(2) Low voltage protection: When the battery voltage is between 2.9 and 3.1V, the flashlight will alarm, showing a weak brightness with 2 flashes per second.
(3) Reverse battery protection: the battery will not light up, but there will be no abnormalities, no need to worry about burning the battery or circuit.
Which of them is stating the truth or are there different variations?
2) I tested that with an old AA battery and got it drained to below 0.7V without any warning beside the lower light output so obviously no low voltage protection
3) According to what i have found when trying to reverse engineer the T2 driver (in that thread) there is no reverse polarity protection. A reverse voltage would likely fry the two switching mos (because of their intrinsic reverse diode) if given enough current
Mmm souds to me like a "up to now i am ok, says the guy at the 4th floor while falling from a 20 story building" ;-)
The driver is a boost only thing so all what is left for limiting the current in the led when beeing fed with 4.2V are the serial 0.2 ohm resistor and diode.
It is not intented to be used with li-ion so it might work some time but i would not rely on this
So, here are some photos of the T2 in comparison with other Neutral white beams.
What I can say is that mine is mostly on the rosy side, not yellow. However, in a white wall you will notice the yellowish in the hotspot and also a bit in the corona.
Higher voltage (with 14500 cell) would probably annul that and make it mostly rosy and white (similar to what happens with Emisar D4 XP-G2 S4-3D)
T2
Left to right:
Sofirn SP10B (XPL-HI U6-3A, OP reflector) >>>>> Convoy T2 (XP-G2 4500K, OP reflector) >>>>> Nitefox ES10K (XP-G2 , NW)
In this comparison, the Sofirn has the most “white” beam, then the “rosy” of Convoy T2, then a “warmer white” for the Nitefox.
