Donya DN21 is the smallest member of Alton Ray’s value-engineered downlight family, featuring a 12cm diameter and 9W power consumption. This ultra-compact luminaire delivers 810 lumens with 90 lm/W efficacy using reliable EPISTAR LED chips, making it an ideal solution for large-scale residential projects where budget optimization and high unit counts are critical priorities. The wide 120° beam angle ensures even light distribution in compact spaces and narrow corridors.
At just 0.27 kg with a shallow 52mm profile, the DN21 minimizes suspended ceiling load and simplifies installation in high-volume developments. The IP52 protection rating and 3-year warranty provide dependable performance in apartment complexes, residential corridors, and common areas where reliable basic illumination is essential.
Donya DN21 is the most compact member of Alton Ray’s economy recessed downlight family, featuring a 12cm diameter and 9W power consumption. Specifically developed for large-scale residential projects with high unit counts and controlled budgets, this luminaire delivers professional-grade basic illumination in a miniaturized form factor. It represents a practical solution for developers and contractors who require reliable lighting across hundreds of units without compromising on cost efficiency.
The DN21 is powered by EPISTAR LED chips – sourced from one of Taiwan’s most respected semiconductor manufacturers – which achieve an optimal balance between cost and performance. These high-density chips generate 810 lumens at just 9 watts with an impressive 90 lumens per watt efficacy for this product category. The Color Rendering Index (CRI > 80) ensures natural color appearance, while the 120° wide beam angle provides uniform light distribution across small rooms, narrow hallways, and compact residential spaces, minimizing shadow zones and dark corners.
Weighing just 0.27 kg, the DN21 is the lightest recessed downlight in the Alton Ray portfolio. This ultra-lightweight construction directly translates into significant advantages for large-scale projects:
Reduced load on suspended ceiling systems across hundreds of installations
Lower shipping and logistics costs per unit
Simplified handling and faster installation by electrical contractors
The shallow 52mm profile enables installation in ceilings with limited plenum space, making the DN21 suitable for both new construction and retrofit projects. The integrated aluminum heat sink, despite its compact size, effectively manages thermal dissipation across the –30°C to +50°C operating range, preserving LED longevity and maintaining consistent light output. The ABS+Aluminum hybrid housing provides mechanical durability while keeping weight to an absolute minimum.
With its IP52 protection rating and compact dimensions, the DN21 is particularly well-suited for:
Small-footprint apartments and studio units requiring basic ambient lighting
Narrow corridors and hallways in multi-story residential buildings
High-volume housing developments with cost-optimized specifications
Residential parking areas and storage rooms
Retrofit projects with limited ceiling cavity depth
The high-quality PP diffuser ensures smooth, glare-free light distribution across the 120° beam angle, enhancing visual comfort in everyday living and transit spaces.
Available in three standard color temperatures, the DN21 accommodates various interior design preferences and functional requirements:
Warm White (3000K): Creates cozy, inviting atmospheres in living rooms and bedrooms
Natural White (4000K): Enhances focus and clarity in kitchens, studies, and workspaces
Cool White (6500K): Provides bright, alert illumination for corridors, parking areas, and utility spaces
Each unit is supplied in an individual corrugated box, with master cartons containing 32 units at optimized dimensions of 50 × 34.6 × 38.5 cm. This high-density packaging significantly reduces storage space requirements and shipping costs per unit – a critical economic advantage for large-scale residential projects requiring thousands of fixtures.
At Alton Ray, we understand the unique challenges of large-scale residential developments – where quality, reliability, and cost must be carefully balanced. The Donya DN21 embodies this philosophy, offering professional-grade illumination in a cost-effective, ultra-compact package. Backed by a 3-year warranty and our nationwide technical support network, the DN21 is a dependable choice for developers and contractors who demand value without compromising on basic quality.
Choosing the Donya DN21 means selecting a practical, high-density lighting solution – engineered for residential environments, built with reliable components, and supported by a manufacturer committed to customer satisfaction.
