A photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation.Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does.

Since the IGBTs switch on and off at a regulated cycle rate, a generator can be slightly off-speed and the lamp will still be flicker-free, which is not the case with a standard magnetic ballast. The square wave nature of the output results in a straight-line power output from the lamp.
A twilight switch is an electronic component that allows the automatic activation of a lighting circuit when natural light drops in a given environment. Among a large number of uses, the most common is to enable automatic lighting of streets, roads, highways, roads, gardens, courtyards, etc., when sunlight drops below a certain level (e.g.: a ...
Gouache (/ ɡ u ˈ ɑː ʃ, ɡ w ɑː ʃ /; French:), body color, [a] or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), [1] and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a long history, having been used for at least twelve ...
Fugitive pigments are impermanent pigments that lighten, darken, or otherwise change in appearance or physicality over time when exposed to environmental conditions, such as light, temperature, humidity, or pollution. [1] [2] Fugitive pigments are present in types of paint, markers, inks etc., which are used for temporary applications.
A trouble light using a compact fluorescent lamp. From top to bottom are a hook, a cage, the switch and a handle in one molding. A trouble light, also known as a rough service light, drop light, or inspection lamp, is a special lamp used to illuminate obscure places and able to handle moderate abuse.
The initial prevalence of analog sticks was as peripherals for flight simulator games, to better reflect the subtleties of control required for such titles. It was during the fifth console generation that Nintendo announced it would integrate an analog stick into its iconic Nintendo 64 controller, a step which would pave the way for subsequent leading console manufacturers to follow suit.
Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and commercial availability. [3] Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength ...
