XGA - Extended Graphics Array is a standard computer display introduced in 1990 by IBM. The initial version of XGA built upon IBM's VGA, adding support for two resolutions, 800 × 600 pixels with high color . Used . and 1024 × 768 pixels with a palette of 256 colors. XGA-2 was developed later and with 1024 x 768 pixels with high color, and 1360 x 1024 with 16 colors. However, all XGA modes have an aspe. Used . ct ratio 4:3 rounded to 8 pixels....
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 . heat. They are illuminated by the movement of electrons in a semiconductor material and last as long as a standard transistor.. Used . ...

Pattern - Pattern refers to the shape, quality and evenness of a lamp's output. The pattern of light an instrument makes is largely determined by three factors. The first are the specifics of the bulb, reflecto. Used . r and lens assembly. Different mounting positions for the bulb (axial, base up, base down), different sizes and shapes of reflector and the nature of the lens (or lenses) being used can all a. Used . ffect the pattern of light. Secondly, the specifics of how the lamp is focused affect its pattern. In Ellipsoidal Reflector Spotlights (ERS) and their derivatives (see below), there are two beams of light emit...
