Regarding failure:
White LEDs consist of a blue LED chip with a phosphor to fill in the rest of the spectrum. It is possible for the phosphor to degrade over time, changing the color of the light somewhat. Some white LED backlight strips for LCD monitors/TVs have shown a failure mode in which some individual LEDs become dark blue. This has been discussed online (here or on YouTube, I don't recall), but I have not seen an explanation of the failure mechanism.
It's orange like the old high pressure sodium(?) lighting that it replaced...Some of them HAVE FADED to warm white and bluish white but most that have failed failed blue like in the pictures subsequently posted.
