What's the difference between a photographic lamp and a searchlight on location?

hehe, there is a big difference. Photographic lamps are professional lamps, and their color temperature is strictly controlled. Generally, photographic lamps have two color-coded cold light sources and low color temperature lamps, that is to say, the cold light source is 56k, and the low color temperature is 32k, while ordinary lighting lamps do not care about the color temperature.

Photographic lamps for outdoor use generally belong to cold light sources, and the light emitted by the high color temperature of 56k is very close to the white light in the daytime sky, so they are used for outdoor use and searchlights. Not necessarily.

Cameras, cameras and camera lenses are very sensitive to the color temperature, and even a slight change in the color temperature can be sensed, so photographic lamps can't be replaced by ordinary lighting fixtures.

You're right. It's all about improving the brightness. For human eyes, machines will not be so humanized.
