Event lighting: stage, venue, audience and cameras

Give each lighting position a task

Mark where each participant speaks, plays, or moves and where the audience will be. Then assign tasks: show faces and actions, separate from the background, add color, highlight a product, and follow the rhythm. A fixture can do more than one if its position and optics work. Note when its task changes so it can be rehearsed.

Front, side, back, and top light describe positions relative to the person, not fixture names. ETC explains how these angles change visibility and shadows. Backlight helps separate a figure from the background; steep overhead light may leave eyes and mouth in shadow. ETC: lighting angles.

For a talk, start with the lectern and speaker’s route. For a band, draw positions, instruments, and solos. With tables, add ambience and service moments. Identify on the plan which lights serve the stage and which serve other zones so each task can be reviewed separately.

Compare profile, Fresnel, wash, moving lights and battery fixtures

Review what each type can do and complete the choice with optics, accessories, and model. ETC distinguishes soft-edged Fresnels, profiles with shutters and gobo projection, and moving spot or wash lights. ETC: fixture types.

Uplighting illuminates walls, columns, or other elements from below. When comparing battery fixtures, request runtime in the mode you will use, charging, and control. WELL Fit X, for example, offers 5, 8, 12, and 18-hour selections and compatible wireless control. These are that product’s options; review those of the offered uplight. Chauvet: WELL Fit X.

Tell the supplier the effect you want and how long it will stay on, including rehearsal and standby. Batteries may reduce cable runs at those positions; include preparation, charging, and operation too. Confirm model and availability when reviewing the proposal.

Measure throw and review photometrics

Throw is the distance from fixture to target; beam angle is the cone’s angle. Moving a fixture changes the area it covers. Draw size, incidence, and overlaps, and check light falling outside the zone.

The model’s photometrics let you compare distribution and level at specific distances. ARRI offers a tool with beam diameter and angle, light distribution, and exposure data. Use the optics and configuration that will actually be installed. ARRI: Photometrics.

To understand the geometry: an ideal 26° cone on a perpendicular plane, 10 m from its origin, has a diameter of about 4.62 m: 2×10×tan(13°). This calculation does not provide lux, uniformity, shadows, or useful coverage on a tilted surface. Supplement it with a plan, photometric data sheet, and model test.

Review the angles the site allows instead of treating 45° as a rule. In a low hotel room, an almost horizontal position can change shadows or cause glare. In a theater, a high distant position may need different optics. View those options from audience and participant positions before finalizing the plan.

Eight inventories to start the comparison

These quantities are original proposals for the programs and areas in the table. To choose them, review positions, model, and photometrics; attendance does not turn a row into a package. Prepare supports, distribution, control, and work, circulation, and emergency lighting separately.

In the table, front light means illuminating participants. Choose profile, Fresnel, or another option based on throw and beam control. Add optional variants when they serve the program and check their effects on space and operation.

At conferences and hotels, test faces and room lighting

Prepare looks for arrival, welcome, presentation, panel, questions, break, and departure. Have the speaker walk away from the lectern and check that they remain lit. Seat the panelists and view every face, including the ends, with shadows from lecterns, tables, and other people.

Record clear ceiling height, chandeliers, reflective walls, and access points. With the hotel operator, review which room zones you can dim and how they coordinate with the console. Draw presentation, reception, and dinner by zone. The example’s eight uplights are eight selected accents; they do not represent eight tables or a guest ratio.

Assign a zone and look for products, awards, and photos. You can use color on backgrounds and architecture while reviewing presenters’ faces separately. Test graphics and exposure with someone in position before setting ambient intensity.

Plan changes with musicians, DJ and host

Draw the layout for lead vocal, backing vocals, instruments, drums, and movement. Include risers and zones that change between artists. For the five-piece band, we compare ten fixtures and the sixteen-fixture variant. Raised drums, a large keyboard, or moving musicians may need different focus: test them in their actual positions.

A cue is a programmed look or change. Prepare introduction, songs, solos, breaks, and closing. Agree on whether the operator follows the musician or a sequence. Give movement, gobos, and color a moment in the program; this helps decide why each fixture is added.

For a DJ, separate booth, host, and dance floor. At a standing concert, review the stage front and assistance points. If lighting the audience, test focus from their positions to avoid glare for those staying there. Agree on the extent and communication of flashing effects with production and venue teams.

Plan for reading, dining and circulation too

Draw reception, tables, bars, dance floor, aisles, level changes, restrooms, and exit. Note what people must do in each zone: read, eat, talk, or move. Coordinate accents and effects with the light those tasks need.

