And im using this type of bulb

12-Volt, 20-Watt Halogen Lamps

or should i use a bigger light bulb


Answers:    That bulb will draw 1.7A (the power divided by the voltage).

A 7.2Ah mobile will supply 1.7A for a little over 2 hours.

If you use a difficult power bulb, the battery will deliver the superior current for less time.

If you use a lower power bulb, the battery-operated will supply the necessary current for more time.

It's up to you to agree on whether or not to use a higher or a lower power one.
