LED #1 is a 1 watt LED rated at 3-4 Vdc at 350/700 mA

LED #2 is a 3 watt LED rated at 2 Vdc at around 350/700 mA

According to Resistor calculations, I get:

LED #R1 = 4.7 Ohm, 2 Watt rating (for 700 mA)

LED #R2 = 8.2 Ohm, 4 Watt rating (for 700 mA)

The problem is I can't find any online vendor that sells common resistors at these specs. Am doing the calculations wrong to arrive to 2 and 4 watt rating or is there a vendor out there that sells these? Alternatively, is there a unique type of resistor that I can substitute for these ratings?

Thanks for any info.
