The listed Wattage is a minimum figure, you can use a higher rated resistor.

Led's not worth using where omitted. The K2's listed are the high current ones. The reason some K2's have a lumens range is that they come in different versions.

I used recommended average parameters. Most of the led's could be driven past these settings.

There is a new updated chart here

P4 info...

Use this info to calculate correct resistor or just use a buckpuck.

Red
mA max 800

Green
mA max 1000

Blue
mA max 1000

For Forward Voltage look at the very last digit on the back of the star and compare it to this chart.
