Nope. But if you use the flash in auto mode, it sets output automatically, so it's not a problem. In auto mode, you can stop down or open up the aperture for exposure compensation.
In manual mode, you can always stop down or use an ND filter.

Flash units usually put out more light, have better color temperature, and they freeze action. Some also claim that LED lights add a weird color shift with digital cameras, but I don't know about that. But, a continuous LED light could be handy for focusing in low light.
