connector housing firmly onto the strip’s contact pads until the locking mechanism audibly engages, then perform a gentle tug test to confirm. Implement proper strain relief on all wires entering the connector using cable ties or clamps to prevent mechanical stress on the solder joints. For any application in potentially damp locations like hotel pool areas, spa changing rooms, or exterior-facing mall entrances, exclusively use IP67 or IP68 rated 4-pin connectors and ensure the sealing gasket is fully seated and undamaged. Avoid exceeding the maximum current rating per connector; daisy-chaining multiple strips through a single connector often leads to overheating and connection failure – inject power at intervals as specified by the strip manufacturer. Finally, torque terminal screw connections to the manufacturer’s specification, typically 0.5-0.6 Nm, to prevent arcing or loosening over time. Always consult Beauty (STC) Manufacturing’s specific product documentation for connector compatibility and installation guidelines tailored to your project’s requirements.
