Fundamentals of Architectural Lighting
📌 Good lighting design balances three primary types of light: ambient, task, and accent lighting, tailored to the needs of specific spaces.
💡 Architects use light to evoke human emotion, define the scale and mood of spaces, and ensure functionality.
👁️ Human sight is the dominant sense, with an evolved awareness of light levels connected to emotional responses.

Design Strategies and Techniques
🤫 Hiding the light source (e.g., via skylights or clerestory windows) emphasizes architectural form and adds mystery, extending the perceived space.
✨ Employing irregular spacing of light sources can conjure movement and encourage informal gathering, but must be used sparingly against a backdrop of regular lighting to avoid chaos.
🎭 Utilizing dramatic contrast (theatrical treatment) establishes importance, guides people, and creates strong emotional connections, such as feelings of quiet reverence.
☀️ Daylight is superior as it is full-spectrum light; positioning openings higher admits light deeper into the space. North-facing windows offer diffuse, blue-toned light, while South/West offer warmer, high-contrast light.

Layering and Fixture Selection
3️⃣ Successful concepts often use the Rule of Three, layering ambient, task, and accent lighting in differing proportions to achieve professional results.
🔩 Don't be afraid to use bold groupings of multiple fixtures to anchor spaces by defining an overhead plane and creating an implied space through pooled light.
🎨 Recessed lighting trim choice matters: darker trims emphasize geometry and reduce glare on white ceilings, while white trims blend in.
🔮 Pair any translucent material with a light source to create unique elements, such as a backlit resin panel with embedded grass.

Practical Considerations and Calculations
📐 As a rough guide for calculating required wattage, multiply the square footage of the space by 1.5 to estimate total wattage needed.
💡 When selecting CFL or LED fixtures, check the incandescent equivalent wattage; the rated wattage measures electricity used, not light output (e.g., a 13-watt CFL equals a 60-watt incandescent).
📉 Use dimmers on every circuit if possible to control light levels and compensate for over-lamping (using a bulb with too high a wattage).
🔳 Consider square recess light trims in square-edged spaces for a more custom, integrated look, or even trimless options for a completely flush appearance.

Exterior and Specialized Lighting
⚫ To prevent large windows from appearing as black planes at night, light the exterior areas visible from inside; recessed soffit lighting focused on the ground often suffices.
💡 The Bare Bulb can be celebrated, especially where omnidirectional light is essential, like in bathrooms; consider sculptural CFL bulbs like those made by Plumen.
🖼️ Employ Museum Lighting (typically halogen) for a custom sparkle effect, using it to wash walls of reclaimed wood or stacked stone.
➡️ Lead with light by using embedded linear fixtures to draw lines toward destinations like an entry point, making the structure "alive" at night.

Key Points & Insights
➡️ Good lighting balances ambient, task, and accent layers, adapting to the space's function and mood.
➡️ Utilize hidden light sources to create depth, mystery, and emphasize architectural form.
➡️ When calculating lighting needs, use the square footage $\times$ 1.5 rule as a starting point for total wattage.
➡️ Always install dimmers to maximize control over light levels and mitigate potential over-lamping issues.
