[Closed] One for the lights people

Which cheap lights are readily available, burn brighter than the sum and last forever?

Failing that, what can I pick up for less than £50 from somewhere like Deal Extreme than has a 2-3 hour burn time and will be as bright or brighter than the pair of 3 year old CREE Romisen torches I currently have strapped to my helmet.

The two torch approach works okay with about 1.5 hours per torch on CR123 rechargeables but if I run both torches together I don't get much of a ride and if I run them individually things get a bit sketchy when I speed up.