Agree on how far ambient light dims during the presentation and retain the intended function of routes and emergency lighting. HSE recommends lighting escape routes, avoiding fixtures that cause glare along them, and providing independent power in case of failure. Use that British reference to review the plan with the venue and responsible parties according to local requirements. HSE: lighting and evacuation.

Define who requests exit lighting, how an interruption is communicated, and what maintains emergency functions. A look on the show console does not by itself provide that system. Before opening, walk routes and test audience looks with the person receiving the venue.

Use the table to review zones and moments. Separate seeing, reading, dining, and circulation from show effects, and assign who operates arrival, performance, break, and departure. Indoors, coordinate the room system; outdoors, include changing daylight and areas away from the stage. Choose quantities by surface area, height, optics, distribution, and task instead of copying stage lighting.

Test cameras, LED screens and color together

CCT, correlated color temperature, describes the appearance of white light and is expressed in kelvin. Two fixtures with the same nominal CCT can differ in tint; ETC explains why green/magenta deviation may matter too. ETC: whites and CCT.

Use the event’s cameras, fps, shutter settings, and looks, including at low intensities. ARRI distinguishes audience and camera settings: SkyPanel Classic Stage Mode is not intended for cameras, and some high-speed modes have dimming limits. Review the model before transferring a mode name to another brand. ARRI: SkyPanel Classic FAQ.

Flicker may appear as pulsation or bands in the image even when light looks steady to the eye. If you change a compatible fixture or camera setting, retest the complete setup. For flicker related to DMX control, follow the flickering LED lights guide.

With LED screens, test brightness and content together with faces, clothing, and camera. Review reflections, shadows, light backgrounds, and spill onto the screen. Test actual images and cue changes; raising every brightness level does not show the final relationship between face and background.

Outdoors, review complete equipment and connections

Record ambient light, ground, wind, water, and routes. Test at the event’s scheduled times: daytime installation, dusk opening, and nighttime show may need different looks. Agree on supports and operating limits with the structures lead and venue.

Find the model’s IP rating and instructions. For Ovation E-260WW IP, Chauvet requires outdoor power and data cables rated IP65 or higher, protected caps on unused ports, and compliance with its operating limits; immersion is prohibited. Review those connections: the fixture’s IP65 does not describe the entire installation. Chauvet: Ovation IP guide.

ARRI identifies SkyPanel Classic as IP20 and requires protection from rain or snow while maintaining ventilation. Confirm that condition for that family; other equipment from the brand may have another rating. ARRI: SkyPanel Classic protection.

Ask the proposal to include protection, connections, and decisions for changing weather. Review covers, tents, and IP ratings by function and confirm how they work together before the event.

Make patch, modes and addresses match

Patch connects what you select on the console with what each device controls. Record manufacturer, model, mode, universe, and address. Review the mode’s channel footprint and each channel’s function with the fixture profiles and DMX modes guide.

A DMX512 universe has 512 channels. In our assumed-mode example, six front lights at 8 use 48; four washes at 8 use another 32; four moving lights at 24 use 96; two floor washes at 8 use 16. That is 192 channels and fits in one universe if addresses do not overlap. Recalculate with the actual modes. ENTTEC: DMX universe.

Art-Net and sACN carry control over a network. Review what devices receive and what the design’s gateways convert. ENTTEC documents protocols and synchronization; if using multiple sources, configure how they are selected or merged. On its sACN products, priority applies per universe. ENTTEC: output protocols, ENTTEC: source merging.

Check lines, distribution, termination, and compatibility before programming. ETC describes intermittent faults caused by cabling and termination. Save the show and test a fixed look, transitions, and intended behavior on losing a source. ETC: DMX troubleshooting.

Agree on power, supports and haze before loading

Gather model, quantity, and power consumption of lights and controls, plus the event’s other systems. With the electrical lead, confirm supply, distribution, and routes. HSE includes site, grounding, isolation, and emergency needs in electrical planning. Review local application with project leads. HSE: event electricity.

Draw each light’s position and support using actual weights and accessories. Ovation IP requires appropriate clamps and secondary retention for elevated installation. Ask the structure design to address loads and stability for its configuration: a fixture’s instructions do not calculate a tower or truss. Chauvet: equipment mounting.

Use haze if it serves the design and the venue allows it. Rosco recommends the minimum needed and fluid compatible with the machine. Identify machine and fluid, read their documents, and agree on dispersion, ventilation, and detection with the venue before bringing it. Rosco: V-Hazer.

