I daresay that with a bit of re-design the SC circuit could be made to
operate from 6V, however for your portable function as a torch the pcb
is rather large. You could take a look at the Zetex range of drivers
http://www.zetex.com/3.0/a1-7b.asp and look at the application note
for the 5W star driver. Of course you will have to do the work to get
it built and working. Remember that a 5W Star needs a fairly large
heatsink.
