filament
a single continuous strand, fiber or thread.
fill
the illuminate material in a UV lamp that is activated by energy; typically mercury, although other elements are also used; refer to weft.
Tungsten filament - artificial light source using a tungsten filament contained within a glass envelope.
Tungsten Filament
A lamp coil that emits light (and heat) when electricity flows through it. See: Incandescent Lamp and Tungsten-Halogen Lamp.
-Opal lamp is a filament lamp with an opal glass bulb for optimum diffusion.
-Opalotype is an obsolete printing process in which a carbon-process image is transferred on to translucent opal glass.
A quartz lamp is a short tube of quartz glass, housing a coiled filament that runs the length of the tube. In ordinary tungsten lamps, the tungsten evaporates from the filament and settles on the glass and gradually darkens the bulb.
Tungsten-Halogen Lamps Tungsten-halogen lamps have a tungsten filament inside a quartz envelope. This type of lamp does not blacken the inside of the envelope and operates at an almost constant brightness and color temperature throughout its life.
Molds are tiny, multicelled organisms made up of branching filaments called hyphae (singular: hypha). Some of the hyphae are embedded in the material on which the molds grow and are called vegetative hyphae.
Later, magnesium filaments were contained in flash bulbs, and electrically ignited by a contact in the camera shutter; such a bulb could only be used once, and was too hot to handle immediately after use, ...
Tungsten lights, first a definition, tungsten lights have a filament and the filament is inside a bulb; the light bulbs in your house are tungsten lights.
Halogen An incandescent light bulb that contains a tungsten filament. Emits light with a higher color temperature than an incandescent bulb.
Quartz iodine lamp
Is a compact tungsten filament lamp designed to maintain its colour temperature and light intensity throughout its working life.

Incandescent lamp
An electrical lamp in which the filament radiates visible light when heated in a vacuum by an electrical current.

Photolamp (3400K).
Photographic lamp giving more light than a normal lamp of the same wattage, at the expense of filament life. Often referred to by the trade mark Photo Hood. Are used with type A colour films.

Tungsten film is used under studio lights, known as hot lights (because they get real hot), which use tungsten filaments. These are similar to, but not the same as regular incandescent light.
an electronic timer, times as short as one- tenth of a second can be used. However, such short times have little quantitative significance for calculating relative exposures because they are shorter than the warm- up time of the light- bulb filament.
