These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black-Light lamps: Black light lamps give off long-wave UV-A radiation of around 350-400 nm. They are often used to attract insects to traps.
Slower shutter speeds (typically from 1 ⁄ 10 to 1 ⁄ 50 of a second) were initially used on cameras to ensure proper synchronization and to make use of all the bulb's light output. Cameras with flash sync triggered the flashbulb a fraction of a second before opening the shutter to allow it to reach full brightness, allowing faster shutter ...
A light shelf is a horizontal surface that reflects daylight deep into a building. Light shelves are placed above eye-level and have high-reflectance upper surfaces, which reflect daylight onto the ceiling and deeper into the space. Light shelves are typically used in high-rise and low-rise office buildings, as well
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
Like all light bulbs, the number represents the diameter of the bulb in 1 ⁄ 8 of an inch. Therefore, a PAR 16 is 51 mm (2 in) in diameter, a PAR 20 is 64 mm (2.5 in) in diameter, PAR 30 is 95 mm (3.75 in) and a PAR 38 is 121 mm (4.75 in) in diameter.
Some of the least pleasant light comes from tubes containing the older, calcium halophosphate phosphors (chemical formula Ca 5 (P O 4) 3 (F, Cl):Sb 3+, Mn 2+). This phosphor mainly emits yellow and blue light, and relatively little green and red. In the absence of a reference, this mixture appears white to the eye, but the light has an ...
