Keystone Sign Hero Direct Wire LED Sign Lamps

Upgrade new or existing illuminated sign cabinets with Keystone Sign Hero Direct Wire LED Sign Lamps, featuring Power Select wattage technology and Keystone Color Select Technology with selectable 4000K, 5000K, and 6500K color temperatures.

Designed specifically for internally illuminated commercial signage, Sign Hero Direct Wire lamps provide 360° LED light distribution for even illumination across double-sided sign faces. The direct-wire design operates on 120–277V input power and eliminates the need for a traditional fluorescent ballast.

This field-selectable design gives installers more flexibility without requiring separate lamps for each color temperature.
