"At 2 - 3 Amps most power diodes exhibit slightly more than 0.6VDC drop 
so 4 in series would approach a 2.5V drop.  The diodes will still 
generate some heat, but not as much as a resistor."

Actually, the diodes will dissipate exactly the same heat as resistor(s) 
dropping the same voltage at the same current, unless the diodes are 
LEDs and thus converting some of the energy into visible light :-)
