8 x 1.5 volts = 12V
8 x 1.2 volts = 9.6V

As a result I would expect the Lithium batteries to result in brighter LED's.

The only concern would be the LED's ability to dissipate the extra current. They may be be brighter only for a short period of time.

I=E/R is the answer to your question. The higher the voltage the greater your current, the brighter your LED.
