What a Stage Lighting Plan Covers: Rigging, Colour Temperature and Power

Why we are writing about lighting plans now

As the evenings draw in, studios and small stages across the country start planning their winter schedules, and lighting is often the item that gets looked at last. Enquiries to our Stage Lighting Design Advice service tend to rise in these weeks, so it seems a sensible moment to set out plainly what the service involves and what a client receives at the end of it.

I coordinate those enquiries, so much of what follows comes from the first conversations I have with studio managers and production engineers. Most of them are not asking for a grand design. They want to know whether their existing fixtures suit a new set, whether the ceiling can take another bar, or why one camera sees skin tones differently from another.

This article covers the advice itself: what we look at, what we write down and what we leave to you or your electrician.

Starting with the room and the set

Every plan begins with the space. We ask for a floor plan or a set of simple measurements: ceiling height, the position of any grid or truss, the distance from the set to the nearest power distribution and the size of the playing area. Photographs of the room from two or three corners help a great deal, especially where pipework or air handling sits lower than expected.

We also ask what the production is. A talk programme with two presenters and a fixed desk needs a different approach from a live stage with moving performers, and a corporate studio recording short pieces to camera has different priorities again. Knowing the number of cameras and where they stand tells us which angles the light must serve.

From this we agree a brief for the plan, in writing, so that everyone shares the same picture before any recommendation is made.

• Floor plan or measurements of the room
• Photographs showing the ceiling and any obstructions
• Number and position of cameras
• Type of production and how often it records

Rigging: where the weight goes

Rigging is the part of a lighting plan that clients most often underestimate. A fixture has to hang somewhere, and the bar, grid or stand carrying it has a safe working load that must not be exceeded. Our advice sets out where bars should sit, how many fixtures each can reasonably carry and how cables should be dressed so they do not pull on a lamp or drop into shot.

We recommend positions in relation to the camera shots you actually use. Key and fill lights need enough throw distance to feel soft, and backlights need height so they do not appear in a wide frame. Where a ceiling cannot take additional load, we describe alternatives such as floor stands or wall brackets.

We do not certify structures. If a plan asks a ceiling to carry more than it carries today, we say so clearly and recommend that a qualified person inspects it first.

Colour temperature and keeping the picture consistent

Colour temperature is the setting that decides whether faces look natural or slightly orange or blue on screen. The plan states a target for the set, usually a single value, and lists which fixtures can reach it. Mixing daylight-balanced and warm fixtures without a plan is the usual cause of a picture that shifts between shots.

Windows are the common complication. Daylight changes through the day and through the season, and in autumn it fades early. We advise whether to block it, balance it or use it as part of the look, and we note where cameras should be white balanced against a reference.

Where a studio uses LED fixtures with adjustable colour, we write down recommended settings for each scene so that operators repeat the same look from one recording to the next, whoever is on shift.

• One stated colour temperature target for the set
• Notes on window light and how to control it
• Recommended fixture settings recorded per scene

Power needs and what the electrician still decides

A lighting plan is only usable if the supply can feed it. We add up the load of the fixtures in the plan and compare it with the circuits you tell us are available, then flag where the total looks too high or where dimmer and control equipment will need its own supply. LED fixtures draw far less than older tungsten units, which often changes the answer.

We set out how fixtures might be grouped across circuits so that a single trip does not darken the whole set, and we suggest where distribution points should sit to keep cable runs short and tidy.

Electrical installation and testing remain the work of a qualified electrician. Our figures are a planning aid, and we say plainly where your own installer should confirm what the building can deliver.

What you receive and how to ask

The result is a written plan: a lighting layout drawing, a fixture list, rigging notes, colour temperature targets and a power summary, with short explanations so that a new member of the crew can follow it. We aim to write it in plain language rather than a catalogue of specifications.

Most plans are completed after a short exchange of measurements and photographs, and a visit is added only where the room cannot be understood from a distance. Costs are set out on the prices page and confirmed in a written quotation before any work starts.
