Donya DN11 is the smallest and most energy-efficient recessed downlight in the Alton Ray portfolio, featuring an ultra-compact 8cm diameter and just 5W power consumption. This micro-luminaire delivers 450 lumens with 90 lm/W efficacy using reliable EPISTAR LED chips, making it the ultimate cost-effective solution for massive-scale residential and office projects where budget optimization and high unit counts are paramount. The wide 120° beam angle ensures adequate light distribution in very small spaces and tight corners.
At just 0.14 kg with a minimal 39mm depth, the DN11 minimizes suspended ceiling load and simplifies installation in developments with thousands of units. The electrostatic powder coating provides enhanced corrosion and wear resistance, while the IP52 protection rating and 3-year warranty deliver dependable performance in compact residential and office environments. With 54 units per master carton – the highest density in the Donya family – the DN11 offers exceptional logistics efficiency for large-scale projects.
Donya DN11 is the most compact member of Alton Ray’s economy recessed downlight family, featuring an ultra-small 8cm diameter and 5W power consumption. Specifically engineered for massive-scale residential and office developments with exceptionally high unit counts and tightly controlled budgets, this micro-luminaire delivers professional-grade basic illumination in the smallest possible form factor. It represents the ultimate practical solution for developers, contractors, and government projects requiring reliable lighting across thousands of units without compromising on cost efficiency.
The DN11 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 in the smallest possible package. These high-density chips generate 450 lumens at just 5 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 very small rooms, tight corners, and narrow passages where standard-sized fixtures would be impractical.
Weighing just 0.14 kg, the DN11 is the lightest recessed downlight in the entire Alton Ray portfolio – a remarkable achievement for a fully enclosed luminaire with thermal management. This ultra-lightweight construction provides significant advantages for mega-scale projects:
Minimal load on suspended ceiling systems across thousands of installations
Dramatically reduced shipping and logistics costs per unit
Faster and easier handling by installation crews
Lower risk of ceiling damage during installation
The minimal 39mm depth enables installation in ceilings with extremely limited plenum space, making the DN11 suitable for even the most challenging retrofit projects. The integrated aluminum heat sink, despite its micro-scale design, effectively manages thermal dissipation across the –30°C to +50°C operating range, preserving LED longevity and maintaining consistent light output.
A distinctive feature of the DN11 is its electrostatic powder coating finish – a premium surface treatment that significantly enhances resistance to corrosion, abrasion, and environmental factors. This coating, typically reserved for higher-end products, ensures exceptional durability and long-term aesthetic retention even in demanding environments. The high-quality PS diffuser provides smooth, glare-free light distribution across the wide 120° beam angle, ensuring visual comfort in compact spaces.
With its miniature dimensions, IP52 protection rating, and enhanced surface treatment, the DN11 is particularly well-suited for:
Mega-scale residential developments with thousands of apartment units
Large office complexes with high numbers of small rooms and cubicles
Narrow corridors and passageways with standard ceiling heights
Retrofit projects with extreme limitations on ceiling cavity depth
Small service spaces such as storage rooms, closets, and utility areas
Government and public housing projects with strict budget constraints
Available in three standard color temperatures, the DN11 accommodates various interior design preferences and functional requirements:
Warm White (3000K): Creates cozy, inviting atmospheres in compact residential spaces
Natural White (4000K): Enhances focus and clarity in office and work environments
Cool White (6500K): Provides bright, alert illumination for corridors and service areas
Each unit is supplied in an individual corrugated box, with master cartons containing 54 units – the highest density in the Donya family – at optimized dimensions of 45 × 43.6 × 30 cm. This maximum-density packaging delivers exceptional logistics efficiency:
Significantly reduced storage space requirements per unit
Minimum shipping costs per fixture
Faster handling and warehouse throughput
Reduced carbon footprint per unit transported
For projects requiring thousands of units, these logistics advantages translate into substantial cost savings.
