The T387L LED track head with TEK adapter combines timeless aesthetics with cutting-edge performance, presenting a refined evolution of traditional track lighting. This 46-watt fixture delivers up to 4,651 lumens of output while consuming up to 80 percent less energy than comparable halogen sources. With a rated life of 50,000 hours, it provides exceptional longevity and reliability for retail, gallery, or commercial applications. The T387L is available in 2700K, 3000K, 3500K, and 4000K color temperatures with 80 or 90 CRI options, offering excellent color consistency within a 3-step MacAdam Ellipse. For spaces requiring enhanced color fidelity, optional SpectralWhite versions deliver 90+ CRI and superior color rendering that enriches hues and brings out naturally brilliant whites.
Built with a durable all-metal housing and a custom heat sink, the T387L achieves outstanding thermal management and maintains a minimum of 70 percent of its initial lumen output at 50,000 hours of operation. Its passively cooled design operates silently and includes no moving parts, ensuring long-term dependability. The driver, assembled in a vertically mounted side housing, minimizes the fixture’s overall footprint while maintaining an insulating air gap between the driver and LED light engine to optimize thermal performance. Quiet operation is ensured with or without dimming, and the 120V models are compatible with high-quality reverse phase electronic low-voltage (ELV) dimmers approved by Juno. The solid-state driver is Class 2 compliant, includes integral overcurrent and short-circuit protection, and meets Class B FCC Part 15 requirements for electromagnetic performance.
At the optical core, the T387L uses interchangeable, computer-designed total internal reflection (TIR) optics to deliver precise and uniform distributions in spot, narrow flood, flood, or wide flood configurations. A single optic is supplied based on the catalog specification, while additional optical assemblies can be used to alter the beam pattern in the field. The integral, bayonet-mounted accessory holder accommodates up to two accessories such as filters, lenses, snoots, or louvers, enabling additional light control customization as needed. The fixture provides full 360-degree horizontal rotation and more than 90 degrees of vertical aiming flexibility, allowing precise directional adjustment in any installation.
The T387L maintains a clean architectural profile with concealed wiring and a vertically oriented aluminum driver housing that complements its slender cylindrical shape. Available in white, black, or silver finishes, it integrates seamlessly into both modern and traditional interiors. The combination of form and function produces a refined, understated presence ideal for retail displays, galleries, museums, or hospitality environments requiring both performance and style.
The fixture mounts easily using the TEK adapter, which is compatible with Juno TEK track systems. For broader compatibility, alternate adapters are available for HTEK, HTYPE, LTYPE, and GTYPE tracks, ensuring versatility across multiple track infrastructures. The TEK adapter includes polarized construction to prevent reverse installation, a rotary circuit selector for simple circuit switching, and an integral on/off switch for individual fixture control during servicing. Copper alloy contacts maintain precise spring action with no arcing or deformation over time, while a spring-loaded positive latch ensures secure mounting to the track.
As part of Juno’s universal track system design, the T387L can also be used with 1-circuit or 2-circuit Trac-Master and Trac-Lites tracks, as well as monopoints and specialized mounting options. Its high-quality electrical grounding and UL recognition for use on ConTech LT Series track systems provide broad adaptability across professional lighting environments.
Every component of the T387L reflects durability, quality, and efficiency. It carries UL and C-UL listings, ENERGY STAR® certification, and DesignLights Consortium® qualification on 90 CRI versions, excluding the HTEK adapter option. Both 90 CRI and SpectralWhite configurations comply with California Title 24, Part 6 requirements for high-efficacy LED light sources. The fixture is union-made and assembled in the United States. It also meets government procurement standards, qualifying under the Buy America(n) Act (BAA) and the Build America, Buy America (BABA) regulations, certifying it as a domestically manufactured product for federal and infrastructure projects.
With lumen packages up to 4,600 lumens, superior color rendering, multiple beam configurations, and flexible mounting compatibility, the T387L LED track head exemplifies the balance between timeless design and modern performance. Its precision optics, efficient thermal design, and adaptable control options make it a dependable, visually refined solution for architectural environments requiring consistent quality and long-term efficiency.
