Contrast Ratio is the brightness ratio between the brightest white and the darkest black within an image. A ratio of 300:1 means the brightest point in the image is 300 times as bright as the darkest point. If there is larger difference in brightness, contrast ratio will be higher.

Tungsten Light is also called as incandescent light. This is the light from an ordinary bulb having a thin coiled tungsten wire that emits light (becomes incandescent) when an electric current passed throw it. Colour temperature of Tungsten is around 2800K to 3400K.

Fresnel is a light having a lens with raised circular ridges on its outer surface. The fresnel lens is used to focus the light beam.

Incandescent lamps will produce heat until it glows as tungsten filament will be heated due to passing of current through it. The glow is caused by the filament's resistance to the current and is called incandescence.
