Hi OZBers,
Does anyone know the name of these downlights are and how to replace them? A few of these lights in my house died, hence bought a few Philips LED downlights from the Woolies Deal last week but didn't fit. :(
These lights don't seem like LED either.
Could any expert help?
Your help is greatly appreciated.
Thank you.
Thanks SpottyMoose. I'm not sure how to remove the aluminium casing? I also see there's a switching transformer on the other side of the the cable.
Rotate the metal ring in the second picture counter clockwise and it should pop off. Use the three tabs on the ring to grip it.
Thanks Harshad. That I've done. I mean I don't know how to pop out the lamp from the aluminium casing. I've tried rotating the glass plate but no luck. Kindly see image 3 and 4. Thank you.
If there's a transformer then they'll be 12V Dichroic.
Thanks again. New images (3 and 4) have been uploaded for your reference.
@sol3x: That huge heatsink makes it look like LED. There's probably a driver attached to the other end of that black cable… although looking at the thickness of the cable, the driver could be integrated into the bulb. What's on the other end of it?
The second photo looks like it's showing a yellow COB LED, the third photo looks like it shows a TIR reflector in the centre.
Maybe. :)
What colour were the lights originally? If you held your hand in front of the light when it was running, did it feel really hot?
@eug:
Thanks eug. Kindly see image 5.
Found the driver and it seems it's a 12V light. The colour of the light is warm/yellow colour like the old halogen downlights. I do feel a bit hot when I put my palm in front of the light. I'm not sure how to remove the heat sink to replace the light. :(
Yeah, LED not dichroic…. sorry.
I always thought LED lights were supposed to last forever (or a long long time).
Maybe that's why you're having a hard time removing the bulb, perhaps it wasn't designed to be replaced.
Above my pay grade now… 😀
@sol3x: Ahh, it definitely is an LED. What's on the other end of the thinner black cable on the driver? Is it a power plug?
You can't easily replace the LED. It's more likely the driver that died though; they tend to fail a lot more frequently than the LED. Unfortunately there's no real standard for LED drivers. That's a 660mA driver with a max voltage of 17V. You can replace it with a more reliable one like something from Meanwell, but it'll cost quite a bit. It's cheaper to just replace the whole downlight. Does it have to match your other downlights? If it doesn't, you can get a round downlight from Bunnings for $10-20, or a square one from a lighting shop, e.g. this one which could be the same as yours, but in white. edit: silver costs way more. Better shop around!
If there's a power plug on the end of that cable, you can just swap it yourself. If it's hardwired, maybe get an electrician instead…
@eug: Thanks very much eug. Kindly see image 6 for your reference. No power plug could be seen on the other side of the driver.
Those downlight kits you posted, it means I also need to get a new driver?
@sol3x: Based on image 6, it looks like the installer has chopped off the power plug and connected the wires directly so they can skimp on connecting a power socket on the other end of the wire.
@sol3x: Ahh, older installations are often wired directly like that. The downlight kits I posted come with the driver included. They all do. The ones I linked to was just from a quick search; I don't know if the dimensions/colour/design are the same as yours, so do your own searching too. :)
Nowadays they all usually come with power plugs on the end, which makes it quicker and easier to pop on a 413 socket in the ceiling (and charge you for it) than it is to hardwire each light.
If you're getting a sparky in, you should just ask them to install a 413QC socket so you can easily change it yourself next time.
@eug:
Thanks very much eug. I may buy the lamp kits and do it all myself. Frustrated as there are 5 out of 40 lights died already. That's like 12% fail rate. So crappy.
Go to a lighting shop and ask the experts
Thanks barbarella, thsts one option too :)
LEDs in downlights might not be replaceable, may need to replace the whole thing. A few of my downlights stopped working and it's because of the drivers (transformer). It was cheaper to buy a new exact same downlight with driver, than just the driver itself. How old is it?
Thanks wkapri. The lights are less than a year old. So frustrated that they died so early.
Any warranty on them?
Not sure. The previous owner of the house installed them during the renovation. :(
Hard to tell until you take the actual bulb out.
It's going to be either 12V Dichroic or 240V GU10.
