St Josephs Cathedral Lighting Retrofitting Begins
The way that this system will work with the existing fixture is that the current fixture top, which looks like a hat, will be modified so that a box can be mounted on the top of the hat in order to house the generator, which is required to allow the lamps of the QL system to illuminate. All of the internal components of the current fixture, including the incandescent socket, miscellaneous hardware, and the custom alzak reflector will be removed. The only component that will remain of the original interior components of the top portinion of the fixture is the alzak reflector once the retrofit kit is installed by Grand Light. This reflector has to be modified to accept the custom heat sink which will connect to the power coupler of this QL system, which serves as the igniter for the QL system. The final internal component of this retrofit kit is the lamp, which connects to the power coupler.

Shown in this photograph is the retrofit kit unit that was used as a mock-up. You can see the box that is attached to the top of the hat, the original modified alzak reflector which is holding the power coupler, custom heat sink, lamp, and the original fixture body.
