LED Downlight faulty - Strobe effect

[homemove]

Hi guys,

I have five bathroom downlights. Four are working perfect, but one is faulty. After turning the light switch on, this faulty one is flashing/strobing really fast. It's like being in a nightclub.

I've already replaced the led bulbs, but it still does the same. I'm not very knowledgeable, but I think it might be a faulty transformer or something.

Below, I've attached pictures of what looks like a blue transformer, but I don't know what the other white part is.

Could anyone please kindly post a few links from ebay/amazon to help me find a replacement for these parts as I don't know what to order and want to make sure I get the right parts.

Thank you.

The blue box converts mains voltage to 12v for the old type (halogen) lights.
If you read the box, it says 20-60VA. So you will have problems unless your LED lamps if more than 20VA (= watts in this case). So the blue box and the LED lamp are probably not compatible
So you need to change the blue box for what is known as a LED driver suitable for your lamp.

The question then is, how come the other 4 work OK. Maybe they have a different make of blue box? or maybe there are more than one lamp connected to the box, making the load big enough to avoid the problem.

What's the situation?

I've double-checked another one and it's exactly the same as the first downlight transformer:-

Swap a lamp that doesn't flash for the one that does.

 

[Taylortwocities]

I thought that he had already done that?

I've already replaced the led bulbs, but it still does the same.

 

[stillp]

Sounded to me that he'd fitted new ones.

 

[homemove]

Already replaced the led bulbs.

So shall I now try replacing the blue transformer?

 

[Taylortwocities]

Replacing it with what?

 

[homemove]

Replacing it with what?

Replacing it with another like-for-like transformer?

 

[Taylortwocities]

NO !!!!!
Did you not read my post????????

[homemove]

Ahh sorry. So could you kindly show me what it looks like on ebay or amazon?

 

[Taylortwocities]

I never use or recommend either of those places!
Also it needs to be compatible with the Led bulb.
The manufacturer usually has a list of suitable drivers on their web site.

You haven't even said what the voltage is, but I'll assume 12v.

If you want to take a chance, Just Google "12v LED driver".

Sorry, but i'm not very familiar with downlights, so wasn't sure what information you would require.

Do I need to check the led bulb to find out the voltage?

This is designed for LED lamps and will work: http://www.screwfix.com/p/halolite-led-constant-voltage-driver-1-16w/85503

This is the equivalent of what you have, and is designed for halogen lamps. Anyone's guess as to whether it works with your LED lamp or not: http://www.screwfix.com/p/halolite-low-voltage-electronic-transformer-20-60va/48058

Right thank you for that link flameport.

I'm surprised that the other led bulbs are working with the old halogen transformers. Will I need to change them all or just the faulty transformer?
