This series consists of two deep anti-glare large-caliber recessed downlights: ED4003 (6 inch) with 10W/12W/15W power and Φ150mm cutout, ED4004 (8 inch) with 25W/30W/35W power and Φ200mm cutout, both compatible with AC220-240V mains supply. Adopting deep-cup anti-glare design and large luminous surface, they are specially applied to large-area main lighting for living rooms, dining areas, hotel lobbies and retail shop windows. Multiple power and cutout options fit new ceiling construction and old lamp renovation, offering wide compatibility for project selection.
Three CCT options (2700K warm tone / 3000K warm white / 4000K neutral natural light) support wiring-free on-site switching without circuit modification to meet lighting demands for cozy residential ambiance, merchandise color rendering and public office illumination. Luminous efficacy reaches 120lm/W with excellent photoelectric conversion efficiency and optimized power consumption, slow lumen depreciation during long-term operation for energy saving and durability. CRI≥90 accurately restores the original color of soft furnishings, displayed goods and wall finishes for delicate visual performance.
The fixed ultra-wide 100° flood beam angle delivers broad and even light distribution with soft light transition and no harsh hotspots or obvious edges. Each lamp covers a large illumination area, effectively reducing installation quantity and cutting overall procurement & labor construction cost. The recessed deep anti-glare structure hides the light source inside the reflector cup to eliminate direct glaring light, greatly improving eye comfort during prolonged residential, commercial and office use.
The integrated radial multi-fin aluminum heat sink on the rear features an oversized convection heat dissipation cavity to rapidly dissipate heat during long continuous operation of both low and high power modes, preventing LED aging, flicker and burnout caused by heat buildup inside enclosed ceilings. With IP20 indoor protection grade, screw-free spring clip mounting prevents loosening and falling off. The fixture sits flush with the ceiling for a minimalist elegant look, and housing colors such as black and white can be customized on request.
It natively supports comprehensive intelligent control protocols including DALI bus dimming, Bluetooth group linkage control, D2W dimming, scene preset and Tunable White stepless color adjustment. It can be connected to building central control and whole-house smart home systems to realize zoned dimming, timed switch and one-click multi-fixture scene linkage. With CE certification complying with global indoor lighting electrical standards, it is widely used in bulk lighting projects such as whole-house no-main-light illumination for luxury residences, chain retail stores, star hotel public areas, catering spaces and office building corridors.
