The problem of photographic flash

It is cheaper to buy a constant light with higher power and a color temperature of about 5500k K.

It also depends on what style of photos you want to take. As far as lighting is concerned, it is best to choose above 600W W, because the color temperature is generally 300w in Yi Deng and 250w in two lamps, so children's photography generally does not need 400w and 600 W.
