The product range includes Sign Hero® LED sign tubes, Sign Base Station LED cabinet systems, HID LED replacement lamps, Pocket Drivers, electronic sign ballasts, floodlights, wall packs, canopy fixtures, and outdoor linear fixtures for sign cabinets, channel letters, monument signs, exterior signage, and lighting retrofit work. Keystone identifies its broader product lane as LED lamps, modules and light engines, fixtures, power supplies, and controls.
Sign Hero® LED sign tubes cover new and retrofit cabinet signs, replacing traditional T12HO and T8HO fluorescent sign lamps with direct-wire LED tubes that use integrated drivers instead of external LED drivers. Sign Base Station covers large, deep, double-sided sign cabinets using LED HID replacement lamps. Pocket Drivers provide compact constant-voltage power for signage layouts. Electronic sign ballasts serve fluorescent sign systems and ballast replacement work. Floodlights, wall packs, canopy fixtures, and outdoor linear fixtures cover non-internally illuminated building signs, exterior lighting, parking areas, wall lighting, and covered outdoor applications.
Keystone lighting products separate by lamp type, voltage, driver configuration, ballast requirement, cabinet depth, sign size, beam spread, color temperature, lumen output, mounting method, and retrofit format. LED sign tubes handle internal cabinet illumination and fluorescent lamp replacement. Power supplies and drivers regulate electrical output for LED systems. Ballasts remain part of fluorescent sign service and replacement work. Exterior fixtures define lighting by mounting location, light distribution, weather exposure, and the area being illuminated.
