Generic lighting
Generic lighting is used to provide spotlights for lecterns or overall lighting for a particular stage area and fall into three basic lighting types; Profile 'special' these can be used to focus light tightly onto a lectern, a set mounted logo, seating area or any other area that needs a defined area of light. Fresnel ‘wash light' are usually used to illuminate larger areas of a stage or set. These lamps cannot be focussed as tightly as a profile lamp but the beam can still be narrowed or expanded. Par cans lamps cannot be focused or adjusted in any way as they are solely designed to provide a bright, punchy beam of coloured light.
LED lighting
LED lighting is built from relatively new technology, and is used increasingly in the conference market for set illumination. The advantages are numerous, firstly that a range of colours can be achieved from each lamp, rather than using a single piece of coloured gel covering the lens. Secondly, the power requirements are far less than for a generic lamp and operate at a much lower temperature than standard lamps.
Moving/intelligent lighting
Generally known as ‘Macs’ these types of lights are programmed to move from side to side and up and down and project effects onto sets or around a venue such as stars, circles or other shapes. They are also used to hold ‘gobos’ and can also project a range of colours.
Gobos
A gobo is best compared to either a stencil or photographic slide. Gobos are used in most types of stage lamps or moving lights, and can be used to project logos, patterns or photographic images.
