Technical Specs & Certifications
Diffusing LED light strips are engineered to deliver uniform, glare-free illumination by incorporating a milky white or frosted silicone or PVC cover over the LED array. This diffusion layer effectively blends individual LED points into a continuous line of light, making them ideal for architectural accenting, cove lighting, under-cabinet installations, and retail displays where visual comfort and aesthetic appeal are critical.
In terms of performance, high-quality diffusing LED light strips from Beauty (STC) Manufacturing Co., Ltd. achieve luminous efficacies ranging from 100 to 130 lumens per watt, depending on the LED density and binning. This efficiency is attained through the use of premium 2835 or 5050 SMD LEDs paired with optimized driver configurations and thermally efficient flexible PCBs. These values place Beauty STC’s strips at the higher end of the market spectrum, ensuring energy savings without sacrificing brightness.
Color Rendering Index (CRI) is a key focus for applications requiring accurate color representation. Beauty STC’s diffusing LED strips consistently achieve a CRI greater than 90, with Ra values typically between 92 and 95. This is accomplished using high-CRI LED chips and phosphor coatings that enhance spectral distribution across the visible spectrum. As a result, illuminated surfaces appear more natural and vibrant, making these strips suitable for museums, retail environments, and high-end residential projects.
