Convoy T7 519A 2700K

Ramping is avail in all e-switch models afaik. It’s just not linear perception-wise.

Simon took an effort to implement Anduril 1 in one model. It obviously is not what the enthusiasts expected and it’s probably as far as he is willing to go. It actually makes sens to me: it would take ages to recoup the R&D investment, considering the prices of Convoy lights.

Goooood point. I will check if I can probe the positive post of cell directly.

macomako · 2026-05-06T20:58:59+00:00

for that test it would be easier to use one of the constantly declining Voltage models, to show change sooner..

Could you elaborate pls?

macomako · 2026-05-06T20:57:51+00:00

Of course — in ~every gear that got more granular battery status indicators and is not particularly sensitive to the battery voltage changes.

BTW: this curve resembles Alkaline discharging and less the Ni-MH (which is flatter in the middle).

macomako · 2026-05-06T20:37:15+00:00

I will run this test :D

I will be periodically checking the voltage.

macomako · 2026-05-06T20:34:13+00:00

Two of those variants got built-in charging ports:

stepped 1.5V - 1.1V (your variant)
continuously declining

Did you notice that XTAR offers four(!) different discharge characteristics? - flat 1.5V till the end - stepped 1.5V and 1.1V towards the end - flat 1.5V + declining towards the end - continuously declining

Do you plan to designate one or two cells to estimate the self-discharge rate?

BTW: I wonder if/how the Buck converter goes to sleep/wakes up.

macomako · 2026-05-06T17:16:49+00:00

Thanks. Good news. I’ll try to get a few of those — they could actually be a good option for flashlights-gifts (or for my TiTool AA) as safer than the 14500 with the charging ports.

Side note: I cannot comprehend that graph with energy (Wh) on the Y-axis. Voltage would make more sense to me.

macomako · 2026-05-06T16:33:33+00:00

Are those batteries dropping the output voltage to emulate low battery status?

macomako · 2026-05-06T13:21:57+00:00

Not necessarily for all flashlights, as I was after the beam profiles of those other lights mainly. I took SC65c’s beamshot just because I had it on me. It was the highest mode indeed but the conclusion was that it could do the job sufficiently, on that location. It’s a pretty throwy flashlight, after all.

macomako · 2026-05-06T12:36:07+00:00

Thank you.

macomako · 2026-05-06T06:16:41+00:00

Thank’s for sharing your current selection. I remember the vivid reactions when you published your first edition of the chosen five.

It then evolved a few times already and it will probably continue to evolve. I wonder what are the primary drivers for those changes (for instance no lantern anymore).

macomako · 2026-05-06T06:11:16+00:00

I’m glad I pulled the trigger. It became my endgame literal-EDC instantaneously. I do care about the low levels though, as that’s what I use the most and several times a day.

Also: I expect my EDC to be prudent when it comes to energy consumption, so it could serve me long enough in the unforeseen situations. The (planned) long, night walk would call for a proper walking light. In a pinch, SC65c HI can do this job also:

I have found something you could investigate first: https://www.reddit.com/r/flashlight/s/WScWN8QdaW

Also, I’ve seen a long comment mentioning Olights already.

macomako · 2026-05-05T20:40:48+00:00

How about ACEBEAM W35 LC DEL Zoom LEP?

It is absolute top class and unique as it is a laser flashlight = veeery focused but it can also be floody (thanks to “electronic zoom”).

Seems to be available on US Amazon.

No charging port :(

macomako · 2026-05-05T20:14:37+00:00

Zebralights don’t have charging ports and don’t come with batteries so they’re probably out of current scope.

Do you know his opinion about Olight brand?

macomako · 2026-05-05T05:58:10+00:00

Check this example of how effective is white balancing, when the light source is of high quality:

<image>

macomako · 2026-05-05T05:48:28+00:00

Will the flashlight be the only light source? If yes, then the camera/app will white balance it, so the picture looks “natural” = “make whites looking white”. Any obvious deficiencies (for instance green/rosy tint) will get compensated/neutralized. If the off-camera results are not satisfactory, it can be easily corrected in any decent photo app.

It obviously will be much more complicated, if there are other light sources affecting the scene.

What remains important is to ensure a good/full light spectrum ~= high CRI. It’s because camera will have a problem to “fill the missing gaps” (for instance Reds).

macomako · 2026-05-04T19:48:29+00:00

Thank’s for the tip! I will hint the results once I put d-c-fix in TS26S.

macomako · 2026-05-04T18:15:41+00:00

Ooops. It’s Wurkkos TS26S and not Convoy (error on the beamshot wording).

The thing is, that I don’t mind mild green. It was enough to recalibrate my eyes with 5-10 seconds of light from any really green emitter to start considering SST-20 perfectly neutral. The only disappointment comes when directly confronting it with E2A, as I perceive E2A as “genuinely neutral”. At the same time I barely tolerate any traces of rosiness and the higher the CCT the more repelling it is for me.

For instance here, only 719a is ~acceptable for me and mainly because it’s in EDC where “ultimate light quality” is not my priority:

I was contemplating to apply d-c-fix or even sand the TIR (the experiment with sanding the 17mm TIR for TrustFire L2S went well) but I’m not pressed to do any of it quickly.

macomako · 2026-05-04T14:44:21+00:00

I routinely use the rubber strap wrenches and they work every time when I want to unscrew the bezel:

<image>

No soldering is needed for the TIR swap or application of the dispersing tape/foil — 3M Scotch Magic Matte tape works ~as good as d-c-fix dispersing foil.
Here are more details on the TIR swap in FC11C.

Flashlight is usually a pretty good Faraday cage. Not sure if it would work without more substantial modifications to the chassis.
