Default resister/s needed to end up with the proper power levels.

ok for all you electronic brainers.. I have a transformer that take 120 AC and goes to 18VDC / 80 mA

for a LED I need to step that down to 4.5Vdc and 20mA. so I need to limit both the curent and the voltage. it is easy for me to to limit one.. but maby I am not looking at it right .. or I am having a brain fart but it is confusing me at the moment.
