Keystone KT-LED13T8-48G-840-X3

KT-LED13T8-48G-840-X3 Product Description

Keystone's X3 series T8 LED single or opposing-end wired ballast bypass OR ballast compatible lamps are an excellent choice to replace your conventional T8/T12 fluorescent tubes with long lasting, energy efficient LED illumination.

For ballast compatible (Type-A) installations, these lamps can be installed without any changes to the fluorescent ballast wiring. Installation is as simple as switching out the fluorescent tubes with T8 LED tubes. Should the instant start ballast fail, simply take it out and connect the T8 LED tube directly to the line voltage. This allows you to keep using the same lamp instead of replacing it.

For ballast bypass (Type-B) installations, just connect the tube directly to the 120-277V line voltage following the wiring diagrams. They’re compatible with most instant start electronic T8 ballasts.
