The Ultimate Interior Lighting Design Guide

Updated: Apr 19

Lighting plays a critical role in interior design, influencing the ambiance, functionality, and aesthetics of a space. Here's a general guide and design tips on different types of light fixtures and how they can be used in various types of rooms:


Design in Layers:

Lighting in interior design is often approached in layers to create a well-balanced and functional environment. These layers consist of ambient lighting, accent lighting, and task lighting. Each layer serves a specific purpose and when combined effectively, they can enhance the overall aesthetics and functionality of a space.


1. Ambient Lighting: Ambient lighting, also known as general lighting, provides the overall illumination for a room. It's the base layer of lighting that ensures the space is well-lit and comfortable for basic activities. Ambient lighting creates a soft, diffused glow that eliminates harsh shadows and fills the room with a comfortable level of light. This layer sets the tone for the entire space.


Examples of ambient lighting sources include:

  • Overhead fixtures like chandeliers, ceiling flush mounts, and pendant lights.

  • Recessed lighting that spreads light across the ceiling and bounces it off walls.

  • Natural light from windows and doors.


2. Accent Lighting: Accent lighting is used to highlight and draw attention to specific objects, areas, or architectural features within a room. It adds a sense of drama and visual interest by creating contrasts in brightness. This layer adds depth to the space and can help create focal points.


Examples of accent lighting sources include:

  • Track lights or adjustable spotlights aimed at artwork, sculptures, or decorative elements.

  • Wall sconces that highlight textured walls or artworks.

  • Display lights in cabinets or shelves to showcase collectibles.


3. Task Lighting: Task lighting is designed to provide focused, localized light for specific activities or tasks that require more illumination. It helps reduce eyestrain and ensures that activities like reading, cooking, or working are performed comfortably and without shadows.


Examples of task lighting sources include:

  • Desk lamps for reading or working at a desk.

  • Under-cabinet lighting in kitchens for better visibility while cooking.

  • Pendant lights or adjustable floor lamps for reading nooks.


By combining ambient, accent, and task lighting, a dynamic and inviting atmosphere is created. Each layer plays a distinct role: ambient lighting establishes an overall warm glow, accent lighting adds intrigue and visual interest to architectural elements or artwork, and task lighting ensures practicality for specific activities. This multi-dimensional approach adds depth and dimension to a room, preventing it from feeling flat or one-dimensional. Moreover, layered lighting provides remarkable flexibility to tailor the mood according to different occasions and preferences. Whether it's a cozy evening, a vibrant gathering, or a focused workspace, adjusting the intensity of each layer allows occupants to craft the desired ambiance effortlessly. Ultimately, layered lighting transforms a space from ordinary to extraordinary, enhancing its character and enriching the living experience.


 

Let's walk through each type of fixture, its appropriate use and placement, and some favorite selections:


Chandeliers:

  • Typically used in grand entryways, dining rooms, and formal living rooms.

  • Adds a touch of elegance and acts as a focal point.

  • Can be traditional, modern, or eclectic in style.

  • Placement Guidelines: Hang chandeliers above dining tables, ensuring there's at least 30 inches of space between the bottom of the fixture and the tabletop. In entryways, consider the ceiling height – for higher ceilings, the chandelier can be placed lower to create a dramatic effect.


Pendant Lights:

  • Great for over kitchen islands, dining tables, and reading nooks.

  • Provides direct task lighting while also contributing to the room's design.

  • Available in a wide range of styles and materials.

  • Placement Guidelines: Over kitchen islands and counters, position pendant lights about 30-36 inches above the surface to provide task lighting without obstructing views.



Ceiling Flush Mounts & Semi-Flush Mounts:

  • Suitable for general ambient lighting in hallways, bedrooms, and closets.

  • Ideal for spaces with lower ceilings where hanging fixtures might not work well.

  • Placement Guidelines: Install these fixtures in central areas of the room for even distribution of ambient light. Make sure there's sufficient space between the fixture and the ceiling.


Recessed Lighting:

  • Used for overall ambient lighting or task lighting in kitchens, bathrooms, and hallways.

  • Creates a clean and unobtrusive look, suitable for modern and minimalist designs.

  • Placement Guidelines: In general, space recessed lights evenly across the ceiling to avoid harsh shadows. For task lighting, place them directly above work surfaces. For ambient lighting, position them about 2-3 feet apart.




Track Lighting:

  • Used for directional and accent lighting.

  • Ideal for highlighting art, sculptures, or architectural features by directing focus light on specific areas.

  • Commonly used in galleries, kitchens, and retail spaces.

  • Offers flexibility as the individual fixtures can be adjusted along the track.

  • Placement Guidelines: Install track lights along architectural lines or beams to emphasize specific features. For task lighting, position them above work areas or artwork.



Wall Sconces:

  • Excellent for accent lighting in corridors, bathrooms, and bedrooms.

  • Adds visual interest and can be used to highlight artwork or architectural features.

  • Placement Guidelines: Mount wall sconces at eye level or slightly above (around 60-66 inches from the floor) for balanced lighting. Use them to frame mirrors or highlight architectural details.



Table Lamps:

  • Adds warmth and character to living rooms, bedrooms, and home offices.

  • Ideal for task lighting and creating cozy reading corners.

  • Available in a myriad of styles, sizes, and materials.

  • Placement Guidelines: Place table lamps on side tables or nightstands near seating areas. Make sure the bottom of the lampshade is at eye level when seated. Consider where your dedicated power sources are located.


Floor Lamps:

  • Provides ambient and task lighting in larger rooms or areas without overhead lighting.

