Concert lighting

The art and science of concert lighting.

Lighting can be a very dramatic tool for a live event.  In this series of videos we learn about the purpose and creativity behind lighting and the technology that creates this visual element.


Lighting can demonstrate additive and subtractive color mixing, color filtering, reflection, refraction and absorption.   In addition, we will learn about optics, electricity and many other scientific subjects. 

Introduction to lighting and related calculations

Basic math and science of lighting.

Basic math and science of lighting.

Basic math and science of lighting.

In order to design lighting for a concert production, we need to understand some of the basic math and science behind it.


In addition to general math skills, we need to understand color, optics, electricity, weights, forces and other subjects.


These videos will demonstrate how real world applications of basic math and science help us to design and pre-engineer a concert lighting system.

Types of lighting fixtures.

Basic math and science of lighting.

Basic math and science of lighting.

The two basic type of lighting fixtures are soft edge and hard edge lighting.


In order to produce the desired effect, we have to understand the basic principles of optics.


An example of hard edge fixture would be a spotlight.


A soft edge fixture would be a flashlight, it still produces a beam, but the edges are not defined.





Calculating distance.

Basic math and science of lighting.

Determining Lighting Fixture Based Upon Distance.

In order to determine the proper lighting equipment, we must first calculate how far our light is from the object that is to be lit.

Once we have calculated the distance from our light to our object, we can determine which fixture to utilize.


This video gives a brief introduction to lights, the types of beams and their distance capabilities.

Beam Sizes
