Spectral Distribution Chart

Understanding Spectral Distribution Chart WHAT IS A SPECTRAL DISTRIBUTION CHART? The spectral distribution chart is a visual representation of the light spectrum produced by a lamp. It is a graph showing the relative intensities of a light source at each wavelength.These charts can be used to compare the energy levels of various light sources. They…

Light Spectrum

Understanding Light Spectrum Light spectrum is the many different wavelengths of energy produced by a light source. Light is measured in nanometers (nm). Each nanometer represents a wavelength of light or band of light energy. Visible light is the part of the spectrum from 380nm to 780nm.

Correlated Color Temperature (CCT)

Understanding Correlated Color Temperature (CCT) There are a number of color combinations that can be used to create White Light, or a particular Color Temperature. The Chromaticity Chart is used to qualify the color of the light that is produced by a lamp. This is called a lamp’s Color Temperature. This can be seen on…

Color Rendering

Understanding Color Rendering The eye sees all objects in the form of reflected light. All of the colors contained in the object must also be present the beam of light to accurately reproduce the image in reflected light. The Color Rendering Index is a numerical scale from zero to one hundred used to rate the…

General Lighting Terms

Here are some general lighting terms that most in the commercial, institutional and utility industry need to know. Accent Lighting: Directional light that is used to emphasize or highlight a particular object. Ampere: The standard unit of measurement for electric current that is equal to one coulomb*, per second. It defines the quantity of electrons…
