I'm going to try the above power supply and see what happens. My desire is driven by curiosity more than need or thrift, so the budget is OK.

easy way to add over-discharge protection?

improving cheap chinese bike light?- help please
I bought some cheap bike lights. One has 4 emitters in a round barrel, the other has 5. They each claim Cree XML-T6 emitters. Both seem to work pretty darn well. They don't get terribly hot though.
