S
STROBE
Device giving a fast series of very short intense light flashes which can
have the effect of making action appear intermittent. Because strobe
lighting can trigger an epileptic attack in sufferers, the use of a strobe
must be communicated to the audience before the performance begins. Strobes
should be synchronised so that they operate outside the dangerous frequency
band 4 to 50 flashes per second. (i.e. a strobe should operate at less than
4 flashes per second, or more than 50 flashes per second). If the effect is
momentary, this rule may be relaxed. Strobes must never be used in public
areas where there are changes of level or steps.
Always seek the advice of the licensing authority if you are in any doubt
about the safety of strobe effects.
SUBMASTER
Fader on a lighting desk which can have a lighting state recorded onto it
for additional control, or to use when manually mixing lighting states for
music concerts or one-off events.Lighting desks normally have a series of
submasters (12 or 24 are common) which can have states, cues or effects
loaded onto them. Some desks can have submasters set to inhibit the main
output (known as INHIBITIVE SUBMASTER. For example, the FOH lighting can be
loaded onto a submaster which is then brought down as the house tabs are
flown in between curtain calls to block light spill onto the tabs). Multiple
cues can be recorded onto some submasters through the use of pages. A
PILE-ON submaster can be used to add it's contents to the existing lighting
state. Any number of pile-on submasters can be used in combination to modify
a state.
SUPER TROUPER
Manufactured by Strong International - a range of high intensity followspots
designed for large scale permanent installations or large touring shows. The
Super Troupers use Xenon lamps and vary from 1600 - 2000W. The Super Trouper
is the best known of all stage lighting instruments outside of the industry
due to Abba's song "Super Trouper".
SVOBODA
Low voltage lighting batten used to create a light curtain. Named after
Josef Svoboda, the Czech scenographer (1920 - 2002). The original Svoboda
light batten is still manufactured by ADB. Josef Svoboda contacted ADB when
he was looking for a manufacturer for his idea.
SWARBIES
3 or 4 , 500 or 1000 watt flood lamps mounted on a wooden skid,used as
cyclorama bottom lighting or in between scenery groundrows. Probably derived
from German theater lighting company, Schwabe.
SWATCH

design, or a sample of lighting gel. A catalogue of all the gel colors made
be a particular manufacturer is called a SWATCH BOOK.
SWL

the dominant wavelength. Primary colors are very saturate, while pale tones
are said to be desaturated.
SAVE
Lighting design shorthand for "take a channel to a level of zero." Not to be
confused with the term [Record] used to store a cue in a computer console's
memory.
