You either just do not understand how PID and thin fast heating spring relates or you try to obscure it.
And I do not know all Armytek products, but Armytek Wizard Pro v3. USB has by far the smoothest, most stable steady PID in turbo from the three brands
you mention.
Olight H2R review (Headlamp/right angle, 18650, XHP50)
The thermal regulation is not very sophisticated. Instead of a PID controller the light just steps down hard when the head heats up too much. I measured this to occur at 55°C. If the light is cooled well and the head drops down to 43°C, it will momentarily reset and return to full turbo output for a short while. This results in a pumping output. The Armytek Wizard Pro v3 has a more elegant temperature control which keeps the head at a steady 60-63°C.
Armytek Wizard Pro v3 headlamp/right angle review (18650, XHP50)
“The temperature regulation works well on the Wizard Pro. With enough cooling, it can sustain output of over 1000 lumens until the battery is drained.
The boost driver is also excellent. I was able to access turbo with lesser batteries (NCR18650B) even when they were half drained.”
