ha.. Im even 'more' confused! (but thanks for the reply/response!) 
I didnt think it would be this hard to use a common ANODE high-powered led..
Im trying to take it all in and (understand it)...lol..
So I can use the transistors.. but would need a huge resistors in it.. (which would be using/losing lots of power as heat...yes?)
(dont want that).. although.. to be fair.. the leds will NOT be on constantly very much if at all.. you can either press button and blink manually.. or switch over to 'auto-mode' and you hold down the button..and it rapidly blinks the led..
but those seem like HUGE resistors..and not ones easily purchased at your local radioshack..etc.
still unclear about npn vs pnp? and this current sinking vs current sourcing..
gonna search around some more see about how others have done high powered led + Arduino stuff..etc.
thanks
