Stage Lighting Dimming

A dimmer is a device used to vary the electrical power delivered to the instrument’s lamp. As power to the lamp decreases, the light fades or dims. It is important to note that some color change also occurs as a lamp is dimmed, allowing for a limited amount of color control through the dimmer. Fades can be either UP or DOWN, that is increasing or decreasing the intensity. Today, most dimmers are solid state, although many mechanical dimmers still exist.

Focus, position, and hanging of Stage Lighting

Focus is a term usually used to describe where an instrument is pointed. The final focus should place the “hot spot” of the beam at the actor’s head level when standing at the center of the instrument’s assigned “focus area” on the stage. Position refers to the location of an instrument in the theater’s fly system or on permanent pipes in front-of-house locations. Hanging is the act of placing the instrument in its assigned position.

Pattern of Stage Lighting

Pattern refers to the shape, quality and evenness of a lamp’s output. The pattern of light an instrument makes is largely determined by three factors. The first are the specifics of the lamp, reflector and lens assembly. Different mounting positions for the lamp (axial, base up, base down), different sizes and shapes of reflector and the nature of the lens (or lenses) being used can all affect the pattern of light.
