Lighting a Legacy!

Lighting the Way Since the Early 1900s: The Heritage of Bock’s RLM Fixtures

Our RLM fixtures aren’t just lighting—they’re a commitment to quality that’s over a century in the making. Originally produced under our founders, Spero Lighting, these fixtures trace their roots to the early days of industrial lighting. Back then, RLM standards emerged as a national benchmark, ensuring consistency, reliability, and performance in every fixture. Today, Bock Lighting proudly upholds these traditions with our RLM series, designed to meet the needs of both modern and classic spaces.

 What Makes RLM Standards Special?

The RLM standards were established to assure buyers that any lighting fixture bearing the "RLM" label met rigorous quality benchmarks. This label became a mark of trust, symbolizing:

• High Light Output: Providing efficient illumination to cover large spaces effectively.
• Ease of Installation & Low Maintenance: Durable design that resists corrosion, is easy to re-lamp, and requires minimal upkeep.
• Glare Reduction & Visual Comfort: Ensures balanced lighting that reduces eye strain and enhances comfort.
• Reliable Construction & Safety: Protects against electrical hazards, rust, and chipping, making it suitable for tough industrial settings.

Bock Lighting’s Commitment to RLM Heritage

Every RLM fixture we produce today carries the same assurance of quality that Spero Lighting promised nearly a century ago. As one of the early adopters of RLM standards, we’ve stayed true to the commitment that each fixture will deliver balanced, efficient, and comfortable lighting. Our RLM series maintains the same quality assurance, combining iconic vintage designs with modern advancements. With options for LED integration, a variety of colors and finishes, cloth cords, and multiple mounting styles, our fixtures are as adaptable as they are timeless. When you choose Bock Lighting, you’re choosing a piece of lighting heritage built to perform and endure.
