It's actually not something covert. It's a manufacturing quality problem wherein components fail and the units have to be replaced with better quality devices. However this purple light problem is real and is widespread in some communities.
If it hurts, the lamps may be putting out a lot of ultraviolet. Here's a test: have something that is fluorescent orange. If it appears bright orange at night under the lamp, that's a sure sign this is an LED lamp whose internal phosphor has failed and it lets dangerous UV from the diodes out. (UV causes fluorescent materials to glow and actually emit light.)
A white light LED works like this: the LED actually puts out ultraviolet at the core. The LED converts that to white light by having a phosphor coating around the emitter to do that, they operate just like a standard fluorescent tube light. In the street lights with a manufacturing defect, the coating degrades and lets purple and UV out. And that damages eyes.
This may be topnotch Chinese LED quality here, where they are shoddy just to save a penny.
If the light hurts your eyes at night, blueblocker glasses can stop the UV. They will look clear for ordinary light but they block UV wavelengths. Might be useful for a cop on night patrol.
I am a reef keeping nerd, and know the capabilities of UV especially from LED format. Trust me bruh.....those little diodes from ALL the way 10" feet above our heads is NOT enough UV to do shit. For instance the UV in a reef tank gets dilluted by the time it hits the sand bed in most 14" aquariums. The purple especially. Thbere is t-5 bulbs tho.....these flourescent bulbs and metal halides, used to put out mega fuck tons of UV. Especially the halides. Which WERE the old street lights lol. :D:D:D:D
