I was reading throughout the forum in the dislike concerning flashlights which use a 3cell aaa carrier. What exactly are the disadvantages of this setup. Likewise what advantages are there from this power setup?

Another, less important reason: Batteries are sold in even numbers and a 3-cell light (or any battery operated gadget) leaves an extra battery left over.

Cheap 3AAA lights don't usually have even that. They direct-drive the LEDs, counting on the internal resistance of alkailnes or lower voltage of rechargeables to avoid overdriving the LEDs so hard that they burn out in less than five minutes.- cheap 3AAA flashlights usually have no driver inside, only a resistor to avoid overdrive
But even then, you have to face the fact that AAA cells, not to put too fine a point on it, suck. They have nowhere near the grunt to drive high-flux LEDs, or arrays of more than two or three non-overdriven 5mm ones.
