The correct answer is 12 light bulbs. Electric eels (Electrophorus electricus) can generate electrical discharges of up to 860 volts. While the exact number of light bulbs depends on bulb wattage, educational materials commonly cite the ability to power approximately 10-12 standard light bulbs briefly. Their specialized electrical organs (composed of electrocytes) store and release this charge, used for hunting, navigation, and defense.
