What Troy - Csl Lighting does

Troy-CSL Lighting, Inc. is a privately held, City of Industry, California-based corporation founded in 1967 that designs and manufactures performance-engineered LED lighting systems for commercial, hospitality, residential, and retail applications. Its primary operating brand, CSL Lighting, sells a portfolio of recessed downlights, cylinder fixtures, multiples, and RLM luminaires built around three patented or proprietary technology platforms: Silent Vu™ low-glare optics, GyroShift™ tool-less bezel-and-ball adjustment, and CSL Point Source LED technology. The portfolio spans sub-brands including Whisper, Acrobat, ECO, GyroShift, CSL Forme, Entity, CSL Luxe, and standard Cylinders, with products certified to UL, IC, wet/damp location, CCEA, ENERGY STAR, California Title 24 JA8, ADA, and airtight standards.

The company generates revenue through hardware sales of LED fixtures, sold exclusively through a regional network of authorized sales agents in North America rather than direct e-commerce, with a QuickShip program supporting faster project delivery for time-sensitive specifications. Target buyers are architects, lighting designers, and contractors specifying fixtures for new construction and remodel projects, with named reference installations in hospitality (Uchi West Hollywood) and commercial interiors. Pricing is not publicly disclosed; customers are routed to sales agents. In February 2026, the parent entity expanded beyond lighting fixtures by acquiring the Schoolhouse home goods brand from Food52's bankruptcy estate for $2.2 million, and earlier co-developed the CSL Luxe decorative line with Hudson Valley Lighting, signaling a broader brand-portfolio and segment-expansion strategy.
