What QTL does

QTL, doing business as Q-Tran Inc. and founded in 1993, designs and manufactures specification-grade architectural LED lighting products and controls from its headquarters and manufacturing facility at 155 Hill Street, Milford, Connecticut. Its product ecosystem covers linear LED strips (static white, warm dim, dynamic white, high efficacy, tunable white, extreme temperature, RGB/RGBW), rigid and flexible LED fixtures, an extensive catalog of aluminum extrusions and profiles, point-source lighting (LUCY monopoint), Q-SHEETS backlighting panels, 120V line voltage fixtures, and a full line of LED power supplies (DC, AC, drivers, direct burial, toroids) with broad dimming-protocol support (0-10V, DALI, DMX, Lutron, phase). Differentiated technology includes proprietary WhiteOptics optical technology (yielding 2-52% increased light output depending on extrusion), diode-free UV-stable lens options, one-step/one-bin LED binning for color consistency, and the patent-pending LUCY puck-and-lens system with Venturi-effect passive cooling.

The company sells made-to-order, factory-assembled custom solutions to architects, lighting designers, lighting contractors, and landscape/exterior professionals, with growing emphasis on hospitality and retail specification projects. Go-to-market is sales-led through a nationwide network of manufacturer representatives, complemented by direct engagement and a content-rich website that hosts spec sheets, IES photometric files, Revit/CAD files, and sustainability documentation (Declare labels, EPD, Red List Free). Certified domestic manufacturing, Buy American Act compliance, Build America Buy America Act compliance, UL/ETL/CSA listings, and IK10 impact ratings on select lines position QTL for federal, green-building, and high- specification commercial projects.

The operating model is hardware sales: products are quote-based and built to specification rather than sold off-the-shelf through retail channels. A May 2026 expansion grew the Milford facility to 105,000 sq ft, consolidated former West Coast production onto the East Coast site, and added a new warehouse in Shelton, CT, aligning manufacturing with engineering to support an aggressive product roadmap and entry into exterior/landscape categories. Management is founder-led, with John Tremaine as Founder & Chairman and Gean Tremaine as CEO, supported by a CIO (Jamie Devenger) and CFO (Patricia Donnelly).
