Normally I prefer make real runtime test than meassurements of tailcap current (runtime test is continuous test, and tailcap meassures are puntual data of current, will be interesting perhaps a runtime tailcap current, this would be more useful).
The battery will not behave like full to half empty, you can not make calculations: amps, time, runtime, lumens as a simple equation.
I suspected it was not linear math, but I hoped with Nimh battery that the perfromnce would be support such the ability for multiple 3 minute runs. I don’t know the mechanism for the drop down in light output (current draw). If it is simply time, I bet the NimH would support 30 minutes, or close to it, on high. If it is temperature, with long enough breaks between the turbo burst, I think the same still. I guess what I really wonder is with a 25% battery, can one still get a 2-3 minute linear turbo burst,or is the duration more like 15 seconds before it ramps down.
Thanks so much for this test!! I hoped/expected this sort of result. I imagine if this continued the light could overheat at some point, but I was more interested in the ability to be able to get turbo mode with a partly depleted battery.

Around 2:15 he turns the light off.
I would estimate only 1/2 sec of holding the button down turns it off.
About red, is not exactly as the Mi7 red, but is really very similar:
(I have bought now one unit in grey, with nichia. Also available in black if you do not like this red)
Hi Trevi_lux, the instructions you show above mention a dragon breath mode. Wondering if you have tried to exercise that on your light?
By the way, the review is simply fantastic. So much detail regarding the light. Thanks for taking the time to show us all about this light, and the others you have reviewed.
