The Juno R612L TEK LED track spotlight brings together refined simplicity, strong performance, and versatile application flexibility. With its clean geometric form and modern cylindrical housing, the fixture blends seamlessly into a wide range of environments—from retail and hospitality settings to galleries and commercial interiors. Delivering up to 3339 lumens while consuming only 38 watts, the R612L achieves efficacies of up to 90 lumens per watt and maintains consistent color quality throughout its long 50,000-hour rated life. Four available color temperatures—2700K, 3000K, 3500K, and 4000K—allow lighting designers to tailor ambiance and visual warmth, while standard 80 CRI or optional 90 CRI versions provide flexibility in meeting varying color rendering requirements.
Constructed from precision die-cast aluminum, the housing ensures excellent thermal management and long-term performance, maintaining at least 70 percent of initial lumen output after 50,000 hours of operation. The sleek and timeless cylindrical form complements any architectural setting, available in white, black, or silver finishes to suit diverse aesthetic needs. The fixture’s unique nested yoke arm design allows for straightforward, straight-down aiming when desired, and delivers full adjustability with 360° horizontal rotation and 95° vertical tilt, ensuring precise light placement across varied display or task applications.
The R612L utilizes a high-performance LED array that ensures color consistency within a 2-step MacAdam Ellipse, minimizing perceptible color variation between luminaires. Standard models deliver a minimum 80 CRI, while high-CRI options offer 90 CRI for applications demanding exceptional color accuracy. The integrated solid-state driver is positioned within the housing behind the LED light engine, reducing the overall footprint and optimizing thermal operation through an insulating air gap and thermal potting compound. The driver is Class 2 compliant and includes built-in overcurrent and short-circuit protection. It also ensures quiet performance with or without dimming, and all 120V versions are dimmable using factory-approved reverse-phase electronic low-voltage (ELV) dimmers. The fixture meets FCC Part 15 Class B EMI standards, ensuring reliable and compliant operation in commercial and residential environments.
Optically, the R612L employs precision-engineered reflectors that deliver uniform spot, narrow flood, flood, or wide flood distributions. The faceted or dimpled reflector design ensures even color mixing and smooth beam transitions. Accessory reflectors are available for field conversion between beam distributions, while an optional accessory holder—replacing the front bezel without tools—can be factory-installed or added later, accommodating one accessory such as a lens, louver, or filter as desired.
The fixture’s universal compatibility further enhances its utility. With the TEK track adapter, the R612L integrates seamlessly into Juno Trac-Lites and Trac-Master track systems, as well as many competitive 120V systems. The universal adapter is UL recognized for use with ConTech LT Series track and features copper alloy contacts for consistent electrical connection without arcing, a spring-loaded positive latch, an integral on/off switch, and embossed polarity arrows for easy orientation. Alternative adapter options—including TEK, HTEK, GTYPE, HTYPE, and LTYPE—allow the R612L to be factory-assembled for a range of system-specific track installations. Each adapter maintains secure, polarized insertion and optional circuit selection capability, enabling easy switching between circuits and individual fixture servicing.
The R612L is UL and cUL listed for dry locations, with 80 CRI versions qualified under the DesignLights Consortium® and 90 CRI versions certified as Title 24 compliant for California energy regulations. The fixture is union made and assembled in the United States, qualifying under multiple domestic manufacturing acts including the Buy American Act (BAA), Build America Buy America (BABA), and DOT Buy America regulations.
Combining timeless form, solid-state reliability, and adaptable optical control, the Juno R612L TEK LED track spotlight stands out as an efficient and versatile lighting solution. Its blend of precise engineering, color consistency, and compatibility with multiple mounting systems makes it ideal for professional lighting environments requiring both performance and simplicity.
