Calculating power
Calculating power
When working with lighting, understanding electricity and how to calculate power usage is essential.
Power is dangerous. Knowing how much power each lighting fixture uses, as well as how much power is available to you in a circuit, is vital to working safely with lights.
The amount of power that is available is an important constraint on lighting design due to the number of lights and their brightness.
It is vital lighting designers and technicians understand how much power can be used safely.

Lighting terminology
Lamp or lantern - the stage lighting fixture made up of two simple components, a globe and a lens to determine the type of light it is.
Light accessories - additional equipment added to a lamp to create a specific lighting effect.
Lighting design - the creation of the atmosphere through lighting for a production, considering visibility, safety and the budget.
General wash - used for general purposes, it is desirable to provide what are called ‘washes’ of light. Washes are general, unfocused light designed to evenly light a certain area of the stage.
Specials or specific lighting – many times it is desirable to accentuate certain portions of the stage with light. This can have a very dramatic effect, but also can be used subtly.
Cyclorama lighting - a cyclorama is a large curtain or wall, often concave, positioned at the back of the stage behind the rear black curtains. They are useful as a screen for a colour wash or projection of gobos - they make an effective canvas for the lighting designer.
Scrim lighting - a scrim is a very specific seamless material - sharkstooth scrim. They can be used almost anywhere on the stage, rather than being relegated to the rear like a cyclorama. Scrims can be used to create silhouettes as they can be lit as translucent or opaque.
Pattern projection - projecting a light pattern on the cyclorama, stage floor or set through various lighting techniques, including the use of gobos. A gobo is a thin, circular plate with holes cut in it to create patterns of projected light.

A stage lamp is made up of many parts.
Many of these elements are common to incandescent, LED and moving style lights.

If you are working with any type of LED lights you will need to have an understanding of DMX and addressing lights. The following 3 videos give a beginners insight into this process.

Addressing LED lights
LED lights need to be addressed when connecting them through a DMX cable to the lighting desk so it can respond accordingly.
The 2 videos 'DMX lighting tutorial: Hardware and software' and 'How to program DMX lights for beginners' provide further information about DMX addressing and how to use the lighting consoles.

Installing lights
Lights can be installed on permanent or portable lighting truss, as well as on the floor. When installing any lights for a production, there are common procedures to follow:
checking lights and power
rigging
patching
focusing
plotting.
The video 'How to rig a light' demonstrates the steps in rigging a light.
How to rig a light
Duration: 05:15Patching lights is the process of plugging in the lights and assigning how they will be operated – this can be done as hard or soft patching.
Hard patching is the physical plugging in of tungsten lights to a patch panel system and then connecting to the dimmer rack.
Soft patching is the process of addressing LED lights and then connecting to the lighting console through the DMX cable or splitter.
Focusing a light is the process of moving the light beam to the exact position on the stage required. This could be in combination with other soft-edged lights to create an even general wash on the specific position for a hard-edged spotlight or gobo pattern.
The video 'Goodstock Greenwich Theatre Get In' is a focus session as a time-lapse.
