Term Definition

A sequence is an ordered list of objects or events. Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. A sequence is a discrete function.

Sequence Backup Utility

Sequence back up management. Automatically make backups of each saved file. Allows you to get the old version back.


ServoDog 8

The ServoDog is more than just an 8 channel servo board. The 8 channels can run either in servo mode or as standard logic level outputs to power low current items such as LEDs or Solid State Relays. In addition two of the channels can be configured as high current PWM channels with their own power input to run DC motors, LED spot lights etc...

Shrink Wrap

Shrink wrap, also shrinkwrap or shrink film, is a material made up of polymer plastic film. When heat is applied it shrinks tightly over whatever it is covering. Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel on a conveyor.


A snubber is a device used to suppress ("snub") voltage transients in electrical systems. They are mostly used on LED's.

Spiral Tree

A mega-tree, Scott Weber created, that has lights running from top to bottom in a spiral fashion unlike a typical mega-tree, up and down.


Service Parallel Thermoplastic. Commonly referred to as zip or lamp cord. There is SPT1, SPT2, and SPT3. The number refers to the thickness of the insulation in 64ths of an inch. SPT1 is often called lamp cord. SPT1 usually has 18 gauge wire. SPT2 is commonly available in 16 or 18 gauge. SPT3 is available as large as 10 gauge.


Solid State Relay. An electronic switch, which, unlike an electromechanical relay, contains no moving parts.

Strobe Light

Strobe lights come with a C7 or C9 socket built on the end in either LED or xenon bulbs.. This makes installation much easier and faster, no more messy cords. The majority of decorators use strobe lights that have 3 to 4 flashes per second. These lights add a sparkle to the display. But, when sequencing, they can only be turned off or on at 100%.

Super Star Sequence Editor

The SuperStar Sequence Editor was created to allow easier creation of light shows. The principle is to never manipulate the channels directly. Light-O-Rama recently went into agreement to add this module to it's new S3 software.



Standing Wave Ratio. The ratio of the maximum (voltage, current) to the minimum (voltage, current) points of a transmission line. Indicates the impedance matching quality of the termination of the line.
