Darsan DS51 is a high-performance recessed LED downlight engineered and manufactured by Alton Ray, a leading Iranian lighting manufacturer with a commitment to international quality standards. Developed for professional applications in commercial, office, and residential environments, this luminaire combines premium-grade materials, advanced thermal management, and energy-efficient optics to deliver reliable, long-lasting illumination for large-scale construction and renovation projects.
At the heart of the Darsan DS51 lies genuine OSRAM LED chips – a mark of superior light quality and long-term color consistency. Paired with a flicker-free (Free Flicker) driver, the fixture ensures stable, glare-free light output that minimizes eye strain and fatigue during extended working hours. With a Color Rendering Index (CRI) > 80, the DS51 reproduces colors naturally and vividly, making it an ideal choice for retail displays, showrooms, and professional office spaces where visual accuracy matters.
Offering 2,100 lumens of luminous flux at just 22 watts of power consumption, the unit achieves an outstanding efficacy of 95 lumens per watt. This exceptional efficiency translates directly into lower energy bills and reduced carbon footprint, particularly in projects with hundreds of installed units.
Effective heat dissipation is critical to LED longevity. The Darsan DS51 features a dedicated aluminum heat sink with optimized surface area that maintains junction temperatures within the safe operating range of –30°C to +50°C, preventing premature lumen depreciation and ensuring stable performance over the product’s lifetime.
The housing combines impact-resistant ABS with an aluminum core, offering robust mechanical protection while keeping the total weight at just 1 kg – a significant advantage for suspended ceiling installations, reducing structural load and simplifying handling during installation.
With an ingress protection rating of IP52, 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 pre-wired plug (connector) , which streamlines on-site electrical connections, minimizes wiring errors, and accelerates installation timelines – a feature highly valued by contractors managing tight project schedules.
Recognizing that different spaces demand different lighting atmospheres, the Darsan DS51 is available in three standard color temperatures:
Warm White (3000K): Ideal for hospitality, lounges, and residential interiors.
Natural White (4000K): The recommended choice for offices, schools, and workspaces requiring alertness and focus.
Cool White (6500K): Suited for commercial areas, parking garages, and industrial zones where high visibility is essential.
Each unit is packed in a sturdy individual corrugated cardboard box to ensure safe transport and easy warehousing. Master cartons accommodate 20 units per box, with compact dimensions of 51.6 × 53.5 × 47.4 cm, enabling efficient containerization and cost-effective shipping for international orders.
