Spanish Phrase
Sí, todas las luces están apagadas.
Meaning
The sentence means “Yes, all the lights are off.” It confirms that every light in the referenced space is not turned on. The verb "estar" is used because the state of the lights (off) is considered temporary, and the participle "apagadas" agrees with the feminine plural noun "luces".
When to use
Use this phrase when someone asks whether the lights are on or off, for example after a question like "¿Todas las luces están apagadas?" or when you want to describe a dark room or a house that has been switched off to save electricity.

Cultural Tip
In many Spanish‑speaking countries it is common etiquette to turn off lights when leaving a room to save electricity. The verb "apagar" is also used for electronic devices, so you might hear "el televisor está apagado" (the TV is off). In some regions, especially in Latin America, "luces" can also refer to streetlights, so the same sentence could describe a quiet, unlit street at night.
