Portuguese generally uses a definite article before a specific noun. You say acender a luz (“turn on the light”) rather than acender luz.

Yes. In Brazilian Portuguese, ligar a luz and acender a luz are both common and interchangeable when talking about turning on a light.

Why is eu optional in Eu posso acender a luz agora?

• Agora posso acender a luz.
• Posso acender a luz agora.
• Eu posso agora acender a luz.

What’s the difference between posso and consigo here?

Posso (from poder) asks for permission or indicates possibility (“May I?”).
Consigo (from conseguir) expresses ability (“Am I able to?”).
Since you’re asking “May I turn on the light now?”, posso is the right choice.

Is it correct to write ascender a luz with sc?

Do I need any prepositions with acender?

No. Acender is a transitive verb, so it directly takes its object: acender a luz. You don’t add prepositions like em or em/na here.
