Term Definition
Half-Wave Reticifer

A rectifier using only one-half of each cycle to change AC to pulsating DC. Thus, it can cause a flickering effect.

Heat Sink

A piece of metal attached to an electronic component (such as triac, transistor, or voltage regulator) that serves to dissipate or absorb unwanted heat. Many electronics components have two ratings, a lower one when a heat sink is not used and a higher one where a heat sink is in place. Also called a dissipator.

IP Rating

The IP Code/Rating (or Ingress Protection Rating[1], sometimes also interpreted as International Protection Rating) consists of the letters IP followed by two digits or one digit and one letter and an optional letter.

The name is a play on the word kilowatt.

las File

A .las file pertains to a type of Light-O-Rama sequence. .las files are not associated with music therefore, they contain animation only.


Light Emitting Diode. A solid-state, semiconductor device that converts electrical energy directly into light. LEDs show up in Christmas lighting in two contexts: the first is as a power or signal indicator in controllers or SSRs, while the second is their use as a substitute for incandescent lamps. LED Christmas light strings use about one-tenth the energy of an incandescent lamp and have a crystal-clear color brightness that incandescents cannot achieve.

Light Keeper Pro

(LKP) The LightKeeper Pro solves the problem of miniature light set failure because the little red gun actually repairs the set quickly and easily, allowing you to replace the bad bulb causing the disruption in the electrical current.

lms File

A .lms file pertains to a type of Light-O-Rama sequence. These file extensions are connected with musical sequences and contains the music location along with commands.


Is short for the company Light-O-Rama that makes software and hardware for all lighting occasions.
