Artificial light

The test for colorfastness to artificial light Kenon arcfading lamp test ISO 10S-B02, is identical to BOl except that the sample is exposed to xenon arc light under prescribed conditions in a closed container. 

Ammonium reineckate (Reineckate salt) [13573-16-5] M 345.5, m 270-273 (dec). Crystd from water, between 30° and 0°, working by artificial light. Solns of reineckate decompose slowly at room temperature in the dark and more rapidly at higher temperatures or in diffuse sunlight. 

Motion detectors and daylight detectors reduce artificial lighting use, reducing summer cooling loads. 

Rapidly degraded under artificial light. DT50 30 h (pH 5 at 20°C).

In the case of laying hens natural light may be supplemented by artificial means to provide a maximum of 16 hours light per day with a continuous nocturnal rest period without artificial light of at least eight hours.

Most tight sources for artificial lighting have a UV component in their emission spectrum. Usually, the glass encapsulation absorbs all radiation below about... 

It responds well to a wide range of hydrocarbon fires and is blind to welding arcs except when very close to the detector. It can see through smoke and other contaminates that could blind a UV detector. It generally ignores lightning, electrical arcs and other forms of radiation. It is blind to solar radiation and resistant to most forms of artificial lighting. 

These significant findings form the basis of a set of design principles for the construction of molecular photovoltaic cells and other nanoscale electronic devices in which the control of both the rate and directionality of ET processes is an essential requirement. The successful construction of an artificial light-driven proton pump, based on principles of long-range ET processes illustrates the promise of this approach.1501... 

Immature female Wistar rats (15 days old) were housed individually in wire mesh cages with solid floors. Artificial light was maintained as a 12/12 h light/dark cycle under standard humidity and temperature conditions. Animals were weaned on conventional standardised laboratory diets. Diet and water were available ad libitum. All animals were acclimatised for 24 h before their injection. The study was conducted in accordance with the OECD Good Laboratory Practice Procedures [21].
