This is a Lowel Rifa-Lite EX55 Softbox Light
with lamp. This softbox opens like an umbrella. 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.
