This is a Lowel Rifa-Lite EX55 Softbox Light. This softbox opens like an umbrella and its removable front diffuser measures 21 x 21" (53 x 53 cm).
Compact, lightweight, and self-contained, the Rifa-Lite uses a simple design approach as old as the umbrella to achieve its quick and easy setup and strike capabilities. The EX series of Rifa-Lites enables you to change out the fixture's socket to make use of cooler-running fluorescent bulbs.
A state of the art, woven glass fabric, heat-resistant 21 x 21" (53 x 53 cm) front diffuser provides sufficient illumination with soft shadows.
Accepts bulbs of different wattages and voltages, with the appropriate adapter(s).
Compact folded size (17") allows it to fit into many of Lowel's smallest location light kits.
