Edison Connector: The standard household male, parallel-blade plug that may or may not have a ground pin.

Edison Lamp Holder: The standard household screw-in lamp socket that accepts medium screw type lamp bases.

Egg Crate: A square or rectangular grid that, when installed on large open face light sources, alters the shape and intensity of the light and reduces glare.

Electrical Current: The flow of electrons from one point to another, measured in Amperes.

Electrical Frequency: The cycles per second of alternating current, measured in Hertz. In North America, and parts of South America and Southeast Asia, the frequency is 60Hz. The rest of the world operates on a frequency of 50Hz.

Electrical Noise: A general term for an unwanted electronic disturbance in conductors or electrical or electronic equipment. This equipment can also be the cause of electrical noise.

Electrical Power: The rate at which electricity is delivered to a circuit, in watts, or in reference to magnetic transformers, in Volt-Amperes.

Electronic Ballast: A ballast uses electronic components to limit electrical current. This type of ballast is often referred to as a flicker-free ballast.

Ellipsoidal: Short for Ellipsoidal Spotlight.

Ellipsoidal Spotlight: A spotlight that is encased in an ellipse-shaped reflector and framing shutters, and sometimes an iris and pattern slot.

Eye Light: A small, intense light source used to front light a subject, usually a person`s face, with hard light.

Fahrenheit: A graduated scale used to measure temperature. In the Fahrenheit scale, the freezing point is 32°F and the boiling point is 212°F.

Falloff: A term used to describe the illuminated area just outside of the field. (This term may also refer to the illumination in this area.) Light from a point source falls off inversely to the square of the distance. Move the light from 10` away to 20` away, and you have 1/4 of the intensity 40`, 1/16th.
Diffused lights fall off even faster than point sources. See Inverse Square Law.

fc: Abbreviation for foot-candle.

Feed Through: A wiring system employed in some electrical equipment and light sources in which the line-side leads or flush-mount connector(s) for a first item branch into two circuits internally. One circuit provides the electrical supply to the item itself, and the second circuit exits the unit by means of a set of load-side leads or another flush-mount connector(s). This allows for a second item to be electrically connected to the first. A plurality of items may be connected in this way, usually light sources such as strip lights. See Daisy Chain.

Female: A term applied to a connector that contains the holes or slots for receiving the pins, prongs, blades or tabs of a male connector. The female connector should always be attached to the line side of a circuit.

Field Angle: The angle of the vertex of a cone-shaped beam where the perimeter of the base is defined by where the intensity is 10% of the maximum intensity.

Field Diameter: The diameter of the base of a cone-shaped beam where the perimeter of the base is defined by where the intensity is 10% of the maximum intensity.

Filament: The wire inside an incandescent lamp envelope that glows and emits light when heated, i.e., when electricity passes through it.

Fill: To create the illumination needed to reduce shadows in an area or on a subject.

Fill Light: Angled from the side opposite the key light, this light softens the shadows created by the key and evens out the lighting ratio.

Filter: A term that refers to color media, diffusion material, light blocking or neutral density.

Filter Frame: See Color Frame.

Finger: A small, narrow, rectangular scrim, diffuser, reflector, or gobo, placed close to a light source, used for dimming, softening, bounce lighting, and casting shadows, respectively. Fingers are usually 2" to 6" in length, and 12" to 14" in width.

FL: A lamp designation that means flood.

Flag: (Filter, Gobo) An opaque panel, usually made of fabric, placed in the beam of a light source to block a portion of the beam or the whole beam. It can also hide lights in the dark recesses of a scene. They are usually square or slightly rectangular in shape, ranging from 10" to 48" in length, and 12" to 48" in width. Which term you use depends upon the device`s size and what part of the country you are in.

Flash: A tube filled with xenon gas through which an electrical charge of high voltage is passed to create an electrical arc that emits a short, bright flash of light. Flash light is daylight balanced, usually measuring 5500° Kelvin. See Strobe.

Flat Light: See Diffuse Light. All light is characterless, texture less and shallow shadowed when the source is close to the camera. Soft light is, by its nature, flatter than hard light, but even a soft source, above or to the subject`s side, is not flat.

Flicker: The flashing of some light sources that cannot be visually detected because of the frequency of its output voltage, but can adversely affect the way motion picture film records light.

Flicker-Free: A term used to describe electronic ballasts that electronically alter the electrical frequency that causes flicker.

