...Pattern is the shape, evenness and quality of a lamp's output. The pattern of light that a device produces is largely determined by three important factors. The first of these factors are the specifics of the bulb, the reflector and lens assemblies.

Color temperature of light is measured in kelvins. Gel color lights are organized by various systems that are maintained by the color manufacturing companies. The labels given to the gel color lights depend on the gel color used, but also the power level the lamp will be run at.

The tungsten filament in the bulb glows orange rather than white as the percentage of full power slowly runs down. This is what is known as amber drift or red shit. IN a 1,000-watt bulb at 50% capacity, will appear much more orange in color than a 500-watt bulb at full capacity.

The intensity of light is measured in both lumens and lux. For any given luminaire the design of the instrument, as well as the presence of gobos or color gels, the distance form the area to be lit, the neuro-optics of the overall scene and the power of the bulb are all taken into consideration when figuring the intensity of a light or lighting set-up.
