Unpacked: SDL Ultrathins

Discover how NSL’s SDL Ultrathin downlight multipacks deliver convenience, quality, and value—part of our renewed commitment to reclaim leadership in the market we helped create.

SDL Ultrathins deliver seamless, unobtrusive lighting that brightens the space while complementing accent and statement fixtures. The perfect blend of performance and design, they let the room—not the light—take center stage.

For more than 38 years, NSL has been part of the story of lighting in North America—designing products that bring spaces to life while building lasting relationships along the way. Our journey has always been guided by one thing: listening to the people who use our products. This magazine, and our newest innovations, are both part of that ongoing conversation.

That’s why we created the SDL Ultrathin Series—a product designed to compete on price without compromising on quality. From its anti-yellowing lens to its galvanized steel backplate, aluminum trim, and larger junction box with extra knockouts, every detail reflects the needs of the people installing and living with these fixtures. The SDL meets the latest Energy Star standards, Title 24 compliance, and is ETL listed for wet locations—features often missing from low-cost
alternatives.

Convenience is also key. Our multipack format answers a growing call from contractors for faster installs, reduced waste, and better project value. It’s one more way we’re helping our customers save time and money while maintaining the high standards they expect. And with FT4 fire-rated cable and 5CCT selectable color, the SDL Ultrathin delivers the flexibility and safety today’s market demands.

The slim downlight category—one we helped pioneer—has changed dramatically in recent years. What began as an innovation in sleek, efficient design became a commodity market, where price often trumped performance. We heard from contractors, distributors, and designers that while pricing matters, value matters more. People still want a product they can trust: one that installs easily, looks great, and lasts.

We also know the risks that come with low-quality lighting: callbacks, failures, frustrated clients. That’s why NSL stands firmly behind every product we sell, with industry-leading customer service and a full five-year warranty. As a family run company, we take pride in doing things the right way— even when it’s not the easy way.

The lighting industry will keep changing—but NSL’s commitment to innovation, quality, and integrity won’t. With the SDL Ultrathin, we’re not just back in the game—we’re leading the way forward.
