drats, from what I understood the LPD8806 on that rpg strip handled the current. As for the two high power led's I am just planning on running them on a logic level mosfet until I get a constant current driver.
I don't see where you linked to the LPD8806 strip. But yes, most do handle the current on their own. It's only with high power LEDs (like the 3W LED you have linked) that it becomes impractical to use current limiting resistors.
In general though, I think rpg strips are too dangerous to deal with.
