The EH series flash, with its flowing and fashionable design incorporates step-less light adjusting technology, and can change the light output from full to 1/8 light (within the range of three stages apertures). The buzzer and multi-system modeling lamp (intense light professional halogen lamp), make the photographic process more convenient. This high-power flash, with its strong light output, ideal color temperature and high light stability, is the first choice of professional advertisement studios and high-class photo studios. The K series includes seven models (from EH-300K to EH-2000K). The K series flash has conquered the difficulty of high-power flash long flashing duration. We have decreased the flash duration to 1/1000-1/3000s from the former 1/300-1/500s, which not only fulfills the high-speed synchronization requirement of professional photography, but also improves the sharpness and contrast of photos.
