Room-by-Room Interior Lighting Guide | Enhancing Your Home's Ambiance with Lighting

Posted on June 1, 2017

Lighting is a crucial aspect of our homes and businesses, impacting both the aesthetics and functionality of a space. However, it goes beyond that - it can profoundly affect our mood, emotions, and overall well-being. As we approach the darker days of fall and winter, it becomes even more important to understand the significance of indoor lighting.

How can you transform the lighting in your home to create a happier and more productive environment? Thankfully, scientific research on the effects of light can guide your interior lighting design. Rather than undergoing a complete remodel, a few adjustments to your lighting scheme may be all that is needed.

Psychological and Physiological Effects of Light

• Bright light intensifies emotions, both positive and negative.
• Excessive light at night, including electronic media, can disrupt sleep and worsen sleeping disorders. Installing lux on your electronic devices can help combat the negative effects of blue light.
• Natural light (daylighting) improves the health, happiness, and productivity of students and workers. It also reduces utility costs and enhances the well-being of building occupants.

In a study that altered the color and intensity of lighting in a schoolroom, children were observed to be less fidgety and more well-behaved. The electromagnetic energy that emits from light affects the brain's neurotransmitters, which carry messages between nerves and muscles.

Studies conducted on animals, such as rats, have shown that light influences melatonin, a hormone that regulates serotonin levels in the body. Serotonin plays a crucial role in mood, behavior, appetite, sleep, memory, and desire.

Whether you desire a good night's sleep or aspire to improve your relationships and productivity at home, making changes to your interior lighting may hold the solution.

Lighting is both an art and a science. To implement an effective lighting strategy for your home, it is crucial to consult with professionals who possess expertise in electrical systems and lighting design. Apart from technical knowledge, these professionals consider mood, aesthetics, safety, and enjoyment when installing lighting fixtures.

Lighting Design Factors:

• Size and space
• Occupant's age and preference
• Ceiling height and shape
• Color of walls and furniture
• Existing lights and electrical setups
• Points of interest, artwork, and highlight areas
• Traffic patterns
• Shadows and reflections
• Daylight integration
• Surface characteristics
• Color appearance
• Lighting controls and distribution
• Source, task, and eye geometry
• Economics and energy efficiency
• Spatial perceptions
• Level of illumination (lux)
• Psychological and physiological factors
• Electrical codes, documentation, and specifications

While we can provide general guidelines for lighting different rooms in your home, it is important to remember that every home is unique and requires specialized attention. Use this guide as a starting point and consider seeking professional advice to achieve your desired lighting scheme.

Color also plays a significant role in shaping our psychological and physiological states. The combination of room colors and the color temperature of your lighting can make a considerable difference in how you feel.

Lighting Design Layers

Lighting designers usually consider three main lighting categories:

1. General or Ambient Lighting

General or ambient lighting provides overall illumination to make an interior space visible. It is often referred to as natural light or existing light. In addition to natural light, general/ambient light is typically provided by normal room lights.

2. Task Lighting

Task lighting is directed towards specific areas to provide detailed visibility and ensure safe performance of tasks. It is recommended for close-range activities such as cooking, sewing, drawing, and writing.

3. Accent Lighting

Accent lighting is used to highlight specific features, creating visual interest and changing the mood of a room.

Lighting Fixture Types

To simplify your lighting design process, it can be helpful to categorize lighting fixtures into main groups:

1. Surface Lights

Surface-mounted fixtures are visible and flush against the ceiling or wall. They are commonly used in entryways, hallways, and bedrooms.

2. Pendant Lights

Pendant fixtures hang from the ceiling by a cord, cable, or chain. They are often found in dining rooms and kitchens, particularly in homes with higher ceilings.

3. Recessed Lights

Recessed lighting is concealed, typically in a ceiling cavity, to create a clean and glare-free look. This indirect lighting can be used effectively in any room.

4. Track Lights

Track lighting offers flexibility and versatility, with multiple bulbs on a track, providing various lighting options. The fixtures can be suspended from the ceiling or surface-mounted, offering a wide variety of finishes, colors, and styles.

5. Portable Lights

Portable lights are movable and can be plugged into an electrical outlet or operated with batteries. They are often used on desks and bedside tables, providing flexibility in lighting solutions. Floor lamps can also be added to achieve the desired look and functionality.

6. Landscape Lighting

While this guide focuses on indoor lighting, it's important to note that landscape lighting requires its own set of considerations. Outdoor lighting encompasses various types such as bullet lights, flood lights, motion sensors, deck lighting, security lighting, and more. For outdoor lighting installation, maintenance, and repair, consult a professional.

Light Bulb Types

Choosing the right light bulb for each lighting fixture is essential. Consider the following guidelines:

• Dimmable CFLs and LEDs are energy-efficient replacements for incandescent lights.
• Avoid using CFLs with motion sensor devices.
• Select light fixtures designed for LED and CFL bulbs to maximize energy savings.

Color Temperature

The color temperature of light refers to its color appearance. It can be categorized into three main groups measured in Kelvin (K):

• Warm
• Neutral
• Cool

When choosing light bulbs, consider the color temperature based on your needs:

• Warm Light (2700K - 3000K): Conveys a warm and cozy atmosphere, ideal for bedrooms and living rooms.
• Neutral Light (3500K - 4100K): Provides white light suitable for areas that require energy and focus, such as kitchens and bathrooms.
• Cool Light (5000K - 6500K): Delivers a bright, bluish-white light similar to noon on a sunny day. Cool light is great for activities that require attention to detail, such as reading, working, and hobbies.

Consider the impact of color temperature on the mood and ambiance of a space. Choose the appropriate color temperature for each room based on its purpose and the desired atmosphere.

Room-by-Room Interior Lighting Guide

Lighting requirements vary from room to room, depending on the intended use of the space. Here are some guidelines for different areas of your home:

Entryways

Well-lit entryways create a warm and welcoming atmosphere for family members and guests. Use ceiling fixtures to provide ambient lighting and ensure safe passage. Consider the following tips:

Stairs and Hallways

Well-lit stairs and hallways enhance safety and ease of movement. Install fixtures every 4-6 feet to light up the area effectively, define its shape, and highlight artwork and textures. Utilize various light sources such as wall lights and wash lights, depending on the room's size and spacing of fixtures.

Utility Rooms and Garages

Utility rooms, such as laundry and workspaces, require ample ambient and task lighting. Task lighting can be achieved through a combination of track lighting and pendant fixtures for higher illumination.
