What it means
The brief stretch when the electricity is actually on. A sarcastic coinage that inverts apagón, 'blackout': if the power is off most of the day, the notable event is the light, not the dark.
Used as a unit of planning — cooking, charging phones and pumping water all get scheduled around it.
Examples with translations
Aprovecha el alumbrón y pon el arroz.
Make the most of the power being on and get the rice going.
Aquí ya no hay apagones, hay alumbrones.
We don't have blackouts here any more, we have brief bursts of electricity.
Note: The joke in its standard form, current across the island through the energy crisis of the 2020s.
Where it comes from
Built on alumbrar, 'to light', with the augmentative -ón lifted straight from apagón. The coinage is old enough to have appeared during the blackouts of the 1990s Special Period but became genuinely ubiquitous after 2021.
First attested: 1990s, revived from 2021
