Έσβησε ο φωτισμός ασφαλείας, με αποτέλεσμα να περιμένουμε.

Here Έσβησε means went out, switched off, or stopped working.

It comes from the verb σβήνω = to extinguish / to switch off / to go out.

In this sentence, it is the aorist form, so it refers to a completed event in the past:

• σβήνω = I switch off / I go out
• έσβησε = it switched off / it went out

Because the subject is ο φωτισμός ασφαλείας, the meaning is:

• the emergency lighting went out

Greek often uses the active form of σβήνω both transitively and intransitively.

So:

• Έσβησα το φως = I switched off the light
• Έσβησε το φως = The light went out

This is very normal Greek. Even though English uses an intransitive phrase like went out, Greek can still use the active verb form.

Greek word order is much more flexible than English word order.

So both of these are possible:

• Έσβησε ο φωτισμός ασφαλείας
• Ο φωτισμός ασφαλείας έσβησε

The version with the verb first is very natural in narration, especially when introducing an event:

• Έσβησε... = The lighting went out...

English usually requires subject + verb, but Greek does not.

Literally, it means the lighting of safety.

More natural English translations would be:

• the emergency lighting
• the safety lighting

Here:

• ο φωτισμός = the lighting
• ασφαλείας = of safety / safety-related

So the whole phrase is a noun followed by another noun in the genitive, which is a very common Greek pattern.

Ασφαλείας is the genitive singular of ασφάλεια = safety.

Greek often uses the genitive to show a relationship similar to English of:

• ζώνη ασφαλείας = seat belt (literally belt of safety)
• μέτρα ασφαλείας = safety measures
• φωτισμός ασφαλείας = emergency/safety lighting

So ασφαλείας is not an adjective here. It is a noun in the genitive case.

Με αποτέλεσμα means with the result that, resulting in, or as a result.

It introduces the consequence of the first event:

• Έσβησε ο φωτισμός ασφαλείας = the emergency lighting went out
• με αποτέλεσμα να περιμένουμε = resulting in us having to wait

So the structure shows cause → result.

After με αποτέλεσμα, Greek often uses a να-clause to express the result.

So:

• με αποτέλεσμα να περιμένουμε

This is a common pattern. You can think of it as:

• with the result that we wait / had to wait

The particle να introduces a subordinate clause, usually with a subjunctive form.

This is a very common question.

In να-clauses, Greek does not simply choose a tense the same way English does. Instead, it often uses:

• present subjunctive for an action seen as ongoing, repeated, or in progress
• aorist subjunctive for a single complete action

Here περιμένουμε is the present subjunctive after να, and it suggests an ongoing action:

• να περιμένουμε = to be waiting / to have to wait

That fits the meaning well, because waiting is usually something durational, not a single instant.

So even though the main verb is past, the dependent clause can still use να + present.

Because the ending -ουμε shows 1st person plural:

• περιμένω = I wait
• περιμένεις = you wait
• περιμένει = he/she/it waits
• περιμένουμε = we wait

Greek often leaves out subject pronouns when the verb ending already makes the subject clear.

So να περιμένουμε already means:

• for us to wait
• that we wait
• in natural English here, so we had to wait

Because Greek is a pro-drop language: the subject pronoun is usually omitted when it is clear from the verb ending.

So:

• περιμένουμε already means we wait

You would add εμείς only for emphasis or contrast:

• να περιμένουμε εμείς = for us to wait / for us, specifically, to wait

Without emphasis, leaving the pronoun out is the normal choice.

Yes, it is somewhat more formal or written in tone.

Compare:

• Έσβησε ο φωτισμός ασφαλείας, με αποτέλεσμα να περιμένουμε. = more formal, structured, explanatory
• Έσβησε ο φωτισμός ασφαλείας, οπότε περιμέναμε. = more straightforward, conversational
• Έσβησε ο φωτισμός ασφαλείας και περιμέναμε. = simpler and more neutral

So με αποτέλεσμα is often used in written Greek or in speech that sounds more careful or formal.

Yes. A common alternative is ώστε.

For example:

• Έσβησε ο φωτισμός ασφαλείας, ώστε να περιμένουμε.

But ώστε can sometimes sound a little different depending on context, and με αποτέλεσμα very clearly highlights the result.

Other possible ways to express the idea include:

• οπότε περιμέναμε
• κι έτσι περιμέναμε
• με συνέπεια να περιμένουμε

Each option has a slightly different tone, but με αποτέλεσμα is very natural here.

Yes, the comma helps separate the main event from its result:

• Έσβησε ο φωτισμός ασφαλείας,
• με αποτέλεσμα να περιμένουμε.

It makes the structure easier to read and reflects the pause you would naturally hear in speech.

Without the comma, the sentence would be harder to process, especially in writing.

Sometimes, depending on context, but emergency lighting is usually the most natural translation.

Why? Because φωτισμός ασφαλείας often refers to lighting used for safety in emergencies, such as when normal power fails.

So in many contexts:

• emergency lighting is best
• safety lighting is possible
• security lighting is less likely unless the context is specifically about protection against intruders or surveillance

Context decides the best English wording.
