Pre-wired, install-ready, and purpose-built for interior, exterior, and high-density applications — QTL enclosures are designed to perform.
Modern lighting projects face new challenges, many of them driven by how power is deployed. Scattered individual power supplies, ill-fitting enclosures, and limited access points can make coordination difficult and inefficient. Add more sophisticated controls and integrated fixture power, and it becomes harder to maximize performance while keeping labor and installation timelines in check.
QTL LED power supply enclosures are designed to calm chaos. During construction, enclosures can be pre-shipped from the factory with multiple power supplies already integrated, reducing on-site labor and simplifying installation. They’re then ready for placement within standard wall studs, above drop ceilings, or between ceiling joists wherever the project demands.
Once installed, enclosures centralize zones and dimming protocols, making today’s advanced control systems easier to manage. And with accessible, organized power supplies, ongoing maintenance, upgrades, and repairs become faster, cleaner, and more sustainable.
QTL LED power supplies are proven performers designed to support not just the fixture, but the full lighting system. With advanced capabilities that deliver consistent output, precise control, and long-term reliability, they give every project a stable, scalable foundation that reduces failures and ensures dependable LED performance over time.
QTL enclosures take that same proven performance and build on it. Engineered to house multiple power supplies in a single, organized unit, they deliver greater power density, cleaner installations, and better protection for the components inside. Pre-wired and install-ready, they arrive ready to drop into place, cutting on-site labor and simplifying coordination without sacrificing the quality and reliability QTL is known for.
Higher-density power enclosures not only increase capacity, they improve how projects are designed and executed. By supporting more drivers and wattage within a single enclosure, they reduce the number of cabinets required, freeing up valuable space and simplifying layouts.
Fewer enclosures also mean less wiring, fewer connections, and reduced coordination between trades, helping projects move faster from rough-in to final install. And with additional capacity built in, systems are better prepared for expanded zones, evolving controls, and future upgrades without requiring redesign.
The result is greater design freedom, improved efficiency, and a power infrastructure that scales with the project, not against it.
Every QTL power supply enclosure is designed to deliver what matters most on the job:
Durability — QTL enclosures are rigorously tested and engineered to perform in real-world conditions, not just controlled environments. Built to withstand the demands of commercial and residential installations alike, they protect the power supplies inside and help extend the reliable performance of the entire lighting and power system over time.
QTL offers enclosure solutions for every application. Whether the project calls for a standard interior installation, an exterior environment, or a high-density configuration, there is a QTL enclosure designed for it.
When projects scale up, the QT-CAB scales with the highest density options. IC-rated for indoor safety, this high-density enclosure fits up to 10 DC drivers with up to 1,000 watts max total output in a surface or recessed mount, consolidating more power into a single, efficient footprint. Rigorously tested and UL-listed, it’s built for the most demanding specifications.
QTL’s interior-rated, compact LED power supply center fits up to 5 drivers with up to 500 watts max total output. Available in surface-mount or recessed configurations with AC or DC power and 0–10V dimming, the QTM delivers flexible, centralized power for a wide range of interior applications. QTM is also IC-rated for direct contact with insulation.
Purpose-built for exterior environments, the QOM surface-mounted enclosure supports up to 4 drivers with up to 400 watts max total output. Enhanced 0–10V dimming, along with isolated and regulated output, ensures safe, reliable performance in exposed and demanding conditions.
When the project moves outside and into the ground, QTL has an enclosure solution for that too. Q-SCAPE is QTL’s award-winning direct burial power system, purpose-built for landscape, pool, spa, and low-voltage lighting applications. Designed to be embedded in lawns, gardens, hardscapes, and concrete, it delivers the same reliability you expect from every QTL product.
