Question about brightness ramping with Fireflies ROT66 Gen II SST20 5000K

As I was fiddling around with an ROT66 Gen II that I recently bought, I noticed that every time I ramp the brightness up it would stop at a certain point (probably around 50% brightness to my eyes) and not go all the way to turbo. I would have to double click at that point to access turbo. This would also mean that there is a spectrum of brightness (i.e. between the perceived 50% and turbo), in which I can’t access since there is some sort of a “ceiling” when ramping up. Is this normal for the firware or is it a problem?? Please help.

You can change this levels by yourself. The factory ceiling level takes 5A and produce near 2000 lumens.
And on this setting flashlight not overheat very quickly.
In inner logic this is is level100. And turbo with fet is level 150.
You can change ceiling level in any position, even 149.
Just read instruction, it is easy to setup ceiling level and even amoint of levels in stepped mode.
But i d.t recomend to change factory mode - in space between 5A and uncontrolably fet turbo this flashlight overheat extremely fast, so you lost light level anyway by termostepdawn. Just understand, that this is 2000lumen flashlight with ability to get around 8000 for a little time for extremal situations.
As exsmple i use it in turbo only except flash on foto.
