They probably are fairly crude. I know they flicker, for example if
I
use my cordless drill, the chuck appears to spin the wrong way under
the
LED lighting.
I remember seeing that with a washing machine (under fluorescent
lights). As the tub was slowing down, the row of holes around the tub
would appear to reverse direction. Same thing with (spoked) wagon
wheels
in movies.

You can also observe such things using a smartphone that has a high FPS
rate for recodring movie.
I can see the labs lights flicker when I film at 240FPS standard 60
and everything seems fine.

Everybody seems to constantly cut corners. Lights should just be on, no
flicker at all. ****ing annoying if you have decent eyesight, I can see
the flicker from almost everyone's LED tail lights.


This is sounding more and more like our "engineer friend" who needs
to do his own tire repairs and alignments and clutch repairs.

Don't know who you're referring to, but what's wrong with striving for
perfection?

It increases costs for everyone who isnt a freak.

There's perfection and there's perfection. You for example like LEDs you can control the colour of, nothing wrong with that. But OCD folk take things too far, like washing their car every day because of two specks of dust.
