This review says the T2 has PWM

This review says the Tool has NoPWM

Will comment about my testing only for the samples I have with me…

Old Convoy T2 uses PWM on lower modes (and it may be visible to some people), on AA NiMh and 14500 battery (14500 battery not officially supported though, says Convoy)

From my test, the new Convoy T2 does NOT use PWM on all levels, when using AA NiMh. when using 14500 battery, it does not use PWM on the lowest level, but I detect some kind of ‘fast PWM’ (I don’t have advanced instrument to check PWM — I use “shine light through a small portable fan blade and look very closely at signs of PWM — there is a pattern). In the case of the new T2 with 14500, the 2nd and 3rd level will have ‘fast PWM’ probably not visible to people’s eyes (I need to look very closely to look for it).

For the Tool AA 2.0 (I tested one with XPL-HD and another that came with XP-L2), I think my version of Tool AA 2.0 is from late last year, when they had both XPL-HD and XP-L2 versions of the Tool AA 2.0 (ordered at the same time, but the gray Tool AA 2.0 came with XPL-HD while the black Tool AA 2.0 came with XP-L2). These do not have the ‘lighted’ tailcap yet.

From my testing of these 2 units of Tool AA 2.0, when using AA NiMh, only highest level has No PWM, while lower levels have ‘fast PWM’. when using 14500 batteries, I can detect ‘fast PWM’ on all levels, including highest level. (using the ‘shine light through small fan blades’ method)

Anyone done current test on new version?

I’m curious how much current it draws from 14500 and nimh batteries.

Also haven’t found actual lumen ratings since this light had limited reviews.

> lumen ratings

Zeroair has AA Tool current and output data

I use Eneloop
I dont keep the stock Low CRI LED:

I give up lumens quantity

and gain CRI quality
and I still have enough lumens

There’s a lot of reviews for the tool AA but not with the new T2.

I got curious with the actual data since it performed well for me. Using it with 14500 and that 10% is enough for indoor use. 35% and 100% when outside. I only use nimh when I have to use it for more than 30mins outside. 100% all the way. Lol

I just find the other nimh modes too dim for outdoor use maybe because of the 4000k tint.

Anyway, I hope someone would post a review on YT or here in the forum soon.

these are my results with the new Convoy T2 (Nichia 219C)

tailcap current

1.5v battery (tested using a 1.5v Li-Ion AA – Vapcell P1418A)
1: <0.1 (0.02A?)
2: ~ 0.1A
3: ~ 0.3A
4: ~ 1.0A

14500 battery (tested @ 4.0v)
1: < 0.1 (0.02-0.03A?)
2: ~ 0.2A
3: ~ 0.67A
4: ~ 2.0A

The results I tested are a little different. However, please note that it is not a T2 product, but a new 4-mode T2 driver built into a different body.
The body is Ultrafire UF-T20, and the LED is XML T6.
Tail cap current.
NiMH (A)
1: 0.02
2: 0.13
3: 0.4
4: 3.2

14500 (A)
1: 0.008
2: 0.24
3: 0.7
4: 1.4

This driver is eccentric, it seems to be driven directly by a DCDC converter at constant current when using alkali and NiMH, and to PWM when using a 3.7v battery.
The PWM frequency is 31.62KHz, which is very high.

3.2A at mode4 NiMh????

Are you sure your driver is OK?

It seems that more current is consumed when the battery voltage is low in AA / NiMH mode. It is speculated that this is because the current value flowing through the LED is stabilized.
It is correct because it is a value measured at the same time with both a directly connected ammeter and a DC clamp meter.
Perhaps the driver built into the product and the driver sold separately have slightly different settings, but I feel that this 3.2A is excellent for turbo mode.

It did drain an eneloop pro for less than an hour in high.

Around 50+ mins of high then steps down to lowest setting that’s why I usually carry a spare.

3.2A at a bit over 1V is only around 3.5W. Doesn’t seem too much.
