The Interfit Super Coolite 455 Twin Head Kit produces the equivalent of 900 watts per head of Tungsten lighting from the included energy efficient near daylight balanced lamps and is a powerful addition to the popular Super cool-lite range. Each head allows you to control the lighting in two switchable banks per head. This allows you to control lighting ratios and contrast with ease. With the addition of two 70cm 27” Octoboxes, the Interfit Super Coolite 455 Twin Head Kit is the perfect product for portraits or for product photography when near shadowless lighting is required. The INT293 kit includes an educational DVD to help you though the set up and how to use Fluorescent lighting to achieve great results.
