What Is Light?

Light is an electromagnetic radiation source that stimulates sight to make things visible as it illuminates using a natural matter like the sun or an artificial object like a flashlight or lamp. It is made when an electron moves from a higher to a lower energy level. It is a fundamental tool for appreciating, communicating, and perceiving the visual world around us. 

Based on a recent Residential Energy Consumption Survey (RECS) report, almost 47% of households in the United States are using LEDs for the majority of their indoor lighting in 2020. U.S. households using mostly fluorescent bulbs for their indoor lighting fell from 32% in 2015 to 12% in 2020 and other homes using incandescent bulbs dropped from 31% of the total in 2015 to 15% in 2020. This report and other science research reports show that many people are increasingly switching to using LEDs and smart lighting systems such as smart lamps that are programmed via apps. 

Types of Lighting

The lighting used in one space usually differs from another room. Interior designers and decorators highly consider the right lighting they will implement in a room as they tailor each room based on its purpose. On the other hand, photographers utilize natural light in their shoots in various ways. Take note of the different types of lighting used by interior designers and photographers. 

Ambient Lighting: Also referred to as general lighting, ambient lighting is a bright and dynamic illumination that gives you equal illumination levels over the whole space completely independently from other lighting sources. LED downlights, track lights, and wall-mounted fixtures are some fixtures most often used to create ambient lighting indoors, while bollard and path lights, lanterns, and sconce and wall-mounted lighting fixtures are used outdoors. Accent Lighting: This type of lighting is used when you aim at specific points of interest to reach a certain desired lighting effect. Highlight a particular lighting feature or decoration if you prefer to create a unique impression of a larger, sophisticated room. Accent lighting is used when you like to emphasize a certain collection or object in your room as it shines three times as much light on the focal point. To provide accent lighting, it is recommended that you use a directional recessed fixture or downlight, tape and extrusion, or wall-mounted fixtures. Decorative Lighting: Make a solid statement in your area when creating your decorative lighting selection. From the name itself, determine the direct, upward, or downward lighting, color, and size so that you rchieve the effect you have in your mind. Then, set the position of your decorative lights, their color, and their style carefully. Pendant lighting, table and floor lamps, and wall sconces are some common types of decorative lighting.Task Lighting: Use lamps when you are performing some daily tasks at home. Choose task lighting devices that meet your specific functional needs. Some examples of task lighting devices are bedside lights, under-cabinet lights, and desk lights. Reflected Lighting: If you want to take soft pictures, use reflected lighting from items that can reflect light such as glass, rock, mirror, water, and other objects that allows light to be reflected from one surface to one another.

Benefits of Light

Light is oeen in our environment as we are filled with bright yellow warmth from the sun during the day and the cool mysterious silver light from the moon during the night. We also enjoy catching glimpses of light when we see a rainbow after a storm and observe the glistening light filtering through the tree leaves in the forest. What are the notable benefits of light?

1. Boosts Work Productivity

A Future Workplace survey report revealed that over 1,600 employees ranked “access to natural light and views of the outdoors” as their number one desire for a workplace environment. This appears to be their top priority above other perks such as fitness centers and on-site childcare. Another case study reported that workers sitting near a window that optimized daylight exposure had a 2%-15% increased productivity rate which means an additional $100,000/year of value for every 100 workers. Having good natural lighting has been linked to higher energy and increased productivity.

2. Prevents Seasonal Depression and Improves Mental Health

Studies have shown that about 6% of the population experiences a time of serious depression called a seasonal affective disorder or major depressive disorder with seasonal patterns. On the other hand, another 14% had winter blues. Going outside to get some sunshine and Vitamin D is a great way to ward off this disease. Vitamin D is a fantastic vitamin that can help ease your mind from daily stress factors. Plus, doing this will help you improve your mental health and sleep.

3. Reduces Eye Strain 

Smartphone screens and computer screens that emit blue light can cause eye strain and can have negative effects on our vision. Researchers discovered that fluorescent lighting can also be possibly damaging to our eyesight. Avoid spending time under artificial lights and opt for more bright outdoor light in your home. 

