HELP! Downlight not working

[Richieduliban]

Hello, I cannot get a replacement downlight working for some reason.

I briefly connected it without a switch just for testing. Could it have damaged it by bypassing the switch? Or does this have no bad consequences?

Well - no consequences by not having a switch, but do you mean it then worked or still didn't work?

What voltage bulb is it ,may need a transformer.

 

[Richieduliban]

It has never worked. The downlight is Enlight DLM982X. It says max 50W ans 220-240V on the box.

I tried first using 5W dimmable LED, and it says 220-240V on the box.

Then I tried with a non-dimmable 3.1W. Doesn’t say the voltage and still no luck.

Power was getting to the downlight. I then tried with a switch, and traced power and the wiring seemed fine but still no lights.

As usual... how do you know power was getting to the downlight. What means of testing did you use?

 

[Richieduliban]

Power tracer pen. When switch was off no beep on the switched live cable. When I turned on switch it beeped.

When I installed it with no switch it beeped too.

You probably lost the neutral. You need a two probe voltage tester or multimeter. To measure voltage line to neutral.

I'll just get a sparky in. But sounds like I did not damage it by first not having a switch?

 

[terryplumb]

How / what did you connect it to without a switch ?

 

[Richieduliban]

The live cable that usually goes to the switch was connected to the light directly instead of the switched live.

 

[terryplumb]

That's no difference really ,and if you had the circuit switched off at an MCB for instance ,when you turned it on you did use a switch !!!

 

[Richieduliban]

Yes, so no idea why it’s not working, very strange. Time to get sparky in to check if they’re faulty. Thanks for your help.

 

[terryplumb]

As said earlier ,could be a disconnected neutral.

You were right! Many thanks
