Donya DN31 is a 15cm recessed LED downlight engineered for residential projects where cost-efficiency and reliable performance are equally important. Powered by EPISTAR LED chips and delivering 1,080 lumens at just 12 watts with 90 lm/W efficacy, this luminaire offers a balanced lighting solution for apartment complexes, corridors, and public spaces. Its wide 120° beam angle ensures even light distribution across standard-height ceilings.
With a lightweight 0.42 kg ABS+Aluminum body and a shallow 52mm profile, the DN31 minimizes ceiling load and fits easily into tight plenum spaces. The aluminum heat sink provides adequate thermal management across the –30°C to +50°C operating range, while the IP52 protection rating and 3-year warranty make it a dependable choice for cost-conscious residential developments.
Donya DN31 is a value-engineered recessed downlight from Alton Ray, specifically developed for large-scale residential projects where budget optimization is a primary consideration without compromising on basic lighting quality. With a 15cm diameter and 12W power consumption, this luminaire addresses the needs of apartment buildings, residential corridors, and common areas, offering a practical balance between initial cost and long-term reliability.
At the core of the DN31 are EPISTAR LED chips, sourced from one of Taiwan’s leading semiconductor manufacturers. These chips provide a proven balance of performance and cost-effectiveness, delivering 1,080 lumens of luminous flux with 90 lumens per watt efficacy. The Color Rendering Index (CRI > 80) ensures natural color reproduction, creating comfortable visual environments for residents and visitors alike. The 120° wide beam angle guarantees uniform illumination across standard residential spaces, minimizing dark spots and reducing the number of fixtures required per area.
Weighing just 0.42 kg, the DN31 is one of the lightest fixtures in its class – a significant advantage for suspended ceiling installations where structural load must be carefully managed. The shallow 52mm depth allows installation in ceilings with limited plenum clearance, making it suitable for both new construction and retrofit projects. The integrated aluminum heat sink effectively dissipates heat, maintaining junction temperatures within the –30°C to +50°C safe operating range and preserving LED lifespan. The ABS+Aluminum hybrid housing provides mechanical durability while keeping weight to an absolute minimum.
With its IP52 ingress protection rating, the DN31 offers reliable performance in residential environments where dust and occasional moisture are present. Its key applications include:
Multi-story apartment complexes requiring hundreds of units with consistent quality
Building corridors and hallways with standard ceiling heights
Parking areas and storage rooms within residential developments
Renovation projects where cost control is a primary concern
The high-quality PP diffuser ensures smooth, glare-free light distribution across the wide 120° beam angle, enhancing visual comfort in everyday living spaces.
Available in three standard color temperatures, the DN31 adapts to various residential design preferences:
Warm White (3000K): Creates inviting, cozy atmospheres for living rooms and bedrooms
Natural White (4000K): Ideal for study areas, kitchens, and task-oriented spaces
Cool White (6500K): Suitable for utility areas, garages, and high-traffic corridors
Each unit is supplied in an individual corrugated box, with master cartons containing 24 units at dimensions of 40.7 × 38.8 × 40.1 cm. This optimized packaging density reduces shipping costs and storage footprint – a critical consideration for large-scale residential developments with high fixture counts.
At Alton Ray, we understand that residential developers require lighting solutions that balance quality, reliability, and cost. The Donya DN31 embodies this philosophy, offering professional-grade illumination at an accessible price point. Backed by a 3-year warranty and our nationwide technical support network, the DN31 is a dependable choice for projects where value and performance must coexist.
