Powering a LED light with 12VDC power supply

[eljainc]

Hello,

I am planning on using a 12VDC power supply to drive an LED. However the
LED is rated for 1.5V and about 20mA current. Is there a circuit that is recommended
for this purpose? I know I can put a resistor (560 Ohms) in series with the LED to
limit the voltage, but is there a better way to do this?

Thanks