4. Saves Energy and Money and Helps Protect the Environment

Placing windows strategically to allow the abundance of natural light passes into your home is a great method to decrease the amount of electricity necessary to provide light for your home. For example, use large windows in your living room or horizontal windows close to the top of your bedroom walls. Also, using natural lighting to illuminate your home can be beneficial to protect the environment. Electricity production requires the burning of fossil fuels. So, if you reduce artificial lighting in your home through natural lighting and monitor your energy consumption from lighting devices using an equipment maintenance checklist, it will lower your energy consumption and increase environmental sustainability. 

5. Enhance the Aesthetic of a Space

Natural lighting can help you enhance the overall aesthetic of your space. It can highlight the calming natural aesthetic of spaces in your home. For instance, more natural lighting can turn spaces appear larger and enlighten focal points such as artwork, chandeliers, plants, sculptures, or architectural elements.

How to Use Light Efficiently

From the sunlight that lits in your window to metallic mirrors, there are a variety of items and objects that help you emit light and use it properly. What are some ways to use light efficiently in your everyday lives?

Step 1: Add Mirror Effect

Allow sunlight to bounce around your space with a mirror or more objects that can reflect light. Adding a mirror effect can cast more brightness between the four walls of your room. Get the most out of the reflection and place the mirrors or metallic objects such as brass candlesticks or silver sconces in the path of the sun’s rays.

Step 2: Maximize Natural Light Colors

Colors close to white such as light pastel colors, neutral beige, and off-white tones are wonderful natural light colors that you can use in your room. Include subtle prints and patterns based on white and light natural color palettes to help you create beautiful and cozy sunlit settings. For example, select Nordic and Scandinavian decor as they mostly feature white and neutral shades. Go for botanical prints to fully strengthen the nature-inspired theme of your area. To add depth and interest, use a light wooden flooring and subtle hints of pastel colors and earthy tones.

Step 3: Select Energy Saving Light Bulbs

Choose LED lights because they reduce lighting costs by around 30-50%. Or you may choose compact fluorescent lamps or CFLs because they use about one-quarter to one-third as much energy to generate the same amount of light as a standard incandescent light bulb. Get some three-way bulbs as they can operate at three different wattages so that you can choose the lowest wattage for your needs.

Step 4: Utilize Artificial Lights Efficiently

Select the right light fittings. Turn lights off when you don’t use them. If you are using smart lighting systems, use intelligent lighting controls from your light bulb saver app to assist you in saving energy. You can use an energy management system as well by integrating dimmer switches and affixing multiple switches.


What are the fundamental characteristics of light?

The fundamental characteristics of light are the reflection, refraction, dispersion, diffraction, polarization, and interference of light. Reflection occurs when each light follows the law of reflection when the angle of incidence is equivalent to the angle of reflection. Refraction happens whenever the velocity of a light ray fluctuates despiting traveling from one medium to another. Dispersion is when the white light strikes through a prism as it divides into a wide array of shades depending on wavelength. Diffraction is the phenomenon of light bending across tiny obstacle angles. Polarization is when ordinary light resonates with the light transmission perpendicularly. 

What are the primary colors of light?

The primary colors of light are red, green, and blue. Combining these colors in varying proportions can produce all the colors of the light we see around us. For example, mixing two of the three primary colors of light create the secondary colors of light: cyan, magenta, and yellow.

What is light made of?

Light is made of photons which are particles that emit energy. These are generated when the atoms in a certain object heat up or the electrons inside the atoms are heated and acquired extra energy. The extra energy turns into a photon when released.

What are the common types of light sources?

The common types of light sources are incandescence and luminescence. These basic light sources produce incandescent light and luminescent light. The most common type of light is incandescent light from the sun, fires, and light bulbs. While luminescent light is made when an electron releases some of its energy as electromagnetic radiation, for example, from fluorescence light, bioluminescence or light from biological animals and plants, electrical currents, neon lights, and many others. 

What are the basic types of lighting features?

The basic types of lighting features used in interior and exterior design for buildings and rooms are ambient lighting, accent lighting, task, lighting, and decorative lighting. 

What are the 8 types of natural light used in photography?

The 8 types of natural light used in photography are backlight, sidelight, front light, reflected light, diffused light, dramatic light, twilight, and night light.  

From our smartphones, TVs, windows, and the sun, light is seen and used vastly anywhere. Whether you are reading a reflective essay on your android device, writing technical proposals on your laptop, designing your interior spaces or you are working to save energy consumption, light is a fundamental aspect of our lives as we need to use it efficiently.
