How do I measure the quality and type of indoor lighting?

Indoor lighting is a key factor that affects our mood, productivity, health, and well-being. But how can we measure the quality and type of indoor lighting in our home offices? Here are tips and tools that can help you assess your home office environment.

First, you need to understand the distinct types of indoor lighting and their characteristics. There are three main types of indoor lighting: natural, artificial, and mixed. Natural lighting refers to the sunlight that enters through windows or skylights. Artificial lighting refers to the electric lights that we use to illuminate our spaces. Mixed lighting refers to the combination of natural and artificial lighting sources.

 

Quality of Indoor Home Office Lighting

The quality of indoor lighting depends on several factors, such as:

 

Amount of Light:

Light is measured in lumens, which indicate how much light is being emitted by a source. The recommended amount of light for different activities varies, but you need more light for tasks that require high visual acuity, such as reading or working on a computer, than for relaxing or sleeping.

Color Temperature:

Color Temperature is measured in kelvins, which indicates how warm or cool the light is. The color temperature affects the appearance of colors and the mood of the space. For example, warm light (below 3000K) tends to create a cozy and relaxing atmosphere, while cool light (above 5000K) tends to create a bright and energetic atmosphere.

Color Rendering Index

The CRI is a scale from 0 to 100 that indicates how accurately a light source renders colors. The higher the CRI, the more natural and vivid the colors appear. A CRI of 80 or above is considered good for most indoor applications.

Glare

This is the excessive brightness that causes discomfort or reduces visibility. Glare can be caused by direct or reflected light from sources that are too bright or poorly positioned. Glare can cause eye strain, headaches, and fatigue.

 

Measuring

To measure the quality and type of indoor lighting, you can use simple tools and methods, such as:

 

A light meter: This is a device that measures the amount of light in each area. You can use a light meter to check if your indoor lighting meets the recommended levels for different activities and spaces. You can also compare the readings from various sources and locations to find the optimal balance of natural and artificial lighting.

A color meter: This is a device that measures the color temperature and CRI of a light source. You can use a color meter to check if your indoor lighting matches your preferences and needs for various times of the day and seasons. You can also compare the readings from various sources and locations to find the optimal mix of warm and cool lighting.

A smartphone app: There are apps that can measure the amount, color temperature and CRI of indoor lighting using your smartphone’s camera. These apps may not be as accurate as dedicated devices, but they can give you an idea of your indoor lighting quality and type. Examples of these apps are Lux Meter, Light Meter, and Color Temp Meter.

A visual inspection: You can also use your own eyes to assess your indoor lighting quality and type. You can look for signs of glare, such as squinting, shadows or reflections on screens or surfaces. You can also look for signs of insufficient or excessive lighting, such as dark spots, eye strain or headaches. You can also check how colors appear under various sources and locations of lighting.

 

By measuring the quality and type of indoor lighting, you can improve your indoor environment and enhance your comfort, health, and well-being. You can also save energy and money by choosing the most efficient and appropriate lighting solutions for your needs.
