Place the ladder under the grid so that climbing the ladder will allow you to reach the bar you wish to hang the light on. Ensure the light is in good condition and has a safety wire.
Carefully climb the ladder with the light. Attach the light's C-clamp to the grid and tighten until secure by turning the bolt clockwise. Once the light is stable, attach the safety wire to the grid by unlocking it, fitting it around the grid bar and locking it. Use the wrench to firmly lock the bolt and light into place.
Plug in the light by plugging the light cable into a cable in the lighting plot. To further secure the connection, one can tape the plugs together with Gaft (or gaffer's) tape.
Climb down and repeat with the next light. Once all the lights are hung, you can progress to programming the light boards and focusing the lights.
