Before attempting to carry out any rigging you should undertake the relevant training first and complete the working at heights training.
Lanterns are hung only on lighting bars using clamps. Check these are locked firmly onto the bars and that a safety chain is used for additional security.
Lanterns can also be supported on lighting stands, attached by spigots instead of clamps.
Make sure that any stand is on a level surface; on a tripod stand make sure the legs are as wide apart as possible and locked off correctly.
Lanterns can also be fitted to booms. These booms should be firmly fixed to the lighting grid and where possible secured to the stage using a suitable fixing.
Hanging a Lantern
The procedure for hanging a lantern is the same wherever you hang it, as follows:
- Hang each lantern in place (make sure it's not upside down!), lock the clamp to the bar and secure the safety chain;
- Point the lantern roughly in the right direction. This helps with focusing and may reveal problems such as overcrowding on the bar or bad sight lines;
- Put in the gel frame and barn doors if needed;
- Plug the lantern in making note of the socket number;
- Note: don't tape, knot or tie a lantern's power lead to a bar or boom. The cable should be left slack to allow for movement during the focussing process;
- Finally, ensure the plug corresponding to the socket number is plugged into a channel on the dimmer rack.
Operating a Lighting Desk
As all our performance spaces have lighting desks which are programmed in slightly different ways, specific training is needed for each one; speak with one of the technicians about taking the training.
Once you know how to use the desk ensure that a) the correct power source is fitted, and b) the DMX route to the dimmers is complete.
Ask one of the Technicians if you're unsure about anything.
