This series includes three recessed retractable adjustable downlight spotlights ET4004(10W), ET4005(20W), ET4007(30W), requiring a unified Φ130mm ceiling cutout for base embedding without large-scale ceiling demolition. Equipped with premium LED chips from Bridgelux, Cree or OSRAM, it delivers high luminous efficacy of 110~120lm/w and works with standard AC220-240V mains. The power range covers small accent lighting up to large-area focal illumination, widely used in show flats, exhibition artwork lighting, hotel guest rooms, corridors and boutique retail. The pre-embedded installation achieves an invisible neat ceiling look, and the lamp head can be replaced separately for after-sales maintenance.
Two CCT options 3000K warm tone / 4000K neutral white can be switched without driver rewiring to shift between ambient warm glow and general functional lighting. CRI≥90 reproduces the original hue and light gradation of paintings, fabrics and exhibits with high fidelity. Higher-power variants adopt reinforced heat sinks to suppress lumen depreciation during nonstop operation, ideal for long-hour all-day service in commercial venues.
Three professional beam angles 15°/24°/38° are optional: ultra-narrow 15° for long-distance sculptural wall grazing on artworks; 24° for sharp focus on window displays and ornaments; 38° for standard ambient flood lighting. The lamp head supports front-back retraction, horizontal rotation and vertical tilt for omni-directional aiming. No modification to the embedded base is needed after rearranging decor or exhibits; users can simply adjust the fixture to reposition the beam.
Honeycomb side vents plus internal multi-channel convection heat sink dissipate chip heat efficiently across the full 10~30W power spectrum, preventing LED burnout and lumen aging caused by trapped heat inside ceiling cavities. The clip-on embedded base enables plug-and-play lamp head replacement to speed up bulk construction. The shallow recessed design barely protrudes from ceilings, and the minimalist industrial look fits modern, minimalist and light luxury interior decoration styles.
It natively supports full extended intelligent protocols including DALI bus dimming, Bluetooth group linkage, D2W dual CCT switching, scene preset and Tunable White stepless color tuning. Compatible with building central control and smart home systems, it realizes zoned grouped dimming, timer switching and one-touch multi-fixture scene activation. Certified with CE in compliance with international residential & commercial lighting standards, it is widely adopted in standardized bulk bidding projects such as real estate mass fit-outs, hotel chains, cultural exhibition halls and commercial complexes.
