The GE LightSweep Retrofit Kit for 48 Relay Legacy Panels (INT48-RET48) is designed to modernize existing GE Lighting Control panels by converting them from their original legacy TLC systems to the GE LightSweep modular control system. This retrofit approach allows facilities to extend the useful life of installed lighting infrastructure while transitioning to a modular, serviceable, and more flexible control architecture. Rather than requiring a full panel replacement, the retrofit kit enables a structured upgrade path that minimizes disruption and reduces the need for extensive rewiring.
The INT48-RET48 retrofit kit provides the mechanical adapter hardware required to install LightSweep modular components into a 48-relay legacy panel enclosure. These adapter plates and mounting accessories are engineered to align with the existing panel layout, allowing the new modular components to be securely mounted while maintaining proper spacing and organization. This approach helps preserve the original enclosure and relay layout, which is especially valuable in large installations where panel replacement would be costly, time-consuming, or operationally disruptive.
The retrofit kit consists of the following components, which together support the physical integration of LightSweep relay and group switch modules into a 48-relay legacy panel:
- 4x Relay Module Adapter Plates
- 1x Group Switch Module Adapter Plate
- 2x Tub adapter plates
- 28x screws
- 28x lock washers
- 4x long jumpers
The INT48-RET48 is intended to provide the structural and mounting framework required for the LightSweep system. The adapter plates ensure that relay modules and group switch modules are correctly positioned within the panel, while the supplied hardware supports secure installation and long-term mechanical stability. The inclusion of jumpers allows for proper electrical continuity as required by the modular configuration, without altering the original field wiring outside the panel.
It is important to note that the INT48-RET48 retrofit kit supplies only the retrofit hardware. Group Switch Modules and Relay Control Modules are required for system operation but are not included in the retrofit kit itself. These modules are selected based on the specific control and input requirements of the installation and are provided separately. For a 48-relay configuration, a Group Switch Module is required, along with Relay Control Modules sized to support the total number of relays in the panel.
The following LightSweep modules are compatible with the retrofit kit and are available separately to complete the system configuration:
By combining the INT48-RET48 retrofit kit with the appropriate LightSweep control modules, legacy GE lighting panels can be transitioned to a modular control platform that supports easier maintenance, phased upgrades, and improved long-term serviceability. This retrofit strategy allows facility owners and integrators to modernize lighting control systems while preserving existing investments and maintaining continuity of operation during the upgrade process.
