This one bit me recently when I bought a package of budget light fixtures (in Canada, from amazon.ca) and then my licensed electrician informed me that he wouldn't be able to install them as they didn't have a CSA or UL mark. (edit: originally I had mis-recalled and said CE here)
To their credit, Amazon did allow me to return them without penalty, and now my review there warns other consumers that those are only for DIY use and even then you are risking your home's insurance coverage.

Actually make sure with a incognito window that this review is actually visible. I've noticed that some reviews of mine have been "shadow-banned" and while it looks like they're still there when I'm logged in, once I try in a incognito window the review doesn't show up publicly anymore. My reviews were just basically facts about the products themselves, and received no word from Amazon about breaking any rules.
I posted a legitimate negative review once and it got immediately memory-holed. I laugh every time they send an email begging for reviews. I'm not wasting my time if you're going to hide the truth.
I've noticed this too. Vine Gold Amazon program member, but sometimes my reviews are rejected or shadow banned for no discernible reason. I think there may be some corruption in the review moderation process (as well as in the commingling process, which I've also had problems with).

The CE mark signifies compliance with European Union standards and regulations. Why would you expect Amazon Canada to care about that?
IIUC Chinese manufacturers often put the "CE" mark on things that haven't been certified, and rationalize it as the mark meaning "China Export"
I have never heard of a case of a homeowner's insurance claim being denied based on imrpoper DIY work. One of the main points of insurance is to protect you against your own negligence.
Still, I would make the same decision and steer clear of such lighting fixtures!
CE conformity is a self-declaration by the manufacturer, so essentially the honor system, not an actual certification program like TüV. Items without a CE mark cannot legally be imported or sold in the EU, but there is little enforcement.
Ah yes, I'd looked this up before but then forgotten it. My original comment would be better stated as "Chinese manufacturers often put the 'CE' mark on things they haven't designed to conform to the guidelines, and have no intention of standing behind the liability for ..."
The replacement ones that the electrician selected were only slightly more expensive and I was able to clean up the look of them with 3d printed shrouds:
I've really got to get back into 3D printing. I was building a Voron back when it would have been like serial number 20. Got it to the point where I was printing its own parts (using stub parts made of plywood and whatnot). Life happened, I disassembled it to move, and I've still got the frame sitting around plastic-wrapped for the past ten years.
I wasn't even thinking LED fixtures. For LED fixtures with built in power electronics, I would definitely want the product to be NRTL recognized.
I was late to the 3d printing game and in part that was just not wanting it to become a junk factory of disposable toys and fidgets. I've definitely printed a bit of that kind of thing but overall I've been pleased with the number of small household fixups that it's been possible to do using it.
Just last night for example my microwave oven stopped registering that the door was closed, and within a few tries I was able to print a replacement for the latch bracket that had broken off. At any previous time in my life that would have been either a whole new door or replacing the entire unit.
For sure, I've got a list of "household fixups" to print when I finally do get around to rebuilding the thing.
Just a note of caution about the microwave though. I don't know what bracket broke off your microwave, but usually the door switch is a safety mechanism to make sure the door cannot be open while the magnetron is on.. Make sure a new 3D printed bracket isn't able to break off and cause the safety switch to remain on!
Oh yeah, I'm well aware. The PLA bracket is non-structural and only supports the original latch piece.
That said, I was alarmed to see online lots of people who were also replacing the latch itself with printed parts. That sketches me out a lot more, though I guess it could be fine with PETG or ABS.
