Key Takeaways
- Colour temperature (warm vs cool white) is the most impactful lighting decision for photography — match the colour temperature to the brand's visual identity
- A venue's house lights are almost never adequate as the primary conference lighting — supplementation is needed for photography, speaker presentation and programme mood
- Moving lights (automated fixtures that can pan, tilt and change colour/gobos) are the most versatile investment for produced events but require pre-programming time
- The DMX protocol controls virtually all professional stage lighting — the lighting designer needs to know the venue's existing DMX infrastructure before specifying
- LED technology has largely replaced tungsten in Indian rental markets — LED is cooler, more energy-efficient and more colour-stable, but the quality of LED fixtures varies enormously
The three lighting states every event needs
Working state: The ambient level for when the room is in session but the speaker is the focus — tables lit enough to take notes, stage lit to a consistent, photographable level, aisles lit for safe movement. Colour temperature: 3,000–3,500K (warm white). This is the state the event spends 80% of its time in and the state that most productions leave to the venue's house lights. It should not be — the venue's house lights are typically too bright for the stage to read as a produced element against them.
Presentation state: Used when a video presentation, product reveal or entertainment element requires the room's ambient light to be reduced so the screen content reads clearly. The audience area dims to 15–20% of working state; the stage lights hold or intensify to maintain the speaker's visibility against the darker ambient. This state requires the lighting designer to pre-programme the room's response to the screen's content.
Networking/break state: Higher ambient, warmer, more even distribution, stage lighting relaxed. This is the state that communicates "the formal programme is on pause — move, talk, use your phones." A sharp transition from presentation state to a well-designed break state does as much work as the MC's announcement that there's a coffee break.
Fixture types and their uses
Fresnel: A classic tungsten or LED wash fixture with a soft-edged beam. Used for stage key light and fill, and for even ambient area illumination. Reliable, predictable, inexpensive to hire. Profile (Leko): A hard-edged fixture that can be focused to a precise shape — used for key light where precise positioning is critical, for gobos (projected texture patterns), and for accent lighting. Moving light (automated head): A motorised fixture that can pan, tilt, and change colour, intensity and beam shape under DMX control. Used for dynamic state changes, colour washes, beam effects and entertainment lighting. LED batten/strip: A low-profile LED fixture used for set piece illumination, backwall colour wash and under-stage lighting.
What to ask a lighting designer
Before approving a lighting brief: What are the three lighting states for this event, and what instruments and positions achieve each? What DMX console will be used, and is it compatible with the venue's existing infrastructure? What is the dimmer configuration, and does it support the LED fixtures you are specifying? What pre-programming time does the rig require, and is that time allocated in the load-in schedule? What is the power draw of the full rig, and does the venue's power supply support it? A lighting designer who cannot answer these questions in the briefing meeting will not produce them on load-in day.
