I am in possession of two 12 volt 10 amp batteries. When connected in sequence they produce 24 volts and 10 amps which are a total of 240 watts. With this I am trying to power a 240 watt t5 halogen bulb rated at 30 volts and 8 amps. If i power the halogen bulb with 24 volts and 10 amps will it work as effectively as if use 30 volts and 8 amps?
Do different amounts of volts and amps matter if the end wattage is the same?

I was taught in class that amps and volt could be related to a car, amps being like the size of the car, and volt being how fast the car is moving. Since amps multiplied by volt's give you the watts should they balance out?

Volts, amps, and watts may or may not be related. A battery has a rated voltage, but when you say 10 amps I wonder what you are talking about. When you hook something to a battery it draws as much current as it wants and a battery is only rated for the time it can supply a certain current. A tungsten lamp might draw a lot more than normal current when it is cold. I have no information about halogen lamps. But in general, a lamp run at less than its rated voltage is a poor source of light.
Here is a detailed description of how a halogen lamp works when the voltage is reduced:

Ok thanks, I will follow the link . Just to add in thou i have lithium ion batteries with circuit protection so that the battery discharges no more than 12 volts and 10 amps to prevent over-heating.I was just wondering that if wattage is kind of like the measurement of total power, that amps and volts balance each other out.
