Technical Specs & Certifications

It is important to clarify a fundamental technical point regarding your query. An LED connector to 4-pin wire is a passive electrical component, not a light source. Therefore, it does not possess inherent lumens per watt (lm/W) efficiency or Color Rendering Index (CRI) values. Lumens per watt and CRI are specifications exclusively tied to the active LED light engine or module that the connector supplies power to. The connector’s role is to reliably transmit electrical current from a driver to the LED module. Similarly, IP (Ingress Protection) ratings apply to the complete luminaire or the specific sealed section where the connector is installed, not the bare connector component itself prior to integration.

For Beauty STC’s standard 4-pin LED connectors, such as our widely used STC-4P series, the relevant electrical and mechanical specifications focus on enabling high-performance lighting systems. These connectors typically support a maximum continuous current of 3.0A per pin at 60°C ambient, with a voltage rating of 30V DC. They are constructed using high-temperature resistant PA66 or PBT thermoplastic housings meeting UL94 V-0 flammability standards, paired with precision phosphor bronze or beryllium copper contacts featuring gold or tin plating for low contact resistance and long-term corrosion resistance. Key performance characteristics ensuring system reliability include an operating temperature range of -40°C to +105°C and mating durability exceeding 500 cycles. Beauty STC rigorously tests these connectors for contact resistance stability, insulation resistance, and dielectric strength to exceed IEC 60512 standards.

While the connector itself does not generate light, Beauty STC designs and manufactures complete LED lighting systems where our 4-pin connectors are integral. In these systems, we consistently achieve luminous efficacies exceeding 130 lm/W for standard products and surpass 150 lm/W in high-efficiency lines, utilizing premium LED chips from partners like Samsung and Lumileds. Crucially, all Beauty STC architectural and retail lighting products targeting color-critical applications maintain a minimum CRI of Ra >90, with many achieving Ra >95 and R9 >50 for exceptional red rendering, verified through third-party LM-79 testing. Regarding environmental protection, our luminaires incorporating these 4-pin connectors are engineered to specific IP ratings. Common configurations include IP65 for outdoor wall washers and IP67 for landscape lighting, achieved through integrated silicone gasketing within the connector assembly and fixture housing during manufacturing. Each sealed connector undergoes stringent IP verification testing per IEC 60529 using calibrated pressure differentials and water ingress protocols.

Beauty STC’s commitment to quality is embedded in every stage of connector and luminaire production. Our Ningbo manufacturing facility implements a zero-defect philosophy with 100% automated contact resistance testing on every connector pair and 100% high-potential dielectric testing. We utilize SPC (Statistical Process Control) monitoring for critical dimensions and material properties, with raw materials subjected to rigorous incoming inspection including UL E363029 file compliance verification. This disciplined approach ensures our connectors provide the stable, low-loss power delivery necessary for our LED systems to consistently meet and exceed high lm/W, >90 CRI, and robust IP rating requirements demanded by global architectural and commercial projects. The reliability of our connectors directly contributes to the long-term photometric performance and environmental resilience of the final lighting product.

Application Scenarios

LED connectors to 4-pin wire are primarily used in advanced LED lighting systems requiring independent control of multiple color channels or white light temperature tuning. Their application in hotels, malls, and offices centers around dynamic or human-centric lighting scenarios where standard single-color or basic RGB systems are insufficient. In hotel lobbies and high-end guest corridors, these connectors enable tunable white systems that shift from warm 2700K to cool 4000K light to align with circadian rhythms or time of day, enhancing guest experience without visible wiring clutter. Luxury hotel ballrooms and executive lounges utilize them for RGBW (Red, Green, Blue, White) installations where pure white light is needed alongside full-color capabilities for events, with the fourth pin dedicated to the white channel for brighter, cleaner whites than RGB mixing can achieve. Shopping malls deploy these connectors extensively in feature ceilings, architectural coves, and digital signage backlights where RGBW systems create vibrant brand-aligned color washes while maintaining high-quality white illumination for merchandise visibility. Office environments implement them in conference rooms with tunable white systems allowing presenters to adjust light temperature from collaborative warm tones to focused cool tones, and in open-plan workspaces where circadian lighting supports productivity through gradual daylight-mimicking shifts.

Critical installation practices begin with verifying the specific pinout configuration against the manufacturer’s datasheet since pin assignments vary significantly—common configurations include RGBW (positive common with separate R/G/B/W channels) or tunable white (positive common with 2700K/6500K channels). Never assume standardization as reversed polarity can instantly damage LEDs. Always strip wires precisely to manufacturer specifications, typically 3-5mm, and use crimp connectors with insulated sleeves rather than soldering to prevent cold joints or insulation damage during insertion. Apply strain relief within 50mm of the connector using cable ties to fixtures or mounting surfaces to avoid wire pull-out from vibration or accidental tugging, particularly crucial in high-traffic mall corridors or hotel service areas. For tunable white systems in offices, meticulously label both ends of all four conductors during pull-through to prevent channel swapping that would disrupt correlated color temperature (CCT) control. Seal outdoor-rated or damp-location connectors (e.g., pool areas in luxury hotels) with dielectric grease before mating to prevent moisture ingress, even if the fixture claims IP65 rating. Finally, conduct a full system test with the controller before final mounting—temporarily power the circuit and verify all channels respond correctly to avoid costly rework after ceiling access panels are closed in office drop ceilings or mall soffits. Never force connectors; if resistance is felt, recheck alignment as mis-mating causes pin bending and intermittent failures.
