That explains why most newer LED lamps flash at 120 Hz, slomo mode fails on cameras, and one gets wierd strobing effects with fast moving stuff...

I wish they'd just use electrolytic caps and make the light output actually constant...

Yes. I hate it when LED light output isn't continuous or visibly flickery, especially when it's from LED lights that are on (or are visible from) moving objects -- such as LED taillights on automobiles or in-road lane lights. All the eye movement (or object movement) makes the flicker even more flagrant :(

I remember extremely flickery lane lights on the leftmost lane markers on the infamous SR 110, on the northbound direction in the tunnels (the ones right before the left-exit to I-5 north).
