The Lowel SoftCore Fixture Without Lamphead is the basic unit of their SoftCore system of compact fluorescent lighting fixtures, which accept the Lowel Rifa eXchange FLO-X lampheads (not included). The quick exchange feature means you can rapidly change from the FLO-X1 (1 fluorescent tube) to the FLO-X3 or FLO-X5 (3 or 5 tubes, respectively), and the unique 4-arm design of the fixtures makes softboxes quick and easy to attach and rotate. When used with Lowel's 80W high C.R.I. fluorescent lamps (not included), SoftCore fixtures deliver soft, accurate constant-source daylight. This is the fixture alone, without lampheads or lamps. A 16' T1-80 AC cable is included.
