In photography creation, what are the advantages of long-bright photography lamp and flash lamp respectively?

Advantages of long-bright photographic lamp flash

Long-bright photographic lamp flash is light and easy to move, and can be powered by battery or power supply, which is very convenient. The color temperature of the flash is generally accurate, and some constant light sources can adjust the brightness steplessly, which is relatively easy to use.

Disadvantages of long-bright photographic lamp flash

The flasher does not flash or shine, and the success rate of flashing is affected by the quality of the flasher and the distance of flashing. In addition, there are photographers nearby, and they may accidentally flash into other people's lights when shooting. ?

Reflective surfaces of other colors will change the color temperature and easily cause white balance errors, while dark surfaces will attract a lot of light, which is not conducive to reflecting light.

It is suggested to use white plastic foam board (you can buy it from the decoration market, or you can choose flat foam board directly from various household appliances packaging boxes) as a movable reflector, which has a soft light effect when filling light, and the actual use effect is very good. ?
