Keystone Sign Hero lamps are the perfect solution for retrofits and new sign installations. They're also great for single and double sided signs as well. Keystone's LED sign tube provides the same light output as traditional fluorescents, while having a longer useful life, reducing maintenance and replacement costs.
Sign Hero lamps use Keystone's DirectDrive technology, eliminating the need for an external driver or ballast while allowing you to use the existing sign sockets. They ballast bypass design saves installers and technicians time in the field.
Keystone Sign Hero 360 and 180 degree tubes have optical lenses to cover each individual LED chip, which helps eliminate hotspots and ensures consistent light distribution across both faces of the sign. View the full selection of Keystone Sign Hero Tubes here.
