Help! Which LED driver do I need

jumpjamesjump · Oct 10, 2022

Hey all.

Have a client who’s LED downlights keep breaking after 6 months or so. I didn’t put them in originally.

I looked the details on the lights and the transformers and they don’t seem to match. But I can’t find anything to match the light as the input current is 300ma and voltage is 85-265V AC. Could anyone help me out finding the right match. Picture of old transformer and light are attached.

I was wondering if they even need a transformer and could go straight into 230v but wouldn’t dare since not even close to sure.

Thank you very much

Those are mains voltage LEDs and have built in drivers.

I thought this too.
I found the LED lights online though and they are pictured with transformers even though it states the same input voltage as the one in the picture.

Just feel worried about taking out the transformers when I believe they come with the original order

They are constant current LED fittings that need a constant current driver to match (ie 300mA) The voltage stated is the input voltage range to the driver to ensure a 300mA output, not the voltage to the actual light fitting.

Are the drivers overheating in insulation? I would normally overpower the driver (say 15w for a 12w lamp!).