Prepare installation and test the complete event

Allow time for preparation, installation, focus, patch review, programming, rehearsal, operation, and removal. Agree on access, crew, venue contacts, and artist contributions. Calculate from equipment, heights, doors, and program changes; attendance does not determine installation time.

Send us date, venue, plan, ceiling, program, positions, and audience zones. Add cameras and intended settings, screen, ambient light, indoor or outdoor conditions, schedule, power, and visual references. This lets us compare functions, inventory, and operation without relying only on a photo.

1. Finalize program and areas

   Place participants, routes, audience, furniture, cameras, screen, and event moments.

2. Measure the venue

   Record throws, heights, available positions, access points, and room systems. Outdoors, include conditions and schedule.

3. Prepare plan and inventory

   Assign functions, models, optics, positions, supports, and connections. Agree on who provides each part.

4. Coordinate power and structures

   Confirm distribution, cable runs, supports, and responsible parties using actual equipment data.

5. Install and focus

   Follow each system’s procedures. Check positions and that the beam reaches the intended zone.

6. Check patch and control

   Test modes, addresses, universes, lines, and functions before expanding the configuration.

7. Rehearse cameras and cues

   Review people, shadows, backgrounds, and LED screens. Test looks, changes, and audience states with actual equipment.

8. Agree on handover, operation and removal

   Define responsible parties, preserve venue functions, and coordinate closing, de-energizing, and dismantling.

Uplighting: agree on the wall’s appearance first

A quote with more uplights may be proposing a different look for the room. Before comparing quantities, ask each supplier to show the goal: separate columns, accents on venue features, or continuous color across fabric. A shared visual reference lets you discuss the same proposal.

For Freedom Par Hex-4, Chauvet publishes a 23° beam angle and 34° field angle. Those figures alone do not determine the unit count: fabric height, fixture positions, and the finish you want to approve are still needed.

Request a sample span with the actual fabric. View it from a table, from the sides, and with the other planned lighting on. For continuity, pay particular attention to gaps between fixtures and the top edge; for columns, agree on their positions.

With that sample approved, request a plan showing positions and areas included in the price. Review doors, corners, and circulation zones with the venue lead. Quantity comes from that scope; comparing only the total fixture count leaves too many differences unresolved.

Programmed runtime: compare brightness at the same runtime

If the catalog advertises up to twenty hours, ask to see the look at the runtime your program needs. Record runtime and intensity separately. A fixture at one hundred percent may have a different output limit from the one in a shorter demonstration.

As a specific reference, Astera’s AX1 Technical Reference manual, dated 25 August 2020, explains that the tube adjusts power to the requested runtime and calculates it from a full battery. That setting must accompany brightness comparisons.

Build the schedule from first switch-on to the last moment that light is needed. If there is standby time, ask how it will be operated then. Compare important looks at the chosen runtime with the fixtures that will be supplied for the event.

Ask the supplier to review the batch’s condition and agree on charging, control, and backup units. Save the approved model, runtime, and level with the look. If program duration later changes, repeat the comparison before retaining the same fixture count.

Separate beam edge from field uniformity

If a profile leaves one area very bright and another weak, ask for a field review before adding fixtures to compensate. Identify the model: “Leko” is used for different equipment.

On the Source Four HPL documented in ETC’s Rev C manual, rear lamp adjustment separates centering and field; the lens tube controls edge focus. These are different checks. Ask the technician to review them following the manual for the equipment.

Then view the scene with people in their actual positions. Mark where the variation starts and which change was made. A softer edge may be part of the design, but the comparison must include the faces you need to light.

For several days, agree on how each uplight is powered

For a multi-day conference, build the complete schedule: installation, reception, performance, standby, and next opening. Agree on whether fixtures stay connected, are removed, or charge between days. Wireless control does not answer how each unit will be powered.

The AX5 TriplePAR manual from 2020 distinguishes wired operation with bypass from charging. It is designed to charge while off; when on, it may charge at lower current depending on temperature and available power. Confirm status before the next day.

Ask the supplier for the operating and charging sequence for the batch to be supplied. Note who checks status before opening and how each fixture is accessed. If the schedule changes, review the plan; retaining the quantity that worked at a short reception is not enough.

Define the edge you want before requesting an iris

For a lectern or stationary person, mark the area to be lit. For a panel, add the boundary to respect and where light must not fall. Showing both to the operator is more useful than requesting a tighter spotlight.

Source Four HPL shapes its beam with four shutters and accepts a circular-aperture iris in a separate slot. Confirm the accessory for that body and test the cut.

Review the result with lectern, scenery, and person in their actual positions. Take a reference from the camera or audience position. If the presenter’s position changes, review the edge again before treating the look as finished.
