Hi Neil,

I'm sure Chops will be able to add something, he's got
a lot of experience in flashlights. But definitely you
should check out lithium-ion batteries and white LEDs
and LED controllers. dealextreme.com is a good source
for that, prices are low but drop-shipping takes a
couple of weeks(or longer right now since it's lunar
new year).

Cheerful regards,

Bob
