The new and improved Spiderlite TD6 is the industry's most powerful compact fluorescent lighting system on the market today. This kit comes complete with two heads and twelve 50-watt daylight balanced fluorescent lamps offering over 2400 total equivalent watts of power. The Spiderlite TD6's all metal construction insures years of quality of durability. Three newly designed low profile switches on the back of the Spiderlite TD6 operate 2 lamps per switch and can be easily turned on and off to control light output (without changing color temperature). Newly added, an inline cord switch allows for powering on and off the main unit when lights are placed up high and difficult to reach. The mounting stud attached to the Spiderlite TD6 offers extra durability and ease of insertion into the included tilter brackets. The BUILT IN ADAPTER RING allows for quick and easy mounting of the included 24" x 32" softboxes offering diffusion and control of your lighting. Rotate the softboxes 180 degrees with the attached handle and lock-down turn knob. To complete the setup, included are two 10' heavy-duty light stands and deluxe wheeled travel case. Actual Meter Reading (AMR) = F8; Shutter Speed 1/60; Distance 3'; ISO 400; mounted to a 24" x 32" softbox using the 6-pack Westcott 50-watt Daylight Balanced Fluorescent Lamps.
