In short
- A scene stores a level for every lighting role in a room and recalls them together. It is how a layered design survives daily use.
- Most homes need five to seven scenes, not twenty. Each scene should answer one moment of the day.
- Write the scene matrix on the lighting schedule at design stage. It decides circuiting, keypads and commissioning.
Why scenes, not switches
A living room with an accent, a cove, a wall wash, downlights and pendants has five control channels. Five dimmers on a wall are not used; the household finds one combination that works and leaves it there, usually everything on.
A scene replaces that with one press: “Evening”. It is the difference between a design that is lit once at handover and one that is lived in. The circuiting that makes this possible is covered in Lighting Controls for Architects.
The scene matrix
Levels are percentages of each role’s maximum. They are starting points for commissioning, not fixed values.
| Scene | Accent | Architectural | Task | Ambient | Decorative | Purpose |
|---|---|---|---|---|---|---|
| Morning | 0 | 40 | 80 | 70 | 0 | Bright, practical, cooler if tunable |
| Day | 0 | 20 | 0 | 0–20 | 0 | Support daylight in deep plans only |
| Evening | 40 | 70 | 0 | 20 | 60 | The scene the design is judged by |
| Entertaining | 80 | 90 | 30 | 50 | 80 | Generous, all layers visible |
| Puja | 60 on shrine | 15 | 0 | 0 | 0 | Focus on the deity; diya leads |
| Cinema | 0 | 5 | 0 | 0 | 0 | Bias light behind screen, floor path |
| Night path | 0 | 0 | 0 | 0 | 0 | Low-level path to bathroom or kitchen at 1–5% |
The evening scene deserves the most commissioning time. It is the hour clients judge the house by, and the hour visitors see.
Rules for scenes that get used
Fewer scenes, named for moments
- Five to seven scenes per main room. More are forgotten.
- Name them for what happens, not for levels: “Evening”, “Guests”, “Puja”, not “Scene 3” or “50%”.
- Keep Off on every keypad, in the same position.
Same scene, same place
- The same scene sits in the same button position on every keypad in the house.
- Household staff, guests and grandparents should be able to use any room without instructions.
Fade, do not snap
- Transitions of 2–5 seconds between scenes feel deliberate. Instant changes feel like a fault.
- Night path and “All off” can be faster.
Override without breaking
- A raise/lower on the keypad should adjust the whole scene proportionally.
- Returning to the scene should restore the commissioned levels.
The Indian household
Puja
- The puja scene is often the most personal. It lowers the room and focuses on the shrine, then gives way to the diya during aarti. Detailed in Lighting the Puja Room.
- Morning and evening prayer times can be scheduled, with a manual override.
Large families and staff
- More people use the house, often at different hours. Scenes protect the design from being overridden by whoever reaches the switch first.
- Service areas should stay on simple switching or sensors. Not every room needs scenes.
Festivals
- Diwali, weddings and family gatherings call for a “Festival” or “Guests” scene with exterior and facade light included.
- Link exterior scenes to an astronomical clock so they follow sunset through the year. See The Night Image.
Power backup
- Decide which channels stay on inverter or DG supply. A reduced “Backup” scene keeps architectural and path light, not every accent.
Voice and app
- Voice works when it maps to scene names: “Evening”, “Puja”, “Good night”. It fails when users must remember channel names.
- Hindi and regional-language commands are practical for many households. See Voice Control.
- Apps are useful for schedules and adjustments, but keypads remain the primary interface.
Commissioning
- Set scenes on site, at night, with the client present for the evening scene.
- Record final levels on the as-built lighting schedule.
- Revisit after a month of occupation; most households refine two or three scenes.
- Check the low end: scenes below 10% expose drivers that step or flicker. See Dimming Quality.
Specification notes
- Include a scene matrix (levels per role) for each main room on the lighting schedule.
- Limit main rooms to five to seven named scenes, plus Off.
- Keep scene positions identical on every keypad.
- Specify fade times (2–5 s) and proportional raise/lower.
- Define a reduced backup scene and an astronomical exterior schedule.
- Commission at night, and revisit after occupation.
Frequently asked questions
How many lighting scenes does a room need?
Most living rooms work well with five to seven: morning, evening, entertaining, a special scene such as puja or cinema, night path and off. More than that is rarely used.
Can scenes control curtains and AC too?
Yes, if the control system integrates them. A “Cinema” scene can close curtains and dim lights together. Keep lighting scenes usable even if the integrated systems are offline.
Should scenes be set before or after handover?
Both. Define the matrix at design stage so circuiting supports it, commission levels on site at night, then refine after a few weeks of occupation.
