What Happened to the 100000 Hour LED Bulbs? | Hacker News
In my experience, Philips lightbulbs are one of the few brands that don't have this flaw because they take care of converting AC to a stable DC voltage internally. In fact they are advertised as such: https://www.amazon.com/dp/B07CFRCGKC "COMFORTABLE LIGHT: Our products meet strict test criteria including flicker, strobe, glare and color rendition to ensure they meet EyeComfort requirements"

LED flicker could prove harmful or fatal if you work with anything that rotates or reciprocates.
The rotating / reciprocating mass may appear stationary at some RPM.
Just a reminder to only ever use incandescent or halogen lights around machinery you can touch while in operation: drills, lathes, mills, slotting machines, etc.
