Interfit's Super Cool-lite 4 55 Two-Head Fluorescent Kit not only gives you soft, cool light in a compact kit, it uses 1/4 the energy of tungsten lights. The two Super Cool-lite heads each hold four 55W fluorescent bulbs balanced to "near daylight" 5200K. This 220W is equivalent to 900W of tungsten light, so the kit delivers a powerful 1800W of light without the heat. The two included 27" (70 cm) Octoboxes are ideal for the soft, nearly shadowless light often used for portraits and product photography. Two light stands, 2 power leads, and an informative educational DVD round out the kit.
