The Impact SF-AE56 AC Flash is a handy light source that screws into any household fixture, E26 socket or photo fixture with an E26 (Edison) base. A jack-of-all-trades, the 5,600K SF-AE56 can be used in lamps or home fixtures when lighting interiors with flash, especially during the daytime. Make your own super-lightweight portable flash kit with an optional Impact Porcelain Socket with Umbrella Mount (IMSPUM). Use it as a background light, hair light or accent light. The SF-AE56 can be used in either the master or slave mode thanks to its optical sensor and sync outlet. Trigger it from the camera via the included 15' 3.5 mm mini jack sync cord or trigger several of them as slaves responding to the camera's master flash.
