The big advantage of strobes is not just triggering convenience—it’s that they deliver a huge amount of light in a very short burst. That makes them far more effective for photography than practical continuous lamps.

Key benefits:

• much higher effective light output: a strobe concentrates its energy into a brief flash, so matching that with continuous light would require enormous power
• freezes motion: the flash duration can stop subject movement and even reduce blur from small camera shake
• less heat and discomfort: continuous lights bright enough to compete would be very hot, power-hungry, and uncomfortable for subjects
• easier to achieve studio looks: very bright flash output helps overpower ambient light, light large scenes, or create clean white backgrounds and controlled dramatic portraits

So while continuous lights are useful, they usually can’t match strobes for raw photographic lighting power, motion stopping, efficiency, and comfort. In studio photography, watt-seconds on strobes are useful because the light is delivered in a burst; comparing that directly to household or general-purpose lighting specs is not straightforward.
