Anyone recognise this LED downlight?

Jonny08 · 25 Oct 2020

Hi all,

I live in a new build that is now 6 years old. One of my downlights has stopped working in the kitchen. I've been searching and searching to see if I can find the exact same unit but I can't find anything.

Any ideas of the make/model of this please? If not, is there an alternative with this connection?

Thanks.

Wheres the driver, the label on the driver also often indicates the manufacturer.
Was there not a label on the Bezel or wrapped round the Driver lead.
I would plug the head into another working fitting, if it works then you wont need a new head and likely just the driver
Turn the lights off to do this as best not to run the driver with no head plugged in

Thanks.

I've just done that - the head works on another working fitting, so it must be the driver. Using an electrical tester, there is live showing on the wire between the driver and the head. I can only assume the driver has gone faulty and the power it's supplying to the head is not correct.

Picture below shows the driver, I can't find the exact model to replace it with online, I assume this would be fine?

No, that is a constant voltage device, totally unsuitable and would destroy the LED instantly.

If the lights are just on/off (no dimmer), then this: https://cpc.farnell.com/sunpower/pcc35012/led-driver-c-c-350ma-12w/dp/PW03876
If they are on a dimmer, then this: https://cpc.farnell.com/sunpower/pcc35009td/led-driver-c-c-triac-dimming-350ma/dp/PW03878

You will need to remove the connector on the LED and connect the two wires directly to the driver terminals, and it's essential that they are connected + / - correctly. Incorrect connections will cause damage.

Unless you are desparate to keep those lights, I would be looking to replace the whole lot with something else, such as GU10 lamps.
Individual CC drivers and LED elements were only a thing for a very short time, and it will become increasingly difficult and expensive to find replacements.

Perfect, have gone for that - thanks for the advice, and education regarding Constant Voltage and Constant Current drivers.

Thanks for the help guys, really appreciated.

If you snip the output wires off the old driver and connect them into the new driver then you can keep the small plug/socket arrangement for the downlight, as Flameport says, POLARITY is important, but not always visibly clear.

Googling the part number suggests the lights may have come from Build Base, page 115

Hello again - there is an issue with my CPC order, looks like they are out of stock. Is this CC Driver compatible please? Or is the Wattage output slightly too high? (I need a dimmable one) - https://www.amazon.co.uk/gp/product/B076QHQ5HJ/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1

I would not risk it as it may blow the head, constant current drivers self adjust to limit to, in your case 350ma, by adjusting the voltage in relation to the wattage, in your case 6watt, looking at your old one, its maxed out at 14 volt so your heads likely designed to run at less than 14 volt.
The amazon one does minimum 18v to 35 v max, so looks like it may over volt your head causing irrepairable damage.
Though i do believe for a 6w head at 350ma it would be 6 divided by 0.350 = 17.14 making the original one underrated, or the head is really less than 5watt

You could contact the supplier. Maybe they sell a replacement...
