Subtractive Color - Subtractive color explains the theory of mixing paints, dyes, inks, and natural colorants to create colors which absorb some wavelengths of light and reflect others. The color that an object appears t. Used Wholehog III. o have is based on what parts of the electromagnetic spectrum are reflected by it, or conversely by what parts of the spectrum are not absorbed.
Anything that is not . Used Wholehog III. additive color is subtractive color. No other color mixing systems are known, except the imperfect system resulting from mixing real pigments, something that is very confusing nowadays.

Lumen - In physics, specifically photometry (optics), the lumen (symbol: lm) is the SI derived unit of luminous flux. It is the amount of light that falls on a unit spherical area at unit distance from a sour. Used Wholehog III. ce of one candela. In steradians this is equivalent to the amount of light that falls on a unit solid angle from a light source of one candela. Alternatively, one lumen is the tot. Used Wholehog III. al light produced by an isotropic light source of (1/4p) candelas. A 100 watt incandescent light bulb will output around 1500 lumens. ...
LED - An LED or light emitting diode is simply a tiny light bulb that fits into an electrical circuit. However, unlike ordinary bulbs, LEDs don't have a filament that will burn out and generate very little . Used Wholehog III. heat. They are illuminated by the movement of electrons in a semiconductor material and last as long as a standard transistor.. Used Wholehog III. ...
PAR - PAR is an acronym referring to "Parabolic Aluminized Reflector" which describes the mirror configuration. PAR lights resemble car headlights. They possess a lens, but the lens is an integral part of t. Used Wholehog III. he lamp and its position relative to the filament canno . Used Wholehog III. ...
Ethernet - Ethernet (this name comes from the physical concept of ether) is a frame-based computer networking technology for local area networks (LANs). It defines wiring and signaling for the physical layer, an. Used Wholehog III. d frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEEs 802.3. It has become the most widesprea. Used Wholehog III. d LAN technology in use during the 1990s to the present, and has largely replaced all other LAN standards such as token ring, FDDI, and ARCNET. ...
