The Juno RED Series™ 4" IC-rated new construction downlight housing is a high-performance solution designed for modern ceiling applications, especially where shallow plenums are present. Ideal for new construction in multi-family residential and commercial environments, this IC-rated housing supports both 120V and MVOLT (120-277V) dimmable drivers, allowing flexible compatibility with a variety of control systems including 0-10V, forward phase, reverse phase, and Triac dimming. The housing meets ENERGY STAR® certification standards and complies with California Title 24 JA8 requirements for high-efficacy LED light sources. When installed according to the International Building Code, Section 714, it helps maintain a maximum two-hour fire-rated ceiling assembly, ensuring both performance and safety.
Constructed with a painted steel housing just 3-1/2 inches deep, the 4-inch square fixture is fully assembled to the plaster frame for easy installation in ceilings ranging from 5/8” to 1-1/4” thick. The pre-wired junction box is ETL listed for through-branch wiring and comes with multiple knockouts for ½” and ¾” conduit as well as NM cable. Removable access plates, pryout slots, and quick-connect electrical connectors simplify the wiring process and enhance installation speed. The 22-gauge die-formed galvanized steel mounting frame includes a pre-installed Air-Loc® gasket that minimizes air leakage, supporting energy code compliance.
The fixture integrates Juno’s Real Nail 3® bar hanger system, allowing secure and flexible installation within joists spaced up to 24 inches on center or in suspended ceilings. The telescoping bars are scored for quick adjustment or clean breaking in tight spaces, and each bar includes captive bugle-headed ring-shank nails for one-step installation and easy repositioning. The integral T-bar notch and locking set screw provide stable, precise placement of the junction box housing, ensuring long-term reliability.
The LED trim module, available in baffle or smooth cone styles, is constructed of durable cast aluminum with an integral flange and a diffusing lens that conceals the LED source while providing uniform aperture luminance. The all-in-one design allows the LED light engine to mount directly to the trim, streamlining installation and ensuring consistent performance. The LED array is binned within a three-step MacAdam ellipse for superior color consistency, available in 2700K, 3000K, 3500K, and 4000K color temperatures with a minimum 90 CRI for excellent color rendering. Superior thermal management is achieved through the die-cast construction, promoting long LED life rated at 50,000 hours at 70% lumen maintenance.
The LED driver options include a dedicated 120V driver and a universal 120-277V driver with a power factor greater than 0.9. The 120V model is compatible with most incandescent, magnetic low-voltage, and electronic low-voltage dimmers, while the universal voltage driver supports 0-10V dimming control, providing designers and installers flexibility in integrating with existing lighting control systems.
Each unit is backed by a five-year limited warranty on LED components and is certified to meet high-efficacy and safety standards. The assembly is ETL listed to UL1598 for U.S. and Canadian markets, suitable for damp locations and indoor covered ceilings rated for wet use. The housing also complies with UL514A standards and maintains an Air-Loc® seal to prevent air leakage into unconditioned spaces.
All performance specifications are based on standardized laboratory testing at 25°C, with real-world performance varying depending on installation and environment. The Juno RED Series™ 4" IC-rated downlight housing delivers a robust, efficient, and code-compliant solution for modern recessed lighting needs—balancing visual comfort, color quality, and ease of installation for residential, commercial, and multi-family construction projects.
