Which is better to shoot clothes, a constantly on camera lamp or a flash? Ask god for help

Still life can be hung with a normal bright photographic lamp, which is more convenient to work. But it must be a professional photographic lamp. Ordinary energy-saving lamps, however powerful, can only be more dazzling, and there are many colors. The professional measure of lighting is not how exciting it is in how bright, but its color rendering index. Some lamps are not too dazzling and have low power, but have high color rendering index, so the objects illuminated by them can present very thick and clear colors and outlines. Some lights are very strong and dazzling, but they are very vague and weak when they shine on objects. If the model wears it to shoot, it is best to decorate the studio with a flash. For professional models, flash can stimulate and mobilize their sense of existence and desire for expression in front of the mirror more than a constant light source.
