Lumintop GT Mini (Thower) Beam shots and more!

Nice catch! :wink:

Tom
Texas Ace used a NarsilM 1.3 Beta
I think you did provide it.
Maybe to Dell?

Ok, probably posted the v1.3 BETA for him to use on Nov 16th, then on Jan 28th posted a v1.3 with the "new" S42 support, but nothing seemed to come out of that, least not so far.

Tom E
you have a PM

Ok, these issues I think are explained by them using a different firmware revision then I planned on. The final firmware I sent them should be as the manual states but I sent then an earlier version that is closer to what it sounds like ya’ll are seeing. They were supposed to of used the latest version but it looks like it didn’t make it into production.

IIRC these are about the limit of the changes + some minor changes to the ramp / mode spacing between the revisions.

Yes, it was from me, although it looks like they used the prototype firmware I made for testing it instead of the final firmware with the refined ramp / mode groups and other settings. Not a big deal but the things mentioned above are a little different.

Hi, I hv a mod Acebeam l16, love it. How does the lumintop gt mini’s beam patter n throw compare?

Would it be alright to ask, what are the differences between the "proposed" final firmware you intended, compared to what is actually installed on the GT Mini?

Sharing a video beamshot of the GT Mini neutral-white:

(building on the other side is about 160 meters or 400 feet away from the flashlight)

compare to an Astrolux C8 (XPL-Hi 3A NW, 1300 lumens)

Basically what I said in the quote, I don’t remember all the changes but the biggest change was an improved ramp that was smoother, better mode groups and a few minor tweaks to some other settings that were really just from my drive for the best I can do.

A few of those changes were noted earlier, the menu timing was extended to 16 seconds instead of 8 seconds ect.

Overall most will not notice the difference, the base firmware I used was basically the GT firmware so it still works fine, it was just not optimized for this driver and light.

Yeah. So far the most noticeable part is, when stepping down from FET to 7135 due to low battery, the light is actually becoming brighter. This is because the firmware avoids activating two channels at once, and when the battery voltage is low, the FET can be darker than the 7135, thus “stepping-down to a brighter level” can happen. This can certainly be fixed by tuning the voltage that triggers this.

Yes, that is a possible issue with how it is setup now. A minor but notable issues.

This firmware was just meant for prototyping, it was never intended to be used in the final driver.

i have booth, gt is slighty longer but better lies in hand. emisar is more powerfull. booth are great

you might be right about the d1s. I dont have a mini gt or calibrated lights for the tube… i measured d1s cool white @ 1400 lumen using Sony vtc6…

emisar is not more powerful, i think the beam on gt mini is slightly sharper.

i have booth light, have you too?
my emisar is more powerfull

Why is it?

They are both FET drivers and the same emitter. Maybe one has a better battery? Have you checked their amp draw?

well no but i want to believe so :slight_smile:

I have a d1s… the beam is tight and intense… can’t say about mini gt yet… hopefully it will be good.

Not an apples-to-apples comparison, but here I got some images of GT Mini CW vs GT Mini NW and also Emisar D1 V2-3A

GT Mini CW (left) vs GT Mini NW (right)

(building is about 125 meters or 400 feet distance)

The second pic has the D1S (3A) on the left and GT Mini (NW) on the right.

For some reason, the GT Mini (CW) looks a bit less bright or focused than the GT Mini NW or the D1S 3A. Maybe it's just the more neutral tints look better at night?

Distance according to Google maps: ~126 meters or ~400 feet (actual distance is a bit more, because that is ground-to-ground-distance, the actual is from a lower ground level pointing several stories upwards to the opposite building at a slight angle)

This is what should happen actually, given equal outputs the neutral white will throw better. The warmer wavelengths are less prone to refraction in the atmosphere and thus travel further.
