Core Technology & Optical Performance<\/span><\/h3>\n

At the heart of the Darsan DS51 lies\u00a0<\/span>genuine OSRAM LED chips<\/span><\/strong>\u00a0\u2013 a mark of superior light quality and long-term color consistency. Paired with a\u00a0<\/span>flicker-free (Free Flicker) driver<\/span><\/strong>, the fixture ensures stable, glare-free light output that minimizes eye strain and fatigue during extended working hours. With a\u00a0<\/span>Color Rendering Index (CRI) > 80<\/span><\/strong>, the DS51 reproduces colors naturally and vividly, making it an ideal choice for retail displays, showrooms, and professional office spaces where visual accuracy matters.<\/span><\/p>\n

Offering\u00a0<\/span>2,100 lumens<\/span><\/strong>\u00a0of luminous flux at just\u00a0<\/span>22 watts<\/span><\/strong>\u00a0of power consumption, the unit achieves an outstanding\u00a0<\/span>efficacy of 95 lumens per watt<\/span><\/strong>. This exceptional efficiency translates directly into lower energy bills and reduced carbon footprint, particularly in projects with hundreds of installed units.<\/span><\/p>\n

\n

Thermal Management & Structural Integrity<\/span><\/h3>\n

Effective heat dissipation is critical to LED longevity. The Darsan DS51 features a dedicated\u00a0<\/span>aluminum heat sink<\/span><\/strong>\u00a0with optimized surface area that maintains junction temperatures within the safe operating range of\u00a0<\/span>\u201330\u00b0C to +50\u00b0C<\/span><\/strong>, preventing premature lumen depreciation and ensuring stable performance over the product’s lifetime.<\/span><\/p>\n

The housing combines\u00a0<\/span>impact-resistant ABS<\/span><\/strong>\u00a0with an aluminum core, offering robust mechanical protection while keeping the total weight at just\u00a0<\/span>1 kg<\/span><\/strong>\u00a0\u2013 a significant advantage for suspended ceiling installations, reducing structural load and simplifying handling during installation.<\/span><\/p>\n

\n

Environmental Protection & Installation Convenience<\/span><\/h3>\n

With an ingress protection rating of\u00a0<\/span>IP52<\/span><\/strong>, the DS51 is well-protected against dust ingress and vertical water drips, making it suitable for semi-humid environments such as commercial kitchens, covered walkways, and high-traffic corridors. The fixture comes equipped with a\u00a0<\/span>pre-wired plug (connector)<\/span><\/strong>\u00a0, which streamlines on-site electrical connections, minimizes wiring errors, and accelerates installation timelines \u2013 a feature highly valued by contractors managing tight project schedules.<\/span><\/p>\n

\n

Versatile Color Temperature Options<\/span><\/h3>\n

Recognizing that different spaces demand different lighting atmospheres, the Darsan DS51 is available in\u00a0<\/span>three standard color temperatures<\/span><\/strong>:<\/span><\/p>\n

    \n
  • \n

    Warm White (3000K):<\/span><\/strong>\u00a0Ideal for hospitality, lounges, and residential interiors.<\/span><\/p>\n<\/li>\n

  • \n

    Natural White (4000K):<\/span><\/strong>\u00a0The recommended choice for offices, schools, and workspaces requiring alertness and focus.<\/span><\/p>\n<\/li>\n

  • \n

    Cool White (6500K):<\/span><\/strong>\u00a0Suited for commercial areas, parking garages, and industrial zones where high visibility is essential.<\/span><\/p>\n<\/li>\n<\/ul>\n

    \n

    Packaging & Logistics<\/span><\/h3>\n

    Each unit is packed in a sturdy individual\u00a0<\/span>corrugated cardboard box<\/span><\/strong>\u00a0to ensure safe transport and easy warehousing. Master cartons accommodate\u00a0<\/span>20 units<\/span><\/strong>\u00a0per box, with compact dimensions of\u00a0<\/span>51.6 \u00d7 53.5 \u00d7 47.4 cm<\/span><\/strong>, enabling efficient containerization and cost-effective shipping for international orders.<\/span><\/p>\n
