Since I have no real studio, I was able to test the lamp only at home with friends, but it provides remarkable results. (See photos attached)
What more is there to say:
1750Watt performance with 350Watt power consumption is good and the only energy-saving lamps are probably 2/3 of the price value. I recommend not to get anyone the Jinbei Boom Stand to (excl. Rolls) and you've got definitely enjoy photography.
In this sense, good light!
