This uses exactly the same coiled tungsten filament but it burns at a much higher temperature in halogen gas. Consequently, these lamps maintain virtually the identical light output and color temperature throughout their life; they also last longer than traditional lamps and are smaller with regard to their equivalent wattage. Available wattages range from 200 to 10,000 and the most powerful are intended for cinematography; the highest normal wattage for still photographic lights is 2000. The light output is the same as that from a new tungsten lamp of traditional style with the same wattage chroma keying. The newer development, particularly relevant to photography, in which camera’s white balance settings may take care of color differences, is high-performance fluorescent. The lamps used are flicker-free, nearly as bright as tungsten, colorbalanced for 5400K or 3200K, and cooler and less expensive to run.

Every incandescent light needs to be fine-tuned to have the best results. Usually, it carries its very own light housing that incorporates some kind of reflector behind the lamp. This is partly to make use of all the light radiated and partly to control the beam. The deeper and more concave the reflector, the more

concentrated the beam as it is harder to spread a beam that is already tight when it leaves the housing compared to concentrate a broad beam. green screen backdrop The most general-purpose housing has reflectors that give a spread of between about 45 and 90 degrees.

Used alone in the studio, tungsten lamps simply need 3200K incandescent white balance. However, tungsten lighting is frequently used on location and in

interiors. However, this is often used in combination with existing lighting, like daylight and fluorescent light. As a result, lighting filters are typically used for converting the color temperature or for correcting the color to that of fluorescent lamps. You could, however, use mixed lighting and post-production methods but it is best to get it right at the shoot. Visit‌
