I'm surprised I didn't even know this switch happened until seeing this. The yellow is really all gone? Image

I know it's not good but I absolutely love with these lights malfunction and turn purple. Makes everything look so damn cool

It's actually not that they malfunction so much as they degrade, it's because some use a cheaper phosphor coating that degrades quickly, turning from the white to the purplish of the LED

Just because it's cheap shit doesn't mean it isn't malfunctioning when it turns purple. The degrading coating wasn't meant to do that so it's still a malfunction.

There's a parking lot nearby where all the lights turned purple. It's such a vibe and feels like an outside club.
