Dorsan DS41 is a compact 20cm recessed LED downlight engineered by Alton Ray, delivering 16W of high-efficacy illumination. Powered by genuine OSRAM LED chips and a flicker-free driver, it produces 1,600 lumens with an outstanding 100 lumens per watt efficiency – making it a prime choice for energy-conscious commercial and office projects.
The ABS+Aluminum hybrid body weighs just 0.57 kg, reducing ceiling load while ensuring excellent heat dissipation across an operating range of –30°C to +50°C. With IP52 protection, a high-quality PP diffuser, and a 5-year manufacturer’s warranty, the Dorsan DS41 offers durability, uniform light distribution, and lasting reliability for specifiers and contractors alike.
Dorsan DS41 is a premium recessed LED downlight from Alton Ray‘s professional lighting portfolio, designed to meet the demands of modern office, commercial, and residential interiors. With a 20cm diameter and 16W power rating, this luminaire balances performance, energy savings, and aesthetic appeal, making it a trusted solution for construction and renovation projects of all scales.
Equipped with genuine OSRAM LED chips and a flicker-free (Free Flicker) driver, the Dorsan DS41 delivers stable, flicker-free illumination with minimal lumen depreciation over its lifetime. The high Color Rendering Index (CRI > 80) ensures accurate color reproduction, reducing visual fatigue and enhancing comfort in workspaces. With 1,600 lumens output and 100 lm/W efficacy, it achieves exceptional energy efficiency, directly lowering operational costs for large-scale installations.
Effective heat management is essential for LED longevity. The Dorsan DS41 incorporates a dedicated aluminum heat sink with optimized surface geometry, maintaining junction temperatures within the safe –30°C to +50°C operating range. This prevents thermal degradation and preserves light output over time. The ABS+Aluminum housing offers mechanical strength and impact resistance while keeping the total weight at just 0.57 kg – a critical advantage for suspended ceiling applications, reducing structural stress and simplifying handling.
Rated IP52, the Dorsan DS41 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 high-quality PP diffuser ensures smooth, glare-free light distribution with no hot spots, enhancing visual comfort across the illuminated area.
Available in three standard color temperatures, the Dorsan DS41 adapts to various design requirements:
Warm White (3000K): Ideal for hospitality, lounges, and residential spaces.
Natural White (4000K): Recommended for office environments and task-oriented workspaces.
Cool White (6500K): Suitable for retail areas, showrooms, and parking facilities.
Each unit is packed in a durable individual corrugated box to ensure product safety during transport and storage.
