Why is there only 150W in the 400W photographic lamp? Is there 250W left in the flash tube? For example, Jinbei EC400.

If it's a studio flash, there should be a modeling light. Most studios are almost completely black, because it is convenient to distribute light and observe the light effect. If there is no styling lamp, it will be discredited. I can't concentrate. The modeling light is always on, and the flash is energy storage. Charge every time it flashes. When the 400 is fully opened, it will release 400w of energy, and whether there is a modeling lamp or not, it will release 400w. There are too many tiles in the modeling lamp, which should catch fire. I touched 150w with my hand, and it was almost burnt.
