Wiring Luxeon 1 emitters?

[digitalshooter]

I have just purchased 8 Luxeon 1 emitters (LXHL-BW03) to use as accent lights in my home. Spec sheet: http://www.lumileds.com/pdfs/DS25.pdf . If I understand correctly, they are 350mA and 3.42V.

Unfortunately, I am a complete novice when it comes to understanding what is required as far as the size and type of resistors, power supply, series or parallel configuration, etc. I am fairly decent at soldering and figuring the logistics of the creation, but not at the electrical calculations.

I would like to be able to power all 8 if possible from one transformer. Any ideas would be appreciated.

Thanks,
PH
