I know this is a widespread failure mode on street lights or exterior LED lighting, and I’ve been seeing more and more purple LED street lights out in the wild, even tho I haven’t really seen them in 2021 in our area. I haven’t seen household LED bulbs turn purple, are they affected too?

Have you’ve seen any purple LED screw-in bulb? I believe I saw the first purple street light in 2024.

I thought the same thing! Apparently, some household lamps are doing it, I have seen a few picture floating around LG of exactly this. Never seen it in person, but I will take a picture when I do.

Here is @Maxim's cool picture of some Cree bulbs that turned purple:

Yes they indeed are!😀, I have a 2 watt filament lamp at the top of my stairs that runs 24/7, it’s slightly noticeable by eye, but in the photo I have turned the colour saturation up so you can clearly see it👍
