Large LED Downlights Recessed for Big Diamemter Hole with Modular Design

ILED-DL-B T2 series of Large LED Downlights stands out in the realm of recessed lighting, specifically tailored for installations requiring substantial cutout diameters, where traditional fixtures often fall short in coverage and compatibility. This modular design innovation—sharing a single, high-performance heatsink module across all sizes—streamlines inventory management, reduces installation complexity, and ensures consistent thermal dissipation for prolonged LED lifespan. Available in four versatile models, each spanning 15W to 35W power ratings and delivering 2000 to 4000 lumens at an impressive 120LM/W efficiency, these downlights illuminate vast areas with minimal energy draw. The compact profiles—φ195x51mm with φ165-180mm cutout for the DL6, φ230x51mm with φ200-220mm for DL8, φ285x60mm with φ245-270mm for DL10, and φ305x69mm with φ270-290mm for DL12—make them perfect for retrofitting oversized holes in commercial ceilings without extensive structural modifications. Input compatibility spans 220-240VAC or 110-277VAC, accommodating global standards, while the Class II electrical classification and power factor over 0.9 promote safe, stable operation free from voltage fluctuations. Crafted from premium aluminum housings paired with durable PC optics, the ILED-DL-B T2 offers robust construction in sleek white or black finishes that blend seamlessly into contemporary architectures. IP20 rating suits standard indoor environments, but the optional IP54 upgrade provides dust and moisture resistance for humid or dusty applications like corridors or workshops. At the core are LM80-certified LEDs, validated for exceptional durability and light output retention over 50,000 hours, coupled with high CRI performance: 90 for premium color fidelity in detail-oriented spaces or 80 (minimum >82) for versatile general use. This ensures that reds, blues, and neutrals render true, enhancing visual appeal in everything from product showcases to living areas. The wide 120° beam angle, combined with precise optics, creates broad, even illumination without dark spots, fostering an open, inviting atmosphere. Customization is a hallmark, with 3CCT selectable temperatures—warm 3000K for relaxation, neutral 4000K for clarity, and cool 6000K for alertness—adjustable on-site to evolve with space functions. Advanced control options elevate usability: DALI for networked, programmable scenes in smart buildings; Triac for effortless pairing with household dimmers; 0-10V for fine-tuned analog adjustments; and integrated emergency lighting for uninterrupted safety during outages. These features not only comply with stringent codes but also support dynamic lighting strategies, such as circadian rhythm alignment in offices or accent shifts in retail. The modular heatsink, a game-changer, dissipates heat efficiently across models, preventing hotspots and extending component life, which is backed by a generous 3-5 year warranty against defects. Certifications including SAA for Australian safety, CE for European conformity, and ROHS for environmental compliance underscore the series’ global readiness, assuring installers of hassle-free approvals. Beyond performance, the ILED-DL-B T2 prioritizes sustainability: its high efficacy slashes energy costs by up to 50% versus halogens, and recyclable materials align with eco-friendly initiatives. For contractors, the shared modular components mean fewer parts to stock, faster deployments, and lower long-term ownership expenses. In high-ceiling venues like atriums or warehouses, the large cutouts allow for fewer fixtures to achieve desired lux levels, optimizing aesthetics and budgets. Ultimately, this series transforms challenging large-hole recessing into an opportunity for superior, adaptable lighting that marries form, function, and future-proofing in one elegant package.
