Flicker-free and T8 LED Tube Light Questions

So I’m doing research on LEDs and why some leds flicker and strobe. I see this is truly an issue as a lot of people deal with this problem. For the record, I’m talking about (visible) flickering/strobing. I know all LEDs flicker which we mostly can’t see, but causes headaches, fatigue, etc. But I’m dealing with visible flickering that driving me nuts. 

-Why does this happen with certain LEDs? 

-Will your “waveform flicker free” tube lights stop the visible flicker I’m having?

-And I’m very curious about what sets your lights apart from competitors with this “flicker-free technology”. Do you use a super high-quality driver in the bulb? 

Generally speaking, the flicker rate of often defined by the capability of the connected power supply. If the power supply is not adequately treating the power being afforded to the light source, then it will often encounter flicker. 

We are happy to confirm that our T8 LED Tube Lights offer flicker-free output due in part to the drivers within.

I noticed that you have T8 tubes in a (non-flicker-free) and (flicker-free) but there’s no price difference. What’s the difference between them besides offering a different kelvin? Is there a time a non-flicker-free bulb has its place? 

All of our T8 lamps are flicker-free, but not all of our pages will necessarily indicate this. The underlying product, however, is the same (i.e. PN 4024), so you will see that the flicker performance is also identical.

So I currently have my fixtures rewired for double-ended power. And I see your tubes are configured to be used on single or double-end power. As I look closer there’s a problem, your spec sheet says (shunted) tombstones are required. I have non-shunted tombstones as all double-end power rewire configurations I've come across state there's no need to change the tombstones as non-shunted or shunted can be used with double-end configuration. Will this configuration not work with your bulbs? 

W have reviewed our product literature and it appears that connecting the lamps using the fixture configuration you describe is permissible using both shunted and non-shunted tombstones. Please see below, with the red square highlighting what would be your wiring method:
