After sitting idle for the Winter, 3 of the amber LED bulbs in the front landscape lights have turned a pinkish color. Very surprising to see this happen when the lights were not in use.

For DEL's the reason for your lights to turn pink is from phosphor degradation where it can degrade unevenly and some of the blue light will pass through giving you a slight pinkish haze, so the phosphor gives the DEL a approximation of what a blackbody at said 2200k color temperature would look like but as phosphors go through trauma or harsh conditions the phosphor can degrade which could shift the 2200k approximated light into pinkish hues below the blackbody curve (-DUV tint) or above the blackbody curve (+DUV) green tint, in some cases depending the on phosphor chemical makeup, that's why some DEL's look green and some DEL's rosy.
good video bro not good that del bulbs are turning pink i enjoyed the video
Possibly phosphor degradation from the cold for some reason, maybe defective coating process. You could just remove the bulbs before you shut down the lights for the winter and store them indoors until next season?
I’m not surprised that they failed. It’s LED after all!
These would look good in a red white and blue pattern for this summer. This is 250th anniversary for USA!
They look like 12 volt yard lights
most decent led light bulbs are actually engineered to produce uv, the uv hits the phosphor which converts to visible light of required spectrum. it's not just a filter. uv producing lights do make a blue glow but it is primarily producing the invisible uv.
I honestly prefer the purple of busted street lights over the awful cold 6500k “white” light they are supposed to make.
You can actually get true, amber, l e d's without the phosphor no look more like a low pressure sodium
you should take out the bulbs from the fixture and store them inside for winter
There are reasons to hate DELs.
