It’s possible that Simon hasn’t updated it yet as you can see the same thing in the T3 Ti/Cu specs but this review suggests that it may be a linear driver when using a 14500 battery.
That run time graph is dead flat. It’s not FET. Hope someone can take the driver out and look at the construction to see what type of driver it is for Li-Ion. Probably FET operating in linear mode?

There’s pictures of it, on his site:

2 inductors means it’s either a buck boost or 2 separate buck and boost on the same PCB.
8 Thanks
Yes that’s really good. Simon should update the product page to say boost for AA and buck for 14500 or boost/buck for 14500. This is a really nice product. Well done Simon. This thing is almost the same form factor as the Acebeam Tac AA but cheaper and has a better driver. Looking forward for a Sand or even better, a colorful one.
I will be sure to grab some when I’m back from a trip. Currently can’t receive packages

Hi Simon,
Can you share the details of the reflector in T6 compared to the S6? are they similar in diameter and depth?
If T6 can fit a 20mm TIR that would be so good. The reflector seems pretty deep so the spill will be very narrow.
2 Thanks
Unfortunately I couldn’t think of a 20mm TIR that can fit, from Carclo or Convoy or anywhere else; they are all too short.
From the product photo, this T6 reflector has a 5mm emitter opening (i.e., the length of the parabola’s latus rectum), which is identical to the S6 reflector. It seems to also have the same frontal diameter as the S6 reflector. Therefore, the two reflectors must be identical, since the parameters (1) length of latus rectum and (2) diameter of frontal opening uniquely specify a truncated parabola, with (1) specifying the dilation/scaling and (2) specifying the truncation.
3 Thanks
This flashlight’s origin lies in the ask for a AA light that uses the S6 reflector. So it likely is the same reflector. But I asked Simon above to confirm
2 Thanks
Yeah, this gotta be one of the most promising dual fuel drivers out there rn apart from maybe Zebra and D3AA. Also, Simons clicky UI is good and proven.

I’m willing to add some spacer so a TIR can fit. I like flashlight with a bigger head more than a tube light. This shape is really pleasing to my eyes.
If you could add maybe 8mm of spacer between shelf and PCB (to compensate for the S2+ and S6 reflector height difference), I don’t see a problem.

I really wish someone like @thefreeman would do some tests on the AA/14500 drivers. There was some circumstantial evidence a while back (discussion here) suggesting the T3 driver has lower efficiency than the T2 driver for NiMH, but nobody could say for sure.
These runtimes from ZeroAir (T2, T3) suggest the same conclusion: the T3 driver sustains 45 lumens for 265 minutes with a 4000K 519A, while the T2 driver sustains 49 lumens for 369 minutes with a 3500K LH351D. Integrating the lumen-hours suggests that the T2 has a overall system efficacy of over 51% greater compared to T3, which is more than can be explained by differences in emitter efficacy.
Perhaps the difference is partially attributable to different batch/age of the battery used in the test, but I think the driver is worth a look. Hopefully the new drivers are more efficient.

The new T7 is out (almost). I’ve been waiting for this light. I see it has the lower spec 1.5 amp driver compared to the T3’s available 5 amp driver.
6 Thanks
Nice to see 14500 flashlight with USB-C 
It would be nice to get a real moonlight mode on the T7 and it’s curiously missing a clip etc. But it does look rather interesting.
The T7 is interesting given the low price and USB-C charging on AA/14500, which is rarely seen. I would like to see a more balanced default optic (probably a reflector), a pocket clip, and a proper moonlight mode.

The Nlightd E1 uses a similar driver.
Simply awesome! I’m not elderly (at least hope not at my current age) but, I am a child I guess relative to my Mother and Father.
I see two or three of these coming my way!
Simple UI for me too! Love that option.
Every dang flashlight in existence DOES NOT NEED ANDURIL!
