Answer:

Camera flash units charge a capacitor and then discharge it through a light bulb. When the unit flashes, the energy stored in the capacitor is released in the form of radiant energy (a flash of light). Flash units waste some of the energy in the form of heat, so is an upper limit for estimating the radiant energy.
