Dorsan DS31 is a compact 15cm recessed downlight that redefines efficiency in small-form-factor lighting. Delivering 1,200 lumens from just 12 watts with an impressive 100 lm/W efficacy, this luminaire proves that great things come in small packages. Powered by genuine OSRAM chips and a flicker-free driver, it offers premium light quality where space is at a premium.
Weighing only 0.66 kg with a shallow 73mm depth, the DS31 is specifically designed for ceilings with limited clearance. The aluminum heat sink ensures effective thermal management, while the IP52 rating and 5-year warranty provide reliability in commercial and office environments with compact layouts.
Dorsan DS31 is the most compact member of Alton Ray’s professional recessed downlight family, featuring a 15cm diameter and 12W power consumption. Engineered for spaces where ceiling depth or diameter is restricted, this luminaire delivers the same technical excellence as its larger siblings in a space-saving format, without compromising on light quality or energy efficiency.
The primary challenge in small-diameter luminaires is achieving adequate luminous flux without increasing power density. The Dorsan DS31 overcomes this through high-density OSRAM LED chips and a precision flicker-free driver. With 1,200 lumens output at 12 watts and 100 lm/W efficacy, it achieves one of the highest efficiency ratings in its class. The CRI > 80 ensures accurate color rendering, making it suitable for retail displays, office workspaces, and commercial interiors where visual quality matters.
With a shallow profile of just 73mm, the DS31 is uniquely suited for suspended ceilings with limited plenum depth. The compact aluminum heat sink efficiently dissipates heat, maintaining operating temperatures within the –30°C to +50°C range and preserving LED longevity. The ABS+Aluminum hybrid body provides mechanical durability while keeping the total weight at 0.66 kg, simplifying installation in tight spaces.
Thanks to its small footprint and IP52 protection rating, the Dorsan DS31 is particularly well-suited for:
Narrow corridors and hallways with low ceiling clearance
Display cases and retail showcases
Renovation projects with limited ceiling depth
High-density commercial layouts such as chain stores and boutiques
The high-quality PP diffuser ensures smooth, uniform light distribution with a 100° beam angle, eliminating hot spots and reducing visual glare.
Available in three standard color temperatures, the DS31 adapts to various interior design requirements:
Warm White (3000K): Cozy, inviting atmospheres
Natural White (4000K): Productive office environments
Cool White (6500K): Bright, alert retail spaces
Each unit is supplied in an individual corrugated box, with master cartons containing 20 units at optimized dimensions of 40.7 × 38.8 × 40.1 cm – designed for efficient shipping and warehousing.
At Alton Ray, we believe that quality and efficiency should never be compromised by size. The Dorsan DS31 embodies this philosophy, combining premium components, professional engineering, and a 5-year warranty in a compact package. Whether for new construction or retrofit projects, the DS31 delivers reliable, energy-saving illumination where space is limited.
