... twice as bright as a 25 LED lamp and only four times brighter than one with 5 LEDs. (Doubling the perceived brightness requires quadrupling the optical power).
I bought a 40 White LED flashlight and it's so bright you can't look directly at it unless you're a masochist.
Valveman ;D
Otherwise, if you don?t want to pay attention to the batteries
you might get one of these improved 2 coils shake flashlights
with 3 LEDs, that don?t need any batteries at all :

Or you take one of these with hand cranking power input, also working very well:
