SPOTLIGHT FIXTURES

These fixtures are used to provide a narrow and controlled beam of localized light, to the stage. All spotlight fixtures have one or more lenses and are generally available in beam spreads of approximately 5 to 70 degrees.
Designers use spotlight fixtures for AREA and WASH lighting applications, at distances of 15-150 ft. Designers will often provide a series of 'tight', circular pools of light, to each acting area, approximately, 8' to 20' wide (depending on the application). A single acting area will usually consists of 1 to 6 fixtures positioned as; front, back, side or down lights.
FLOODLIGHT FIXTURES
Floodlight fixtures include; SCOOPS, BOX FLOODS and STRIPLIGHTS. These fixtures provide a WIDE distribution of light over a broad area and are primarily used to light backdrops and scenery at close distances of from 3 to 25 feet. Almost all floodlight fixtures are lensless. The exceptions are flood PAR/R lamps that have either spread lenses or diffusion applied to the bulb. Floodlight fixtures generally have fixed beam spreads of 70-150 degrees.
