How many photographic lights are commonly used in e-commerce photography?

I use U2 myself, 1 300W, 2 400W, 1000W. To illustrate this point, you have to do a lot of work and shoot a lot of things before you can use 1000W, otherwise it will be absolutely overexposed. 30-40 planes, 400W is enough. If you add background frame, shaft, lamp holder, cloth and honeycomb, it will cost about 5000 yuan.
