What Justin does

Justin Inc. is a privately-held US manufacturer of low voltage transformer assemblies and Class 2 LED drivers/power supplies, founded in 1956 by Frank R. Justin, Jr. and operating from South El Monte, California. The company's product portfolio is organized into two core categories: Class 2 LED Drivers (including DC Solid State SSD drivers, DC Magnetic DCR power supplies, and AC transformers ranging 36-360 Watts) and Landscape Lighting Controls (Garden Light GL residential series, Multitap MTP professional series, and In-Ground IG direct burial transformers, 100-1200 Watts). All products carry UL listings (UL8750, UL1310, UL1012, UL1838), CSA approval for Canada, and RoHS compliance, with ISO 9001 certification currently in process.

The business operates a direct B2B sales model through its company website using an RFQ (Request for Quote) system, targeting landscape lighting installers, electrical contractors, and LED sign/decorative lighting industry buyers. Revenue is generated through one-time hardware sales of transformer and power supply units plus accessories (photocells, timers, dimmers, surge protectors), with no recurring or subscription revenue model. In-house capabilities span semi-automatic coil winding, CNC fabrication, electromechanical assembly, and electronic design, supporting both standard product lines and custom configurations for professional installer customers in the US market.
