Technical Specs & Certifications
A 4000K LED light refers to a neutral white LED with a correlated color temperature of 4000 kelvins, offering balanced illumination suitable for commercial, industrial, and high-end residential environments. When evaluating high-performance 4000K LED lighting solutions, particularly those manufactured by Beauty (STC) Manufacturing Co., Ltd., several key technical specifications define product quality and efficiency.
Lumens per watt (lm/W) is a critical measure of energy efficiency, indicating how much visible light is produced per unit of electrical power consumed. At Beauty STC, our 4000K LED lights typically achieve luminous efficacy in the range of 130 to 160 lumens per watt, depending on the fixture type and thermal design. This high efficiency is achieved through advanced chip-on-board (COB) and mid-power SMD LED technologies, precision optical design, and high-efficiency constant-current drivers that minimize energy loss.
Color Rendering Index (CRI) is another essential specification, especially in applications where accurate color representation is vital, such as retail, healthcare, and design studios. Beauty STC ensures that our 4000K LED products consistently deliver a CRI greater than 90, with some premium lines reaching Ra >95. This is accomplished by using phosphor-converted LEDs with tightly controlled spectral distribution and rigorous binning processes during manufacturing to maintain color consistency across batches.
Ingress Protection (IP) ratings define a fixture’s resistance to dust and moisture, which is crucial for durability in challenging environments. Beauty STC offers 4000K LED lights across a wide range of IP ratings to suit diverse applications. For indoor commercial use, fixtures typically carry an IP40 or IP42 rating, providing protection against solid objects and limited moisture. For outdoor, industrial, or washdown environments, our products are available with IP65, IP66, and even IP67 ratings, ensuring complete dust tightness and resistance to water jets or temporary submersion. These ratings are achieved through robust die-cast aluminum housings, silicone gaskets, and conformal-coated electronic components.
Quality is at the core of Beauty STC’s manufacturing philosophy. Our 4000K LED lights undergo rigorous testing for thermal management, lumen maintenance (L70/L90), surge protection (up to 10kV), and photobiological safety (IEC 62471). We adhere to international standards including UL, CE, RoHS, and ERP, and our production facilities follow ISO 9001-certified quality management systems. The result is a reliable, long-life lighting solution—typically rated for 50,000 to 100,000 hours—backed by comprehensive warranties and consistent photometric performance over time.
In summary, Beauty STC’s 4000K LED lights combine high luminous efficacy (130–160 lm/W), excellent color rendering (CRI >90), and versatile IP protection (up to IP67), all engineered to deliver superior optical performance, energy savings, and long-term reliability across a broad range of applications.
Factory Tour: Manufacturing Excellence
Beauty STC operates a modern, ISO 9001 and ISO 14001 certified LED lighting manufacturing facility in Jiangmen, Guangdong Province. This strategic location leverages the robust Pearl River Delta supply chain while providing ample space for integrated production. The factory encompasses dedicated cleanroom areas for Surface Mount Technology assembly, comprehensive optical and electrical testing laboratories, and climate-controlled aging chambers, all supporting high-volume, precision manufacturing.