Flood: The position of a moveable lamp, lens or pair of lenses on a spotlight that produces the widest field angle. To direct a large amount of light on a relatively large area.

Flood Light:A light source consisting of a rectangular lamp and sometimes a single lens, used to direct a large amount of light on a relatively large area.

Floppy Flag: A large flag that is designed to fold in half and function as a cutter or smaller flag.

Fluorescence: The property of certain materials to absorb radiation of certain wavelengths, usually ultraviolet, and re-emit the radiation as light.

Fluorescent Lights: Cool and daylight balanced, fluorescent lights have become very popular for photographic and video capture. Fluorescent lighting can be used in the form of screw-in bulbs and reflectors, or rectangular banks of lights.

Foamcore: A polystyrene, Styrofoam material used as a substrate for some reflector boards, effective because of its light weight and ease of mounting via reflector forks.

Focus: To aim and adjust a light source to give the beam its desired size (spot or flood), edge (soft or hard), field (even or peak) and shape (round, patterned or cut).

Focus Lens: A movable lens in a multi-lens optical system that adjusts the focus of a light source.

Follow Spot: A narrow-beam focusing instrument that is manually operated and is usually composed of a powerful light source, an iris, shutters, a color changer and other features. It is usually operated from an adjustable stand and is used to follow performer(s) on a stage with its beam, surrounding the performer(s) in a large pool of light.

Foot-candle (fc): A non-metric unit of measurement for Illumination, i.e., 1 lumen per square foot.

Framing Projector: A spotlight that has framing shutters or barn doors.

Framing Shutters: Thin, movable, heat-resistant metal plates that are introduced into a beam such that a portion(s) of the beam is blocked off,i.e., framed affecting the beam pattern, usually forming a sharp edge in the beam. They are used in various types of light sources, but extensively in ellipsoidal spotlights, usually four (top, bottom, right and left) follow spots, usually two (top and bottom), always situated internally, and usually at the aperture. Framing shutters generally can be independently adjusted, but those used in follow spots usually move simultaneously with a single control mechanism.

French Flag: A small metal flag, usually used for shading.

Fresnel: Short for Fresnel Spotlight.

Fresnel Lens: Named for its inventor, French physicist Augustin J. Fresnel, and developed around 1800 for lighthouses, this is a flat lens consisting of concentric rings on one side that are segments of the spherical portion of a Plano-convex lens. The other side is flat, i.e., Plano. It controls light in the same manner as a Plano-convex lens, which converges light into a beam.Many light sources employing this type of lens have a stippled pattern on the flat side of the lens to diffuse to smooth out the beam.

Fresnel Spotlight: A spotlight employing a single Fresnel lens that produces a soft-edged beam, usually provided with a spherical reflector and a means to adjust the focus from spot to flood.

F/Stop: A rating often applied to scrims used in the film and video industries on their ability to dim light. This rating is directly related to a camera`s ability to allow for the admittance of light.

Full Scrim: A metal scrim whose screen occupies the complete frame.

Fuse: An electrical device designed to stop the flow of electricity automatically when a predetermined over current tries to pass through it. This is meant to prevent further damage or fire from overheating.

Fused Quartz: A relatively pure, high-temperature glass used to manufacture lamp envelopes. It has a melting point of approximately 1650° C.

Gaffer: The lighting technician who is in charge of the electrical aspects of a set or production.

Gaffer Grip: A large, spring-loaded clamp with serrated or rubbercushioned jaws. It usually has a stud or studs for the attachment of luminaries and grip equipment.

Gaffer`s Pole: See Operating Pole.

Gag: An apparatus composed of two grip heads attached to each other via a common bolt.

Gel (Gelatin, Media): As used with photographic lights, a strong, flexible, fade-resistant material, used to change the color, amount or quality of light. A colored filter placed in front of a lighting fixture. Color is an important element in adult learning.

Gobo: A logo or image etched out of metal that allows it to be projected onto a screen, wall, banner or other solid surface. Often used for brand reinforcement during events. Video mapping can be used to produce a similar by higher-end effect.

Guide Number: Guide numbers are used as a rating system to gauge the power or range of flash. The guide number equals the distance x f/stop. For example, say your flash has a guide number of 80. At ISO 100, to determine the proper exposure for a subject 20 feet away, multiply 20 by X number (in this case 4) to get 80 (the guide number). Setting the aperture to f/4 (80 = 20 x 4) will render a proper exposure (at ISO 100).
