Nitpick: "are actually purple" makes it sound like they came out of the factory purple, but they're actually changing from white to purple over time as the phosphor coating fails.

Just to be clear, these are about 1-3 years old. So yes they probably weren't purple on the day they were installed, but this is a defect and not normal aging. https://www.reddit.com/r/todayilearned/comments/136nz3b/til_...
They'll be near-UV LEDs with a phosphor to produce white, high efficiency, low cost, but garbage long term.
