Lighting Technician

What they do

A lighting technician spends the day physically making light happen. They run and dress cable, land it in distribution, set stands and hang units, and put a lamp exactly where the gaffer pointed, at the height and angle asked for, then adjust it on call: a quarter turn, two feet back, half intensity, a scrim in, a gel on the frame. They fit and swap diffusion and gels, set practical lamps and dimmers inside the set, tape down runs so the camera and boom can work over them, and take a lamp out cleanly when the reverse needs the space. On an LED-heavy show one technician usually runs the console, patching and programming fixtures over DMX and building the cues that a scene needs, which IATSE Local 728 recognises as a distinct classification. Working at height on a scaffold, a condor or a stage grid is part of the job, as is the physical care that keeps it safe: gloves for hot fixtures, safety cables on anything overhead, and knowing the load on a circuit before adding to it. In live entertainment the recognised certification route for the electrician's discipline is the Entertainment Technician Certification Program, which exists specifically for the disciplines that affect crew and performer safety.

What they decide

The calls that belong to this role and no other.

• How a specific fixture is rigged, secured and dressed once its position is called
• Cable routing and dressing, so it is safe and out of camera and boom paths
• Console patching and cue programming when working as board operator
• Whether a rig is safe to leave unattended or needs a second safety
• Flagging a circuit or a fixture that is being asked to do something it should not

Principles of the craft

• Safety is the first craft skill: a safety cable on an overhead unit, a tested circuit and a properly dressed run are not bureaucracy, they are the difference between a long career and an incident report.
• Precision beats speed on placement: a lamp two feet from where it was called for changes the shadow on a face, and the gaffer will be adjusting the wrong thing to compensate.
• Know the load: every fixture has a draw and every circuit has a limit, and adding one more head without doing the arithmetic is how a take is lost.
• Leave the set workable: cable routed where the dolly runs or the boom swings creates a problem for two other departments that will be blamed on lighting.
• Learn the console: on an LED show, colour and level are changed from a desk rather than at the lamp, and the technician who can patch and program is the one who shapes the day.

Common mistakes

• Rigging overhead without a secondary safety
• Guessing at load rather than calculating it, then tripping a circuit mid-take
• Placing a unit approximately and waiting to be corrected instead of setting it to the call
• Leaving gel or diffusion unsecured so it flaps and moves the light during the take
• The competent version: fast, clean rigging done without listening to what the setup is for, so the light is technically perfect and pointed at the wrong actor

How to learn it

Exercises and routes in, not a reading list.

• Rig one unit overhead correctly, with a proper safety, then have someone experienced try to find a fault in it. Repeat until they cannot.
• Take a single lamp and shoot a face at five positions: same distance, moving through frontal to a hard side to a three-quarter back. The exercise makes placement precision visible.
• Patch and program four LED fixtures on a console to run a two-cue scene, colour change included, and rehearse the change against dialogue timing.
• Calculate the draw of a small package on paper, then measure it with a clamp meter. Note where your arithmetic was wrong and why.
