Ten 60 W bulbs would need 600 W, and a 12 v battery would therefore have to supply 50 amps. A 50 amp-hour car battery would theoretically supply that for one hour, but in practice the capacity is reduced when the load current is high. So a car-battery would do the job for about half an hour. To last for eight hours overnight would need 8-10 car batteries connected in parallel.

To run ten 60-watt bulbs, you would need a battery capacity of at least 600 watt-hours (10 bulbs x 60 watts = 600 watts). Keep in mind that for practical use, it's recommended to oversize the battery to account for inefficiencies and ensure longer run times.
