Que tipo de + noun
Use “Que tipo de” to ask about the kind or category of something; it works like “what kind of” in English.
funcionar (present indicative)
The verb “funcionar” means “to work/operate”. In the third‑person singular present it is “funciona”.
melhor as adverb
When “melhor” follows a verb it acts as an adverb meaning “better” or “best”. No “mais” is needed.
question mark placement
In Portuguese the question mark is placed only at the end of the sentence, unlike Spanish which uses opening and closing marks.

Cultural Tip
In Brazil, “luz” can refer both to the source (e.g., LED, fluorescente) and to the general concept of lighting. When speaking with older generations, you might hear “lâmpada” used more often for a specific bulb. Also, avoid the redundant “mais melhor” – Portuguese already uses “melhor” as the superlative.
