My concern was whether this really lamp provides enough light when shooting video indoors and if the LED light can produce any fine tunings and if you have to study computer science to operate. My first record I've done in a room with green screen. The light would have been at 100% power too much, the lamp brings so neat light output. A green screen must always be evenly illuminated - also worked well. The light output can be adjusted with the included remote control. The LED with 3200 K and 5500 K with can be set in your performance individually in small steps. This one has the ability to accurately adjust the brightness and still has options to adjust the hue - photographs and video recordings are illuminated very nice for my taste. The packaging is small and I do not have much room for large lights, so even a plus, especially if you have to transport your equipment. The installation on a tripod are professional ways of illumination. For moving lighting design is a handle for the light with us. The lamp can be operated with the power supply, then you have the two battery left - for example, for the second lamp YN-300 !!!!! for which one would have to buy an extra battery anyway - Super. To illuminate it anyway requires 2 or better 3 lamps. The controls are simple and the device more easily by remote control without too much time reading the manual and works instantly. I am happy.
