Allen-Bradley 800T-N77R LED Cluster Lamp Bulb

Allen-Bradley 800T-N77R LED cluster lamp bulb is the red LED replacement bulb for 30.5 mm Allen-Bradley 800T cluster pilot lights used in 800T push-button and indicator assemblies. This LED lamp is designed for AC operation and is cataloged as a direct replacement within the 800T LED lamp lineup. The 30.5 mm footprint matches standard 800T cluster housings, and the N77R designation identifies the red LED variant of the cluster lamp family. Typical applications include panel indicators on industrial machinery, control stations, and safety interlocks, where durable LED illumination provides long life and reliable visibility in harsh environments. When selecting a replacement, ensure you choose the N77R variant to produce red illumination, as the 800T family includes other LED lamp variants for different voltages and mounting options. For compatibility, source a genuine Allen-Bradley accessory to match your 800T installation, and verify whether your application uses a transformer LED (PCL) or full-voltage LED (QCL) configuration within the 800T cluster pilot light ecosystem.
