Lighting Design: A Checklist to Work Through Before You Commit

The first item on any lighting checklist is the space itself, and it is the one most often skipped. Before a fixture list exists, someone should stand in the studio with a tape measure and write down the ceiling height, the clear depth from the grid to the floor, and the loads the structure can carry. A rig that looks sensible on paper can fall apart when the grid sits too low for the throw distances the key lights need, or when ductwork and sprinkler pipes sit exactly where a bar was meant to go.

It is worth asking at this stage how the room will be used over the next few years, not just for the first production. A studio that hosts a single news set today may host a talk show with three playing areas next autumn. A grid that allows rearrangement is cheaper than one that must be rebuilt, and it costs very little to leave spare bars and spare power at the planning stage.

Finally, record what the room does to light: wall and floor colour, reflective surfaces, and any daylight that reaches the set. These details shape how much power is wasted and how much spill you will fight later.

• Ceiling height and clear depth below the grid
• Structural loading and hanging points
• Existing ducts, pipes and sprinklers
• Wall, floor and daylight conditions

Lighting is judged through the lens, so the camera plan must be settled or at least sketched before the lighting is fixed. Ask which cameras are in use, what their sensitivity is, and what exposure the camera shaders expect to work at. A level that suits one camera family may leave another noisy or flat. Agreeing a target illumination on the key subject, and the contrast range between key and background, gives the whole team a number to design against rather than an impression.

Think about movement too. Presenters who walk between two positions need even coverage along the path, not two bright spots with a dim gap. Wide shots reveal every shadow on the cyclorama or backdrop, while tight close-ups punish a harsh key. Listing the shot types the director expects, from the widest establishing view to the closest interview framing, shows where the compromises will fall.

This is also the right moment to talk with whoever will run camera control, because their view of acceptable contrast often differs from the designer's.

• Camera models and the exposure level they work at
• Target key level and key-to-background contrast
• Shot types from widest to tightest
• Presenter movement paths across the set

Fixture selection is where budgets are won or lost, so it deserves a clear set of questions rather than a favourite brand. For each position on the plan, ask what the light has to do: soften a face, throw a hard edge onto a logo, wash a backdrop evenly, or add a practical accent. Soft sources, profile spots and wash lights each answer a different need, and a rig built mostly from one type will either be too flat or too fussy.

Weigh colour quality and the ability to match fixtures across the rig, because mixed output on screen is a problem no control desk can fully correct. Heat and fan noise matter in a studio where microphones sit close to the set, and so does the time needed to refocus or change a lamp on a busy day.

Count the real number of fixtures against what the room can power and cool. A shorter, well-chosen list nearly always beats a long one assembled to fill the grid.

• Purpose of each lighting position
• Colour quality and consistency between fixtures
• Fan noise near microphones
• Power and heat load against available supply

Control programming is easy to treat as an afterthought, yet it decides whether the rig is pleasant or painful to run. Ask who will operate the lighting on a normal show day and how much experience they have. A small crew may want a handful of clear presets and a simple way to adjust them, while a larger team can handle layered cue lists and detailed fixture control.

Check how each fixture is addressed and wired, and whether the numbering follows a pattern a newcomer could learn in an hour. Agree what happens when something fails: which circuits stay on, and what the fallback look is if the desk loses its show file. These are dull questions, and they are exactly the ones that matter at ten minutes to transmission.

Finally, decide how the lighting talks to the rest of the production. If cameras, graphics and sound are all being rearranged, a shared plan avoids surprises on the first rehearsal.

• Operator experience and number of operators
• Addressing pattern and patch documentation
• Fallback look if the desk or show file fails
• Link to the wider production plan

A lighting installation is only as good as the way it is maintained, so the checklist should include a plain question about ownership. Who changes lamps, who checks focus, and who keeps the patch list up to date when a fixture is moved? If the answer is nobody in particular, the rig will drift within a season, and the next production will inherit a set of labels that no longer match the grid.

Think also about handover. A written plan with fixture positions, circuit numbers and a few photographs of the rig as built saves hours for any new crew member. Short training sessions on the real desk, with the real show file, are more useful than a manual left on a shelf.

Ask for this documentation before the work is signed off, not after, because attention fades quickly once the studio is in use and the first live show is looming.

• Named person for lamp changes and focus checks
• As-built plan with positions and circuit numbers
• Hands-on session using the real desk
• Documentation requested before sign-off

The last part of the checklist joins everything above to time and money. Lighting work depends on other trades: a grid cannot be loaded until the ceiling work is finished, and focusing cannot start until the set is built. Ask for a sequence of tasks with the dependencies written down, so that a late delivery elsewhere does not quietly eat the days reserved for lighting.

On cost, separate what is bought once from what is paid for repeatedly. Fixtures, cabling and the desk are one-off items, while lamps, power and labour recur. A cheaper fixture that draws more power or needs frequent servicing can cost more over a few years than a better one bought at the start.

Leave a modest allowance for changes found during rehearsal. Nearly every studio finds something it did not expect, and a plan that admits this is easier to deliver than one that pretends otherwise.

• Task sequence with dependencies noted
• One-off costs separated from running costs
• Allowance for adjustments found in rehearsal
