The power of the Godox QT1200IIM can be precisely set from 1/128 to 1/1. This flash is characterized by a very short recycling time. The 150W modeling lamp of the flash unit is also adjustable for better pre-visualization of the final effects. It can be set from 5% to 100% of the power or simply turned off. The impressive functionality of this studio flash includes strobe mode, HSS, color temperature stability mode, and an integrated X System receiver. Godox QT series flashes are available in various power versions, up to 1200Ws. They are characterized by a flash power adjustment range of up to 7 f-stops (1/1 - 1/128, with 0.1 EV precision). The flash recycling time at full power is less than 0.9 s. At minimum power, they achieve a very short flash duration of only 1/28984 s, which offers a lot of freedom during photo shoots. The flash color temperature is 5600 K and can fluctuate by ± 200 K depending on the set flash power. The flash has several operating modes, but the color temperature stability mode certainly deserves more attention. The built-in X System receiver allows remote triggering of the flash (up to X-Sync time), changing flash power and mode. In addition, the QT1200IIM has a USB port for connecting XT16, FT-16 or X1 TTL system receivers. It can also be connected to triggers from other brands via the 3.5 mm jack input port. The panel on the back of the flash is very simple, readable and functional. The LCD screen on which the flash settings are displayed is readable even from a rather wide angle. Next to the screen there is a practical knob for adjusting the flash power, for changing the radio communication channel and for changing the flash groups. The series of five buttons below the LCD screen allows quick access to all flash settings and functions. The 150W halogen modeling lamp can operate independently of the flash power (manually adjustable brightness) or be linked to the flash power (proportionally). The modeling light can be automatically turned off for the duration of the flash or remain on without interruption. With this flash, various types of light modifiers can be used such as: reflectors, softboxes, snoots, beauty dishes and others equipped with a Bowens mount.
