Then it would run at half brightness as the LED only conducts through half the cycle. With a half wave rectifier you need twice the current to get the same intensity as you would with a fullwave rectifier or DC.
It's also a good idea to fit a 470k to 2.2M bleeder resistor across the capacitor to discharge it when you disconnect the power.
