# Interior Lighting Design

## When to use this skill
Use when the user says things like:
- "help me design interior lighting"
- "plan layered lighting for a room"
- "choose color temperature for living spaces"
- "integrate dimmers and scenes"
- "maximize daylight and minimize glare"


## Core Philosophy

Lighting is the most transformative element in interior design — it shapes how every other
design decision is perceived. A beautifully furnished room with poor lighting feels flat and
uninviting; a simple room with excellent lighting feels warm and alive. Good lighting design
layers multiple light sources to support different activities, create depth, and establish mood.

## Key Techniques

- **Three-layer approach**: Combine ambient (general), task (focused), and accent (decorative) lighting in every room.
- **Color temperature selection**: Choose warm (2700-3000K) for living spaces, neutral (3500-4000K) for kitchens and baths, cool (4000K+) for workspaces.
- **Dimmer integration**: Install dimmers on all ambient and accent lighting for mood and energy flexibility.
- **Focal point illumination**: Use accent lighting to highlight art, architectural features, and design elements.
- **Natural light optimization**: Maximize daylight through window treatment selection and reflective surfaces.
- **Circadian-aware design**: Support natural sleep-wake cycles with tunable or warm evening lighting.

## Best Practices

1. Plan lighting during the floor plan phase, not after construction. Electrical rough-in is expensive to change.
2. Use multiple light sources in every room — a single overhead fixture creates flat, unflattering light.
3. Place task lighting where work happens — reading chairs, kitchen counters, bathroom mirrors.
4. Hide light sources when possible. Seeing the bulb usually means the design could be better.
5. Use consistent color temperature within a room for visual coherence.
6. Light vertical surfaces — walls and art — to make rooms feel larger and more three-dimensional.
7. Consider lighting controls (scenes, timers, occupancy sensors) for convenience and energy savings.

## Common Patterns

- **Cove lighting**: Indirect light from ceiling or wall coves for soft ambient glow.
- **Under-cabinet task lighting**: Direct illumination of kitchen and bathroom work surfaces.
- **Picture lighting**: Dedicated fixtures that draw attention to art and create gallery effect.
- **Floor wash**: Recessed adjustable fixtures that graze walls with light, adding texture.

## Anti-Patterns

- Relying on a single ceiling fixture as the room's only light source.
- Mixing warm and cool color temperatures in the same room unintentionally.
- Over-lighting with excessive recessed cans in a grid pattern.
- Ignoring glare control — visible bulbs reflecting in screens and mirrors.
