555 timer, Buckpuck, and Luxeon rebel

[The Yin]

Hello all,
I'm working on a slightly different project, but using extra parts from saber building.
I've got plans for a Blaster and I want to use a 555 timer for the trigger setup so I can hold down the trigger and have the LED flash as a firing effect.
So' I've been reading up on how to wire a 555 timer and I've just about got it all figured out, but now I've just read that the output of a standard 555 Ic is 200mA.

The idea I had was to connect a BuckPuck (700mA) to the 555 ic and power the Rebel Star (red-orange) from the BP. But, if the 555 only puts out 200mA, what does that mean for the BP?
I'm not sure if I'm understanding the whole Voltage to Amps relationship in this setup.

Please help, this level of electrical engineering is uncharted waters for me.


UPDATE:
I may have found the anwser: http://www.555-timer-circuits.com/in...t-current.html
I just not sure of inner workings of the buckpuck and how it may fair in this setup.

Update 2:
Or maybe THIS (http://www.theledlight.com/pdf/Drive...plications.pdf) is what I'm looking for.
