About the Interfit Photographic EXD400

The Interfit EXD400 Digital Flash Head (110V AC) is another step forward in the evolution of the EX flash system. The lightweight, economical monolight gives you a total of 400W/s of power, with precise power adjustment in 1/10 f-stop increments and a 6 f-stop range, providing excellent control over your lighting. Fan-cooling extends the life of both the 100W modeling light and the user-replaceable flash tube. A built-in slave cell responds to flash or to the optional infrared transmitter and audible and visible signals alert you when the flash is fully recycled.

It even has a program that overcomes the problem of pre-exposure flash from a camera setting off your flashes prematurely. The EXD400's Auto-Dump feature discharges extra power in the capacitors, the second you turn down the power. The EXD400 comes with an umbrella reflector, built-in ergonomic handle and a flash tube transport cover.
