WE know this is mostly an inferior solution.
BUT for the uninformed, a huge number of LEDs sounds very good, AND they are still cheaper than an LS AND you do not have to worry about the beam since the 5mm LEDs provide their own optix, it is much easier to do a light like this.
AND ... SF did it as well, think KL2 ... /ubbthreads/images/graemlins/grin.gif
As for the power source ... small cells for small lights, big cells for big lights ... but this combo with small cells in a big light is funny.
