The Keystone KT-LED31T8-72P2S-8(XX)-D /G2 72" (6 Foot) LED Sign Tube consumes just 31 watts of 120-277 volt energy to produce 3840-4000 lumens of your choice of either 4000K Cool White or 6500K Daylight illumination. Keystone's DirectDrive technology eliminates the need for an external driver or ballast, while still using the existing sockets. The Keystone LED Sign Tubes feature a rotatable R17d base for correct lamp orientation in vertical or horizontal installations, regardless of how the socket was originally installed. These LED retrofit tubes DO NOT require an external LED driver. The existing ballast must be bypassed. This product has a CRI of 80 and an operating temperature of -22°F to 131°F. This LED tube measures 69.91" long by 1.1" in diameter, to fit your sign applications, and is evaluated to UL 48 / UL 879A Standards and listed in the UL SAM Manual.
