Donya DN21<\/span><\/strong>\u00a0is 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.<\/span><\/p>\n

Optimized Optical Performance in a Miniature Package<\/span><\/h4>\n

The DN21 is powered by\u00a0<\/span>EPISTAR<\/span><\/strong>\u00a0LED chips \u2013 sourced from one of Taiwan’s most respected semiconductor manufacturers \u2013 which achieve an optimal balance between cost and performance. These high-density chips generate\u00a0<\/span>810 lumens<\/span><\/strong>\u00a0at just\u00a0<\/span>9 watts<\/span><\/strong>\u00a0with an impressive\u00a0<\/span>90 lumens per watt<\/span><\/strong>\u00a0efficacy for this product category. The\u00a0<\/span>Color Rendering Index (CRI > 80)<\/span><\/strong>\u00a0ensures natural color appearance, while the\u00a0<\/span>120\u00b0<\/span><\/strong>\u00a0wide beam angle provides uniform light distribution across small rooms, narrow hallways, and compact residential spaces, minimizing shadow zones and dark corners.<\/span><\/p>\n

Ultra-Lightweight Design for High-Volume Construction<\/span><\/h4>\n

Weighing just\u00a0<\/span>0.27 kg<\/span><\/strong>, 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:<\/span><\/p>\n

    \n
  • \n

    Reduced load on suspended ceiling systems across hundreds of installations<\/span><\/p>\n<\/li>\n

  • \n

    Lower shipping and logistics costs per unit<\/span><\/p>\n<\/li>\n

  • \n

    Simplified handling and faster installation by electrical contractors<\/span><\/p>\n<\/li>\n<\/ul>\n

    The shallow\u00a0<\/span>52mm<\/span><\/strong>\u00a0profile enables installation in ceilings with limited plenum space, making the DN21 suitable for both new construction and retrofit projects. The integrated\u00a0<\/span>aluminum heat sink<\/span><\/strong>, despite its compact size, effectively manages thermal dissipation across the\u00a0<\/span>\u201330\u00b0C to +50\u00b0C<\/span><\/strong>\u00a0operating range, preserving LED longevity and maintaining consistent light output. The\u00a0<\/span>ABS+Aluminum<\/span><\/strong>\u00a0hybrid housing provides mechanical durability while keeping weight to an absolute minimum.<\/span><\/p>\n

    Ideal Applications for Compact Residential Spaces<\/span><\/h4>\n

    With its\u00a0<\/span>IP52<\/span><\/strong>\u00a0protection rating and compact dimensions, the DN21 is particularly well-suited for:<\/span><\/p>\n

      \n
    • \n

      Small-footprint apartments and studio units<\/span><\/strong>\u00a0requiring basic ambient lighting<\/span><\/p>\n<\/li>\n

    • \n

      Narrow corridors and hallways<\/span><\/strong>\u00a0in multi-story residential buildings<\/span><\/p>\n<\/li>\n

    • \n

      High-volume housing developments<\/span><\/strong>\u00a0with cost-optimized specifications<\/span><\/p>\n<\/li>\n

    • \n

      Residential parking areas and storage rooms<\/span><\/strong><\/p>\n<\/li>\n

    • \n

      Retrofit projects<\/span><\/strong>\u00a0with limited ceiling cavity depth<\/span><\/p>\n<\/li>\n<\/ul>\n

      The high-quality\u00a0<\/span>PP diffuser<\/span><\/strong>\u00a0ensures smooth, glare-free light distribution across the 120\u00b0 beam angle, enhancing visual comfort in everyday living and transit spaces.<\/span><\/p>\n

      Flexible Color Temperature Selection<\/span><\/h4>\n

      Available in\u00a0<\/span>three standard color temperatures<\/span><\/strong>, the DN21 accommodates various interior design preferences and functional requirements:<\/span><\/p>\n

        \n
      • \n

        Warm White (3000K):<\/span><\/strong>\u00a0Creates cozy, inviting atmospheres in living rooms and bedrooms<\/span><\/p>\n<\/li>\n

      • \n

        Natural White (4000K):<\/span><\/strong>\u00a0Enhances focus and clarity in kitchens, studies, and workspaces<\/span><\/p>\n<\/li>\n

      • \n

        Cool White (6500K):<\/span><\/strong>\u00a0Provides bright, alert illumination for corridors, parking areas, and utility spaces<\/span><\/p>\n<\/li>\n<\/ul>\n

        High-Density Packaging for Cost-Efficient Distribution<\/span><\/h4>\n

        Each unit is supplied in an individual\u00a0<\/span>corrugated box<\/span><\/strong>, with master cartons containing\u00a0<\/span>32 units<\/span><\/strong>\u00a0at optimized dimensions of\u00a0<\/span>50 \u00d7 34.6 \u00d7 38.5 cm<\/span><\/strong>. This high-density packaging significantly reduces storage space requirements and shipping costs per unit \u2013 a critical economic advantage for large-scale residential projects requiring thousands of fixtures.<\/span><\/p>\n
