Keystone Sign Hero Contractor Prime LED Sign Tubes
Keystone Sign Hero Contractor Prime is an economical LED sign-tube family for internally illuminated sign cabinets. These ballast-bypass line-voltage tubes combine a built-in Keystone driver, selectable 4000K/5000K/6500K color temperature, frosted construction and rotatable R17d end caps to simplify fluorescent sign-cabinet retrofits while maintaining broad, even illumination.
Key Features & Benefits
- Three selectable color temperatures: 4000K, 5000K and 6500K
- Ballast-bypass design eliminates the fluorescent ballast
- Built-in LED driver; no separate external LED power supply is required
- Rotatable R17d end caps help accommodate existing socket orientation
- Double- and single-ended wiring capability on the verified Contractor Prime family
- Frosted tube construction for broad sign-face illumination
- Sold by the case of 10 in the CrafterNV variants

- New internally illuminated cabinet signs

Selection & Installation Guidance
Select the tube length that matches the cabinet and existing lamp spacing, then choose the desired CCT at installation. These tubes are designed to bypass the fluorescent ballast; they are not ballast-compatible Type A lamps. The existing R17d sockets can be retained when suitable, but wiring must follow Keystone's installation instructions and applicable electrical codes. For socket-free new construction or retrofits with damaged sockets, Keystone's separate Sign Hero Direct Wire system may be a better fit.
