Large 500mm 800mm 1000mm Round LED Oyster Ceiling light Emergency Sensor DALI

The Large 500mm/800mm/1000mm Round LED Oyster Ceiling Light, model ILED-OL-B24W(500/800/1000), is a powerhouse of scalable, feature-rich illumination designed to dominate expansive interiors with its oversized, surface-mounted round profile, serving as a superior upgrade from conventional 2D fluorescent fittings in commercial and institutional settings. This series extends across three flagship sizes—500mm (36W, D500x120mm, 2880LM), 800mm (50W, D800x170mm, 4000LM), and 1000mm (60W, D1000x250mm, 4800LM)—all achieving a robust 100LM/W efficacy through high-quality LumiLEDs 2835 LEDs, which deliver exceptional color rendering (CRI >83) and tunable CCT from 2800K warm white to 7000K cool daylight, ensuring vibrant, natural light that adapts to any ambiance or task demand. The iron housing, finished in a clean white paint for timeless appeal, encases a premium PMMA diffuser that scatters light softly across a 120° beam angle, creating uniform, glare-free coverage that spans up to 50 sqm in the largest model, transforming vast lobbies or warehouses into welcoming, efficient havens without dark spots or harsh contrasts. Versatility is at the forefront, with optional dimming protocols—DALI for intelligent, addressable control in networked systems; Triac for straightforward wall-switch integration; and 0-10V for analog precision—enabling seamless 0-100% adjustments that sync with sensors or schedules, all flicker-free courtesy of the constant current driver maintaining a power factor >0.9. The integrated motion and standby sensor functions further enhance smarts: in standby mode, it idles at 10-20% output for ambient safety, surging to full brightness on detecting movement within 7-10 meters (adjustable sensitivity), ideal for high-ceiling transitional zones where energy conservation meets uninterrupted usability. Complementing these is the emergency capability, providing up to three hours of battery-backed light (500-800LM at reduced power) during failures, auto-activating to illuminate critical paths and comply with rigorous egress standards like NFPA 101, without relying on cumbersome external modules. Electrically resilient, the ILED-OL-B24W series thrives on 220-240VAC or 110-277VAC at 50/60Hz, with Class I classification ensuring grounded safety against shocks in populated areas. The IP42 rating fortifies it against dust and light splashes, suiting moderately exposed indoor environments like retail floors or school auditoriums, while the solid-state architecture eschews mercury, UV, IR emissions, and RF disruptions for healthier, interference-free operation. Outlasting traditional bulbs by over 50,000 hours, the LumiLEDs source—certified LM80 for lumen maintenance—pairs with the iron frame’s superior heat sinking to prevent degradation, and the PMMA lens’s anti-yellowing formula preserves diffusion clarity across years of service. Certified to CE, RoHS, SAA, and TUV benchmarks under ISO9000 production rigor, it embodies global compliance, recyclable design, and e-waste reduction, aligning with sustainability mandates like BREEAM or WELL. Practicality shines in every detail: surface mounting via pre-attached brackets and quick-wired leads allows installation in under 30 minutes, even on textured ceilings, bypassing the need for recessed tins or plenum access— a game-changer for retrofits in aged buildings. The 3-5 year warranty safeguards against defects and performance dips, with the scalable wattages (from 12W compact starters to 60W giants) enabling tailored deployments: the 500mm suits medium conference rooms with 2880LM balanced neutrality, while the 1000mm floods gymnasiums with 4800LM invigorating daylight. Energy savings are profound—at 100LM/W, it rivals 300W incandescents at a tenth the draw, potentially recouping costs in weeks for 24/7 venues, amplified by sensor-driven automation that curtails idle consumption by 60%. In real-world synergy, this oyster light orchestrates immersive experiences. Picture a bustling hotel atrium where DALI dims the 800mm units to golden 3000K hues for evening events, or a warehouse where motion triggers the 1000mm’s cool beams for safe forklift navigation, emergency failover ensuring continuity amid storms. Architects laud its proportional depth (120-250mm) that avoids visual bulk, and operators cherish the low-maintenance ethos—no ballasts to fail, just quarterly wipes. The CCT flexibility fosters circadian support, with warm tones easing shifts in healthcare wings or cool invigorating retail floors, all emission-free to nurture well-being. This ceiling light transcends replacement; it’s a canvas for innovation. In an era of vast, versatile structures, the ILED-OL-B24W(500/800/1000) commands presence with poise—dimmable, detectable, dependable—illuminating not just spaces but strategies for efficiency and elegance. From echoing halls to humming hubs, it proves oversized doesn’t mean overkill; it’s optimized mastery, lighting legacies one expansive glow at a time.
