10 Steps to Better Light Quality (2024)

Lighting quality in a specific space is always the result of the blending of the architecture, light source(s), relation to the visual task, and the preferences and needs of the users. This makes it very hard to develop a single formula that will always create magnificent lighting in every space. The debate over creating a ‘recipe‘ for quality lighting will go on for a long time. Here are some simple lighting measures that will almost always improve your lighting quality.

Switch From Cool and Warm White Lamps to Rare Earth (RE)

  • RE lamps give better color quality and often produce more light.
  • Virtually all T8 lamps are RE.

Switch From Magnetic Ballasts to Electronic

  • Electronic ballasts help eliminate flicker and hum (big on the list of user complaints).

Put More Light on Ceilings and Walls

  • Ceiling brightness makes spaces seem taller.
  • Brighter walls make spaces seem bigger.
  • Uniform brightness can reduce user eye strain from ‘glare’ problems.

Add Paint to Your Lighting Tools

  • Lighter color values improve the efficiency of your lighting equipment and make spaces brighter.

Include Daylight in Your Lighting Plan

  • Daylight is usually the first choice for users — it has the best color, gives a connection to seasonal rhythms, and usually comes with a view.

Light Architectural Details and Artwork

  • Give users a sense of depth, shadow and contrast for visual variety.
  • The eye needs variety to stay interested and awake.

Determine Who Will Use The Space

  • Age of users changes the amount of light needed for seeing and the amount of glare that can be tolerated determine what the users will be seeing.
  • Visual tasks are the basis for when, where and how the light should be distributed.

Calculate Lighting Performance of Your Designs

  • Create good estimates of the lighting distribution in the space don’t just fill in the holes in the ceiling grid.
  • Manual lighting calculations are not hard to learn.
  • Lighting software is easily available.

Know When to Hire a Lighting Professional — and do so

  • Good lighting designers offer a range of solutions to lighting problems —knowledge of equipment, creative applications and comprehensive project management.

Following these tips won’t necessarily win you an international award in lighting design. But they might help reduce some of your (and your users) lighting headaches. #

FAQs

How do you describe the quality of light? ›

The two common terms used to describe light quality are hard and soft. Hard light, such as the sun at high noon, will create intense shadows and more contrast. Diffusing the light produces softer shadows and reduces contrast, as seen in the image on the right.

What determines light quality? ›

Three characteristics make up light quality: Illumination Intensity (Lux / lx) – the total amount of light that falls on a surface from a light source. The source of the light is measured by luminous flux, in lumens. Colour Temperature (Kelvin / K) – the warmth of the light, from yellow to blue.

What is the basic theory of light? ›

Basic Theory

Light is a form of radiant energy that travels in waves made up of vibrating electric and magnetic fields. These waves have both a frequency and a length, the values of which distinguish light from other forms of energy on the electromagnetic spectrum.

What are the four elements of lighting? ›

Understanding the functions and the role that light plays is not enough to be able to craft cinematic images; you also need to understand the four elements: color, angle, intensity, and quality.

What are the 10 characteristics of light? ›

What are the general characteristics of light?
  • Light is a form of energy produced by luminous objects.
  • Light travels in a straight line.
  • Light can travel through a vacuum.
  • Light can be reflected.
  • Light can be bent/refracted.
  • Light travels with a speed of 3.0 × 108 m/s in a vacuum.

What are the three most important qualities of light? ›

  • An introduction to lighting for photojournalists. Note: Many of these photos were taken by photojournalism students in COMM 242.
  • The three characteristics of light:
  • Intensity. Light can vary in intensity by as much as 1,000 times. ...
  • Quality. Light is perceived as hard or soft. ...
  • Direction. ...
  • Color balance.

What are the three principles of light? ›

In photography, there are three main principles: instensity/quantity of light, direction of light, and quality of light.

What are the 5 theories of light? ›

The different theories of light include Maxwell's Electromagnetism and Quantum Electrodynamics . The ether-wave theory, tactile theory, Newtonian corpuscular theory, Ritz extinction theory, and the Special Theory of Relativity are not supported by evidence .

What is the first law of light? ›

The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane. The second law of reflection states that the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror.

What are the elements of light elements? ›

The observed amounts of the lightest chemical elements, such as hydrogen, deuterium, helium, and lithium, imply that these elements were created early in the history of the Universe before stars formed.

What are the 7 components of light? ›

White light is composed of seven components. These colours are violet, indigo, blue, green, yellow, orange and red.

What are the 5 main criteria of lighting? ›

These basic qualities of light are; INTENSITY, FORM, COLOR, DIRECTION and MOVEMENT.

What is the word for the quality of light? ›

Incandescent: glowing, gleaming, warm, emitting light; a source of light; brilliant. Iridescent: rainbow colored, blazing; lustrous; shining; of a bulb; radiant; Lucent: bright, clear, shining; radiant; intense; dazzling; luminous; brilliant; ablaze; glowing with or giving off light.

How can we determine the quality of light? ›

Measuring Lighting Quality. Measuring the brightness and energy use of light sources is straightforward. Divide the lumens by watts and you have the amount of light produced per unit of energy expended, or lm/W.

What is the best description of light? ›

Light is defined as the electromagnetic radiation with wavelengths between 380 and 750 nm which is visible to the human eye.

What is the quality of light called? ›

Color rendering describes the quality of light and is denoted as Ra (Europe) or CRI (US). The chart below shows a comparison between different light sources. Zumtobel uses exclusively LED modules and the majority of our products achieve CRI 80+ or CRI 90+.
