Technical Specs & Certifications
LED lighting that changes colors, commonly referred to as RGB or RGBW LED systems, delivers dynamic illumination through the combination of red, green, and blue diodes—with an optional white channel for improved color rendering and brightness. At Beauty (STC) Manufacturing Co., Ltd., our color-changing LED products are engineered to meet and exceed industry standards for performance, durability, and visual quality.
In terms of efficiency, our color-changing LED fixtures achieve a luminous efficacy ranging from 80 to 110 lumens per watt, depending on the configuration and color output. While full-spectrum white light typically delivers peak efficiency, even in dynamic color modes, our drivers and thermal management systems are optimized to maintain consistent lumen output across all hues. This ensures reliable performance without significant energy loss during color transitions.
Color quality is a key differentiator in our product line. While RGB systems traditionally struggle with accurate color rendering due to the absence of a broad spectral output, Beauty STC integrates high-CRI white LEDs (CRI >90) in our RGBW and tunable white fixtures. This hybrid approach allows users to switch between vibrant color effects and high-fidelity white lighting suitable for retail, hospitality, and architectural applications where accurate color representation is critical. Our phosphor-converted white LEDs are carefully selected to ensure R9 (saturated red) values exceed 50, contributing to a more natural and balanced light appearance.
Regarding environmental protection, Beauty STC offers color-changing LED solutions with IP ratings ranging from IP44 for indoor damp locations to IP65, IP66, and even IP67 for outdoor and harsh environments. Fixtures rated IP65 are dust-tight and protected against low-pressure water jets, making them ideal for exterior facades, landscape lighting, and poolside installations. Higher IP67-rated products are submersible up to 1 meter for 30 minutes, ensuring resilience in demanding conditions.
All Beauty STC LED lighting systems are built with high-quality drivers, precision optics, and robust aluminum or polycarbonate housings to ensure long service life—typically rated at L70 > 50,000 hours. Our manufacturing processes adhere to ISO 9001 standards, and every product undergoes rigorous photometric, thermal, and electrical testing. This commitment to quality ensures that our color-changing LED lights deliver not only vibrant visual effects but also reliable, efficient, and durable performance across diverse applications.
