The CR series flash is an innovative trial design of a new type of lamp for digital photography in a studio setting. It is mainly embodied in the change of structure and concept of design. The interface of the lamp holder is 24mm bigger than the EH series, which is 118mm. In addition to the large luminous tube used by this series of flash, we designed the input of the modeling lamp to 100% all along, which makes it possible to use integrated high efficiency, energy saving bulbs rather than professional halogen bulbs. It can obtain a continuous light source of 5500-6500K color temperature.
