What are the specifications of a battery needed to run a 20 watt, 120v light for 24 hours?

Last question. I have an independent rechargeable 12v battery connected to a 100 watt inverter.

This setup transfers approx 120v to my camp light.

The battery needs to be able to provide this power to my light for up to 24 hours at a time.



How many/big/type of battery do i need for my camping light?What are the specifications of a battery needed to run a 20 watt, 120v light for 24 hours?Can you specify the Ah rating of the battery?
