Power supply for LEDs?

I usually order power supplies on Aliexpress or Amazon. Lots to choose from in terms of voltage and amperage and they're usually pretty cheap.

If the lights are wired in series, then the failure of one LED light could have caused them all to stop working.

I second this, it will take time, but Aliexpress has several LED Drivers as they call them. I was exploring recently as I was looking for LED Kitchen undermount strip lights. I was happing to find really slim ones that infact are direct 120v power supply capable without a need for driver. I got them delivered, will be installing them soon and time will tell if they hold up, but were pretty cheap. All other local store solutions here involved using a laptop charger sized power adaptor to hardwire them to 120v.

If time is not a factor, order from Aliexpress. It can take anywhere from 2 weeks to 3 months.
If time is a factor, order from Amazon (shipped from Amazon warehouse).

Another thing you want to check is the power consumption.
When I did a major reno 5 years ago, the contractor put in an AC adapter that was slightly undersized. I didn't know. It burnt out after a few months. I replaced it with the same output one. Then it burnt out again after a few months. Then I checked the output and I realized it should have a higher output. So I replaced it with a higher output one and it never burnt out.
