The Elinchrom 27 x 27" (69 x 69 cm) Rotalux Softbox is designed for the exclusive use of Elinchrom flash heads. The featherweight box features a matte-black crinkle exterior with distinctive gray rip-piping and a reflective silver interior. The shoot-through design uses both a removable internal baffle and removable, flush-mounted front face to soften the light. Another innovative feature which distinguishes Elinchrom softboxes from others is the lightweight dedicated speed-ring, which utilizes knurled, spring-action sockets to connect the four stainless rods which form the frame of the box, to the ring. This allows easy assembly of the box in a de-tensioned state. The user then simply pivots the sockets 90 degrees until they lock into place to tension it for use. As a further convenience Elinchrom provides a durable, dot-patterned nylon case with a flat bottom designed to hold the de-tensioned Rotalux without dissembling it. The square 27 x 27" (69 x 69 cm) shape is ideal for portraiture or for use as a fill light.
