History

SloanLED: A Legacy of Innovation and Global Reach.

Founded in 1957 by Charles Sloan, SloanLED quickly emerged as a pioneer in high-reliability lighting products. Guided by two core principles—employing the latest technologies to develop quality lighting solutions and providing outstanding customer care—SloanLED laid the groundwork for decades of innovation in LED lighting. The company became one of the earliest adopters and developers of LED technology, earning a reputation for excellence in signage, architectural, petroleum, retail, and hospitality lighting applications.

With over 150 dedicated employees across the globe and operations spanning North America, Europe, and Asia, SloanLED offers one of the most extensive global support networks in the industry. Headquartered in San Angelo – Texas, with additional offices in the Netherlands and Asia, the company delivers localized service with a global reach—from Alaska to Australia.

SloanLED’s solutions are known for their energy efficiency, long-lasting performance, and ease of installation. Designed to reduce energy and maintenance costs while offering consistent brightness and superior uniformity, SloanLED’s products help clients achieve a faster return on investment and lower total cost of ownership.

In October 2022, SloanLED became part of Principal Industries, a leading provider of electrical components and services to the commercial sign industry. The acquisition expanded Principal’s product portfolio and market presence, combining SloanLED’s strength in engineering and global reach with Principal’s strategic capabilities.

Principal Sloan, the brand created through the union of SloanLED and Principal LED, represents the best of both companies. Offering an expanded range of innovative LED lighting solutions—from channel letters and cabinet signs to architectural and specialty applications—Principal Sloan continues to simplify lighting for its customers. With a shared commitment to quality, innovation, and customer service, Principal Sloan sets a new standard in the industry.

SloanLED’s enduring legacy is not just about lighting—it’s about brightening brands, reducing costs, and building lasting relationships. More than 150 employees strong and backed by the combined power of Principal Industries, SloanLED continues to illuminate the world with unmatched expertise and reliability.
