Lightruss

Lightruss is a unified, organized way to systematically hang an indirect lighting system. It reduces glare while softly and evenly illuminating surrounding areas.

Tried and tested, this flagship family has more than 1,000 installations throughout North America. Partner with our experienced applications team to tailor your Lightruss solution.


Why Indirect Lighting?

In spaces where reducing glare, enhancing comfort, or improving light uniformity are top priorities, indirect lighting is an ideal choice. Recent advancements in optical efficiency and LED performance have facilitated the development of smaller, more powerful, indirect lighting fixtures that control light better than ever before. This is enabling a new generation of buildings to enjoy the benefits of indirect lighting while meeting energy code requirements.




What is Lightruss?

SPI Lighting revolutionized how to indirectly light spaces when it introduced Lightruss three decades ago. Today, it remains one of the best ways to illuminate open spaces. Lightruss combines a suspended modular truss support system and performance lighting modules to deliver illumination for a wide variety of applications. Integrated state-of-the-art LED technology has modernized product offerings to include luminaires that generate efficacy of up to 100 lumens per watt, up to 73,560 lumens per fixture, and more than 100 footcandles.

What are the benefits?

The system’s streamlined design fully encapsulates wireways and eliminates vertical stems, presenting the clean visual package sought after by today’s architects. It can be designed to blend with ceiling construction or to add a visual accent.

Lightruss saves building owners 25 to 30 percent on installation costs by reducing the number of power drops and conduit requirements. Beyond that, the truss framework enables the ideal positioning of luminaires regardless of ceiling impediments such as supports, HVAC, and other systems, making it popular choice with engineers.

It is a favorite for lighting natatoriums. Because Lightruss minimizes glare on waters’ surface, it improves the visibility of lifeguards and enjoyment of spectators. Designed to light from the perimeter, it eliminates fixtures over pools. Lighting modules are easily maintained without disassembling the entire system. It’s damp-rated, durably constructed, and proven to last in harsh environments.




Is it hard to specify?

Not at all! To ensure each system is tailored to your job requirements, our experienced applications team provides complimentary engineering support on all Lightruss products – from initial inquiry to final installation. Here’s how it works:

Start Design Installation
An experienced Lightruss application engineer will interface with you and your design team to obtain the illumination and space parameters needed to begin the system design. We will provide application photographs, budget parameters, and references from similar projects, if applicable. A complete set of documentation will be provided for inclusion in your bid. Overall layouts, circuiting diagrams, and construction details are supplied. Our local representatives, in partnership with our Lightruss team, provide final project pricing and can walk contractors through the installation process to ensure they are comfortable with how the system is supplied and installed. Lightruss is pre-wired, each light module is aimed, and every section is pre-assembled at the factory. Each section is also individually packaged for shipment and ease of handling. Each package and component is keyed to the installation drawings so all components are easily identified at the job site.
