These adapters allow to use electron flashes (aka speedlights) as a light source for GuerillaBeam projectors. This allows to use them like the famous Image Fulgurator or the Light Blaster™. Like all GuerillaBeam light adapters, it can be screwed into the gBeam slide holder and combined with any 35mm lens. There's one adapter for the Canon 430EXII, and two others that are designed to fit any flashgun with a head that's at most 42mm thick. With all adapters you'll need some duct tape to fix the flash to the adapter.This adapter need supports. Sorry for that.
