The professional Falcon Eyes studio flash TF-401 with 400Ws flash power provides everything a professional photographer needs. Everything is there: quick charging time, robust metal housing, professional bayonet connection for accessories, fan cooling and a built-in slave receiver. Thanks to the digital display, the studio flash can be adjusted accurately. The modeling lamp can be turned on and off and can be adjusted proportional with the flash power. Furthermore, the studio flash has an auto dump function. This means that when the output power is reduced, the power will automatically be discharged.
