Key phrase and simple alternatives
Start with the basic phrase used when a light will not come on: a luz não acende. This is the most natural way Brazilians describe a light that is not turning on. It is short, direct, and used in homes, apartments, and workplaces.
Other short alternatives you will hear include a lâmpada não acende and o interruptor não funciona. Use a lâmpada não acende when you suspect the bulb itself is the problem. Use o interruptor não funciona when the switch might be broken.
Literal breakdown of the key phrase
Understanding the grammar helps you remember and adapt the phrase. In a luz não acende:
luz is a feminine noun so we use the feminine article a.
não is the negative particle, used before verbs.
acende is the third-person singular present form of acender, which means to light or to turn on.
Common variations and when to use them
Here are natural variations you will hear and how to choose the right one:
A lâmpada queimou — Use this when the bulb burned out. Queimar in this context means to blow out (a bulb).
O fusível queimou — Use this when a fuse blew. This phrase is more common in older houses with fuses.
Deu um curto — Colloquial for a short circuit. Use with care; it suggests an electrical fault rather than a simple bulb problem.
Não tem energia — Use this when there is a wider power outage affecting more than one light or appliance.
Useful verbs and nouns for electrical problems
Learn a small set of verbs and nouns to expand your ability to describe problems.
Verbs: acender (to turn on, to light), apagar (to turn off, to go out), queimar (to burn out), funcionar (to work), piscar (to flicker).
Nouns: a luz (the light), a lâmpada (the lightbulb), o interruptor (the switch), o disjuntor (the circuit breaker), o fusível (the fuse), a tomada (the outlet).
Example sentences with explanations

Ask someone to check the breaker when you suspect a short circuit and the lights are out.
Polite ways to ask for help
When asking a roommate, neighbor, or building manager for help, be polite and specific. Use conditional and modal constructions to soften your request.