  • Can be used to create zones within open-concept spaces.

  • Placement Guidelines: Position floor lamps in corners to add ambient lighting and fill in dark spots. Place them near seating areas to provide task lighting for reading or conversation. Consider where your dedicated power sources are located.



Under-Cabinet Lighting:

  • Perfect for kitchens as task lighting for food preparation areas.

  • Adds a subtle glow and highlights countertop surfaces.

  • Placement Guidelines: Install under-cabinet lights at the front edge of the cabinet to prevent shadows on the countertop.


Cove Lighting:

  • Installed in ledges or recesses to provide indirect, soft, and ambient lighting.

  • Often used in living rooms, bedrooms, and dining rooms for a cozy glow.

  • Placement Guidelines: Install cove lighting near the ceiling or in ledges to create an indirect, gentle glow on walls and ceilings.


Outdoor Lighting:

  • Includes wall sconces, pendant lights, and post lights for the exterior of the house.

  • Enhances curb appeal and ensures safety at night.

  • Placement Guidelines: Install outdoor wall lanterns around eye level near entrances for safety and aesthetics. Consider glare and light pollution for adjacent neighbors and vehicular traffic at night.


 

Smart Lighting, Dimmers and Controls:


The rising trend of smart lighting systems has revolutionized the way we interact with lighting in our homes. These systems, controlled via apps or voice commands, offer a new level of convenience, customization, and ambiance that traditional lighting setups cannot match.

Smart lighting allows users to adjust the intensity and color of lights with just a few taps on their smartphone or a simple voice command to a virtual assistant like Amazon Alexa or Google Assistant. This level of control enhances convenience in various ways:


  1. Personalized Ambiance: Smart lighting systems enable users to fine-tune the color temperature and brightness of lights to create different moods for various occasions. Whether you're hosting a dinner party, enjoying a movie night, or looking for a cozy reading nook, you can effortlessly adjust the lighting to suit the desired ambiance.

  2. Dynamic Lighting Scenes: With smart lighting, you can pre-set and save customized lighting scenes for different activities. For instance, a "Morning Energize" scene could gradually increase the light intensity to mimic natural sunlight, helping you wake up more gently, while a "Relaxing Evening" scene could dim the lights for winding down.

  3. Remote Control: Whether you're away from home or just in another room, you can remotely control your lights using a smartphone app. This is not only convenient for adjusting lights before you arrive but also for security purposes, giving the illusion of an occupied home even when you're away.

  4. Integration with Home Automation: Smart lighting systems often integrate seamlessly with other smart home devices, such as thermostats, security systems, and entertainment systems. This allows for centralized control, enabling you to create scenarios where lights automatically adjust based on different triggers.

  5. Energy Efficiency: Many smart lighting systems are energy-efficient, allowing you to set schedules for lights to turn on and off, or to dim automatically when natural light is abundant. This not only reduces energy consumption but also helps lower utility bills.

  6. Adaptive Lighting: Some smart lighting systems offer adaptive lighting features that adjust throughout the day to mimic natural daylight patterns. This can have positive effects on your circadian rhythm, sleep quality, and overall well-being.

  7. Voice Control: Voice-activated smart lighting systems, when integrated with voice assistants like Alexa or Google Assistant, offer a hands-free way to control lights. This is particularly handy when your hands are full or when you're unable to use a smartphone.




In our home, we use Google Home devices. Google Home interfaces with smart lighting through voice commands and the Google Home app, providing a seamless and convenient way to control your lights. Here's how it works:


1. Voice Commands: Google Home devices, powered by the Google Assistant, allow you to control your smart lighting using voice commands. Here's how you can interact with your smart lights:

  • Activation Phrase: Start by saying "Hey Google" or "Ok Google" to wake up the Google Assistant on your Google Home device.

  • Controlling Lights: Once the Assistant is active, you can give specific commands like:

    • "Turn on/off [light name or room name]."

    • "Dim/brighten [light name]."

    • "Set [light name] to [percentage] brightness."

    • "Change [light name] to [color]."

    • "Turn on [ name]."


The Google Assistant interprets these commands and communicates with your smart lighting system to execute the desired actions. It's a hands-free and intuitive way to adjust your lights without needing to reach for your phone or a physical switch.


2. Google Home App: The Google Home app is a central hub for managing and controlling your smart home devices, including lighting. Here's how you can use the app to interact with your smart lights:

  • Device Control: Open the Google Home app on your smartphone or tablet.

  • Navigation: Navigate to the "Devices" tab to see a list of all your connected devices, including lights.

  • Individual or Group Control: You can control lights individually or group them based on rooms or zones.

  • Brightness and Color Control: Adjust the brightness and color settings of your lights using the app's sliders and color pickers.

  • Scene Creation: Create custom scenes or routines that involve multiple smart devices, including lights. For example, you can set a "Good Morning" routine that turns on the lights, adjusts the thermostat, and reads you the weather forecast. Our favorite is our "Set the Mood" scene which, against popular thought, is for movie nights :)


In essence, smart lighting systems add an exciting layer of interactivity to interior design. They allow you to curate your home's ambiance at the touch of a button or with a simple voice command, all while maximizing energy efficiency and convenience. This growing trend reflects a desire for adaptable, customizable, and intelligent living spaces that cater to modern lifestyles.




 

Remember, when selecting light fixtures, consider the room's purpose, the desired mood, the existing design style, and the amount of natural light. Layering different types of lighting—ambient, task, and accent—will create a well-balanced and visually pleasing environment. It's also important to pay attention to the color temperature of the light (measured in Kelvin) to achieve the desired warmth or coolness.
