Features: It supports remote controlling with remote controller, wireless controlling with mobile phone ( supports Android 4.3 and BT4.0 version and above IOS7.0 and iPhone4S and above mobile phone ) and group controlling the luminous intensity of YN300 III etc. YN300-III adopts 300 high-quality 5500k color temperature of lamp bead, the brightness is higher, the light spot is more evenly and the service life is longer. YN300 III is equipped with multi channel wireless remote controller which is used to adjust the luminous intensity and control the switch of YN300 III. Furthermore, it is very convenient to use this controller to control the luminous intensity and the switches of 8 groups of video lights. A mobile APP is provided on our official website. With this mobile APP, you can control this LED video light with your mobile phone, read the current parameter of the luminous intensity and channel, and, control the luminous intensity and the switches of 8 groups of video lights individually. You can control your LED video light as needed. YN300 III adopts YONGNUO proprietary LED driving technology which does great help to effectively avoid corrugation and stroboscopic flash. YN300 III adopts encoder digital dimming system, including coarse tuning mode and fine tuning mode. On the LED digital display screen of YN300 III, the parameter of the power output is intuitional. Shooting for long time is possible because YN300 III supports external DC power input (power adapter is optional). YN300 III, equipped with 2 pieces of color temperature filters, can be used under different circumstances.
