Fresnels

Fresnel lights are a specialized type of lighting that is used at concert venues and theatres in order to “wash” a specific area of the stage with light. Fresnel lights have a special lens which is able to produce a wider beam with a softer edge, ideal for top lighting and back lighting. Fresnel lights are mostly used for top and back lighting in theatre and concerts, and are placed at a short-to-medium distance from the actual stage. They can also be used for front lighting in smaller venues, as their soft beam is quite distinctive and cannot be replicated easily with other lights, although they suffer the disadvantage of a lack of control compared to ellipsoidal lights. The biggest difference between Fresnel lights and ordinary lights is that they feature quite a distinctive shaped lens, which rather than being smooth like most lenses, is ‘stepped’, giving it a much greater range of curvature. These ‘steps’ allow for the light beam to be more focused, while the light beam is also broken up as it passes through the lens, spreading the intensity fully across the light beam, hence a softer light is produced. Generally, Fresnel lights have a lens diameter of 3, 6 or 8 inches in theatrical use, while the wattage of the lamp can range from anything between 150 Watts to 200 Watts. For film lighting, Fresnel lights are often far more powerful, ranging in size from a 2 inch lens up to 24 inch lenses, while the wattage of the lamp can be as powerful as 20,000 Watts.
