Alternatively, 3 x 18650s in a carrier would give you 11.1 volts, but only half the capacity so depending on what runtimes you require you could go for a much lighter set up. (5 oz) 6 x 18650 would give you similar capacity to the lead acid (6 x 18650 = 10 oz).
4 x 18650s would give you 14.4 volts and a lot more current resulting in a lot more light at the expense of bulb life.
Of course...if you used LEDs as well.....
