Product Advantages of SL9250 Linear Lighting

The SL9250 Linear Lighting has several key product advantages that make it unique in the field of LED lighting:

  1. Energy efficient: The SL9250 consumes 50W of power and produces 5,000 lumens of luminous flux, which means that for every 1 watt of power consumed, it can produce 100 lumens of light. This is much more efficient than traditional lighting solutions. In addition, the SL9250 has a power factor of more than 0.9, meaning it minimizes the waste of power in converting electrical energy to light energy.
  1. Excellent light quality: The SL9250 has a color rendering index (CRI) of 83/90/95/Thrive, which means it can reproduce the color of objects very accurately. Higher CRI values mean truer, more natural colors. This is especially important for commercial lighting, as it can improve the attractiveness of merchandise and thus increase sales. In addition, the SL9250’s R9 index is greater than 50, which indicates excellent performance in reproducing red, an important component of human skin color, which is especially important for clothing, furniture and other situations where human skin color needs to be accurately displayed.
  1. Flexible installation and use: The SL9250 supports a variety of installation methods, including suspended, surface and rail mounting, which means it can be adapted to a variety of different interior spaces and design requirements. In addition, it supports Dali and thyristor dimming, allowing users to adjust the brightness and color of the light as needed to create the most ideal lighting environment.
  1. Outstanding durability and reliability:The SL9250’s housing is made of aluminium, iron and plastic with a fire rating of V2. The 6063 pure aluminium body design provides excellent heat dissipation, which is important for LED lights because overheating can reduce the life and luminous efficacy of LEDs. In addition, the SL9250 comes with a 5-year warranty and is CE, RoHS and FCC certified, which further proves its reliability.
  1. Personalized design: SL9250 is available in black, white and custom color options, which can meet the individual needs of different users. At the same time, its clean lines and modern design can be integrated into various interior design styles to enhance the aesthetics of the space.
