-Very similar to a [[wiki:glossary:lighting_glossary#gobo_rotator|rotating gobo]], but the center of rotation is outside the beam of the light. Often combined with a [[wiki:glossary:lighting_glossary#gobo_rotator|rotating gobo]] to give watery effects / fire effects.+Very similar to a [[wiki:lighting:lighting_glossary#gobo_rotator|rotating gobo]], but the center of rotation is outside the beam of the light.

 These are used on the front of fixtures to mask off the edges of the beam of light to stop light shining on to things which need to be kept dark (e.g. certain parts of the stage, or the [[wiki:glossary:general_terms#tab|tabs]]). These are used on the front of fixtures to mask off the edges of the beam of light to stop light shining on to things which need to be kept dark (e.g. certain parts of the stage, or the [[wiki:glossary:general_terms#tab|tabs]]).

 Abbreviation for Cyan, Magenta, Yellow. A colour mixing system used in lighting fixtures. Essentially the inverse of RGB (Red, Green, Blue). RGB can be used with floods to create pretty much any colour needed on a [[wiki:glossary:general_terms#cyclorama|cyc.]] for example. Abbreviation for Cyan, Magenta, Yellow.

 ====Colour Wheel==== ====Colour Wheel====
-Moving fixture equivalent of a [[wiki:glossary:lighting_glossary#scroller|scroller]]. It is a small wheel inside a fixture, which rotates in the beam of light allowing you to control the colour of the light. These do not use [[wiki:glossary:lighting_glossary#gel|gels]], since they would wear too easily.+Moving fixture equivalent of a [[wiki:lighting:lighting_glossary#scroller|scroller]].

 ====Dimmer==== ====Dimmer====
-A device that distributes power to the lighting fixtures. The amount of power to each fixture is goverened by the value specified for the fixture's [[wiki:glossary:lighting_desks#channel|channel]] on the [[wiki:glossary:lighting_glossary#dmx|DMX]] line.+A device that distributes power to the lighting fixtures.

 ====Distro==== ====Distro====
 Short for Distribution Unit: used to split up power in to combinations of smaller ampage outlets often used to producer single phase neutral power from three phase neutral power as well. Should be fitted with RCB trips. Short for Distribution Unit: used to split up power in to combinations of smaller ampage outlets often used to producer single phase neutral power from three phase neutral power as well.

 ====DMX==== ====DMX====
-Acronym of Digital Multiplex. This is the protocol that the [[wiki:glossary:lighting_glossary#dimmer|dimmers]], intelligent lights, and lighting desks use to communicate. DMX cable, comes in five or three pin versions, but the connections and protocol are the same. DMX cable is not the same as [[wiki:sound:sound_glossary#xlr|XLR]] cable, although [[wiki:sound:sound_glossary#xlr|XLR]] cable can be used for short stretches.+Acronym of Digital Multiplex.

 Used to be made of gelatin, hence the name. They are the sheets of coloured plastic used to colour light. You can get bored and order mini swatchbooks for the fun of it too! Used to be made of gelatin, hence the name. They are the sheets of coloured plastic used to colour light.

 Internally Wired Bars. Basically a long scaff bar, with wires inside, and sockets along the length. If you're lucky, you get them like Arts H, where you have God knows how many phases going through one bar. Internally Wired Bars.

 ====Scroller==== ====Scroller====
-This is a device, in which you take a lot of cuts of [[wiki:glossary:lighting_glossary#gel|gel]], and stick them together into one long scroll. You can then use a controller to scroll the [[wiki:glossary:lighting_glossary#gel|gel]] around to the colour you want. This is handy when using limited fixtures, and being able to control the colour of them.+This is a device, in which you take a lot of cuts of [[wiki:lighting:lighting_glossary#gel|gel]], and stick them together into one long scroll.

 Used in intelligent fixtures, the shutter is the piece of metal which can cover the whole beam. Depending on how good the fixture is, as you bring the shutter in, the light intensity will fade, or you will see the shutter come across the beam of light (having a semi-circle of light when the shutter is halfway in!) Used in intelligent fixtures, the shutter is the piece of metal which can cover the whole beam.

-The shutters are a set of four pieces of metal that can be used to mask off the edges of the beam of light. Typically used in a similar way to [[wiki:glossary:lighting_glossary#barndoors|barndoors]] however, can also be used to produce "square" spots i.e. a door spot.+The shutters are a set of four pieces of metal that can be used to mask off the edges of the beam of light.
