The 4.5-inch adjustable LED downlight from ID+ is a high-performance, versatile luminaire designed to meet the demanding needs of commercial, hospitality, retail, museum, gallery, and residential applications. Engineered as part of a cohesive family, the luminaire ensures consistent aesthetics and uniform light quality across all installations. With high lumen outputs, multiple beam spreads, and precise color control, it delivers both functional and accent lighting solutions while offering a broad range of options for standard white light at CRI 80, 90, or 97*, as well as two warm dim spectra at CRI 90. These warm dim ranges emulate the natural black body curves of halogen and incandescent sources, offering lighting that enhances ambiance and occupant comfort.
The luminaire is designed for effortless installation and field adjustability. Its low-profile 4- to 5-inch housing accommodates shallow or restricted plenum spaces, while tool-less adjustment allows 0°-40° vertical tilt and 364° rotation for precise aiming, even on sloped ceilings. Field-changeable optics and a slide-on mechanism enable easy switching between downlight and wall wash configurations post-installation. Available housing types include IC, non-IC, and wood ceiling-compatible versions, while a wood ceiling installation kit further supports architectural flexibility. Butterfly brackets, bar hanger options, and integral junction boxes with multiple pry outs ensure compatibility with a wide variety of ceiling constructions.
The optical system incorporates a parabolic reflector cone crafted from die-cast aluminum to provide glare-free illumination. Trim features torsion springs that secure the luminaire to the ceiling with no visible fasteners, while self-flanged designs ensure a clean, seamless appearance. Solite lens options, including spot and linear spread distributions, allow precise beam shaping, with spot optics achieving candle power up to 28,962 candelas for highly concentrated accent lighting. Beam spreads range from 12° for focused object illumination to 90° for wide-area ambient coverage, with additional narrow and wide flood options. Trim finishes include clear diffuse, warm diffuse, black, and white, with optional painted flanges and a suite of nature-inspired finishes from The Naturals collection.
The proprietary LED module features a single light-emitting source available in 2700K, 3000K, 3500K, or 4000K with CRI options of 80+, 90+, and 97+, achieving exceptional color accuracy within 2 SDCM and 3-5 SDCM for warm dim operation. Thermal management is optimized through an aluminum heat sink integrated into the extruded or die-formed housing. Dimming and control options are extensive, including 0-10V dimming to 0% or 1%, forward phase, Lutron Hi-Lume EcoSystem, DALI 0% or 1% dimming, and low-voltage PoE compatibility. Emergency functionality is supported with a 7W battery providing 90 minutes of output, suitable for installations up to 19 feet, with above-ceiling access required for service.
Durability and long-term performance are emphasized throughout the design. The luminaire is UL and cUL listed, suitable for dry, damp, or wet indoor locations, with outdoor-rated versions available for recessed covered ceilings. Lumens range from 1000 to 4000, depending on configuration, with warm dim options available for 1000, 1500, and 2500 lumens. Color temperatures include static white from 2700K to 4000K, with warm dim ranges of 2700K–1800K and 3000K–1800K. Lumen maintenance is exceptional, with reported L70 at over 55,000 hours and calculated L70 at 204,000 hours. The luminaire’s lightweight design, under 15 pounds, facilitates installation while maintaining robust construction.
Trim and accessory options provide further flexibility. Aperture options include 4.5-inch round, with trim types such as round die-cast overlap and trimless for seamless integration. Spot distributions with no lens are available for tilts from 0°-40°, with shrouds to conceal internal components for a premium appearance. Distribution kits allow field changes of beam spread, and trimless wood kits are available for wood ceiling applications. Overall, the 4.5-inch adjustable LED downlight offers a comprehensive solution for ambient, task, and accent lighting, combining architectural elegance, adaptable performance, and long-term reliability in a single premium package.
