By including two smoothing capacitors (with resistor in between), it reduces stress on components. Smaller watt values can be used.
This is the most reasonable solution consistent with the original requirement. However, I believe that the values are not optimized and the actual values can be tweaked for the desired output.
A high value resistor (say 100K- not computed) may be connected in parallel with C1 and a surge protector may be used for better performance.
