Day Troffer Lights redefine mainstream LED lighting by merging visual comfort, performance, and installation flexibility with energy efficiency and architectural integration. Engineered to meet increasingly stringent building codes, the Day luminaire supports optional integral controls to further reduce power consumption while delivering high-quality illumination across various environments. With a slim 3 7/8-inch housing depth, it is perfectly suited for installations in shallow plenums, offering versatility without sacrificing performance.
Available in both recessed and surface-mounted configurations, Day LED luminaires offer soft, diffused brightness through a choice of curved or flat lens designs. The clean lens frame houses a contoured optic that hides the LED array while ensuring uniform illumination and excellent color consistency. The luminous quality, combined with low-glare output, enhances comfort for occupants and is ideal for workplaces, classrooms, and other high-use spaces.
Designed with practicality and reliability in mind, Day fixtures provide luminaire efficacy exceeding 90 lumens per watt, with available outputs ranging from 2700 to 4000 lumens. The use of OptimaLED technology and mid-flux LEDs ensures energy-efficient lighting without compromising on softness or visual appeal. The choice of curved or flat center optics and either lens or baffle-style configurations adds visual interest while supporting application-specific needs.
Air return functionality is integrated discreetly into the luminaire’s sides, enabling exhaust airflow into the plenum without the need for visible return grilles. This clean and organized ceiling solution enhances aesthetics and function. For installations in T-bar ceilings, the door frame aligns with ceiling runners and tiles, while drywall ceiling installations benefit from a dedicated mounting kit for easy and secure placement.
Day luminaires support a broad range of advanced lighting control protocols, including Lutron’s Hi-lume 1% EcoSystem with Soft-on, Fade-to-Black, as well as DALI, DMX, and Xitanium SR for sensor-based wireless control. BIOS technology is available with static or dynamic spectrum control, including SkyBlue® and Bio-Dimming™ options. BIOS Tunable White systems provide biologically optimized light transitions from 4000K to 2700K, enabling human-centric environments. Axitune-compatible versions offer additional color tuning flexibility. Power-over-Ethernet (PoE) drivers are also supported, including options from Molex, Igor, and Smartengine.
Built from robust materials such as die-formed cold rolled steel and extruded aluminum, Day luminaires are engineered for durability. Their highly reflective matte white powder coat finish helps diffuse glare and enhances lighting efficiency. Spotless acrylic lenses and precision PMMA blends in the side lenses eliminate pixilation while maximizing light transmission. Optional integral emergency battery packs or emergency circuit configurations are available to support life safety needs.
Day luminaires are offered with input voltage compatibility ranging from 120V to 347V, including universal and DC options. With CRI ratings of 80 or 90 and advanced BIOS versions maintaining R9 values over 75 across all CCTs, these luminaires maintain accurate and pleasing color rendering. Color temperatures range from 2700K to 4000K, maintaining 3-step MacAdam ellipse consistency both within and between fixtures. Designed to perform for a minimum of 50,000 hours at 85% lumen maintenance, Day luminaires comply with IES LM-80 standards and are rated for dry and damp locations in ambient temperatures from 0°C to 40°C (32°F to 104°F).
Altogether, Day Troffer Lights offer a seamless combination of sustainable performance, visual comfort, and architectural refinement—making them a smart and stylish solution for today's energy-conscious environments.
