Keystone Technologies

Keystone Technologies has built commercial and industrial lighting since 1945, when the company got its start in Philadelphia. It now operates manufacturing hubs and distribution centers across the United States and carries one of the broadest LED catalogs in the trade under a single brand: lamps, fixtures, power supplies, controls, and light engines. On a typical job, that range means the troffer in the ceiling, the high bay over the warehouse floor, the corn cob retrofit in the parking lot, and the emergency driver behind the wall can all come from one manufacturer with consistent quality and documentation.

The retrofit and replacement lines tend to get the most attention on a bid. Keystone's HID replacement lamps, including the high-output corn cobs, drop into existing metal halide and high pressure sodium fixtures and cut energy use without a full fixture change-out. Many Keystone products are made in America and are DLC Listed to qualify for utility rebates, which helps when a customer is weighing payback on a project. The fixture catalog runs deep on the indoor side, with back-lit panels and troffers (including integrated emergency versions), low-profile wraps, high bays, strips, and vapor-tight units, and on the outdoor side with wall packs, area lights, floodlights, and canopy fixtures.

Keystone also builds its own controls. The SmartLoop wireless Bluetooth system handles occupancy sensing, daylight harvesting, and scheduling for spaces that need code-driven controls without a complicated commissioning process. TAA-compliant options are available for federal and government work.

RelightDepot stocks the Keystone catalog and supports the people who buy and install it. We turn quotes around quickly, help match a specified fixture to the right Keystone equivalent when a substitution is allowed, and answer the product-level questions (voltage, CCT options, lumen output, mounting) that decide whether a part actually fits the job. On new construction, a retrofit, or a service-call replacement, our team can confirm availability, lead time, and the details that keep an order moving.
