Angstrom - An angstrom, angström, or ångström (symbol Å) is a unit of length. It is not an SI unit. It is accepted (although discouraged) for use with the SI. It is used sometimes used expressing the size of ato. Used . ms, and lengths of chemical bonds and visible-light spectra.
The ångström is named after the Swedish physicist Anders Jonas Ångström (1814–1874), one of the founders of spectrosc. Used . opy. Besides astrophysics, Ångström was also a student of heat transfer, terrestrial magnetism, and the aurora borealis, which was so prominent for him in his northern skies.

Scoop Light - Scoop lights or Scoops are circular fixtures that do not have any lenses. They have a reflector at the back of the fixture that directs the light out of the fixture. Since they do not have any sort o. Used . f lens system they are cheaper than other fixtures. However, the downside of this makes it so that you can not focus the light at all (even PAR's allow for more control than scoops). . Used .
Discharge Lamp - A high powered light source produced by an arcing electrical discharge between two electrodes suspended in a glass tube filled with gas, usually high or low pressure sodium gas, xenon, mercury vapor, .
