(prototype) the GT Mini

Originally, members were signing up via the form in the first post of M4DM4X’s group buy thread.

He recently said that public sales would start on Tuesday July 17, and that the password to purchase would be removed then.

It appears the GT mini is now listed publicly on the Neal’s Deals page of M4DM4X’s site.

thats correct!

please keep in mind the free flashlight draw includes orders until 22nd ;)

so what driver is the mini gt using then, good or bad ?

This is not the buck driver that we were promised with…
I bought it BECAUSE it was supposed to be regulated at 4,5A…
I don’t care for a hotrod, if the final version is a FET+1 driver it’s overpriced

Ordered one… :+1:



i hope i get answer to that question soon

Neal told me shipping starts next week - so you have a few days left to cancel
please use neal@m4dm4x.com to contact him for the refund.

That is most certainly not a buck driver, and I’m no longer excited for this light. It’s effectively a D1S that looks like a GT.

Regardless of whether this makes more sense with the factory emitter, what I was really looking forward to is putting a Nichia 119D/219D in one. Those emitters have a glass plate between the phosphor and the dome that’s very promising for dedomed performance in a thrower. They also have quite low forward voltage, making a FET driver pretty much a non-option.

I’m of the same opinion as zak; in fact I no longer want the light if it’s going to use the same FET+1 drive as the D1S - I’d rather have the D1S in that case, if anything. I’ve emailed neal to cancel.

I also ordered because of buck driver, otherwise it’s the same as the d1s.

I’ll wait to hear back on what the official word is…

Please confirm what type of driver will be in the GT mini BEFORE shipping them.
If it’s a FET+1 I’ll simply ask for a refund.
Why ? False advertisement, simply that.
If they choose to send it before stating what type of driver is in, then I’ll make a claim on PayPal asking for a full refund.
Why ? False advertisement.

I may sound irritated… because I am. I already own a D1S, no need for another one in a slightly different design.

It is a FET+1 driver.

False advertisement:
Lumintop copied the manual from the original GT and overlooked things.
I would say it is more a mistake.

Email sent to Neal to cancel my order.
Maybe I will not buy my FW3A after all… If Lumintop doesn’t know the difference between a FET driver and a buck driver…
The last user manual still mention a buck driver !

At 4.5A, an XPL HI would have an extremely high forward voltage of 3,75V.

A buck driver is almost useless for regulated output on turbo, which it will only do for a few minutes. To extend that regulated runtime on turbo, you would need to bypass springs, use a lower VF 4000k LED, use a better buck driver with a lower resistance.

Had it used a buck boost driver instead, I would have been fine paying 10-15$+ for the light. That would have made it the literally perfect pocket thrower of 2018.

On the other hand, I… for one… am happy about the driver change. I can simply flash Anduril and carry on. :smiley:

Since Narsil is so very different from Hanks IOS firmware, this isn’t much like a D1s at all. Much more refined, with a dramatically more advanced UI. Since I prefer Anduril and the IOS firmware is an abbreviated version of this, the ease of converting it to the firmware of my choice is a rare treat. Thanks Lumintop, nice upgrade. :slight_smile:

What a bummer.

For my part, I wasn’t planning to buy one of these — too many $ & I have an L2 — but the thing that had me considering it was the prospect of an eswitch buck driver @ >3A.

The L2’s driver is limited to 3A, but at least you have the option of running it 1s or 2s.

I added a notice to my blog pointing to that mistake

need to ask neal how that could have happened (I was not involved in the manual this time)

I am sorry if someone is upset :(

And now we all understand why I was concerned about being able to swap out drivers. :wink:

Now I’m gonna have to mod it (already placed and order during the pre-order invite) to get the buck driver…. hmmm. I’ll probably not notice much of a difference for my usage needs….Decisions, decisions….

I’ll have to send out to someone who can flash Anduril for me then if I decide to do a “soft” mod…

@M4DM4X

If I order an extra diffuser how would I know if it’s included in my first order (with the flashlight) or if will be shipped separately? I haven’t had any notice of shipment yet

I think the buck had merit for lower modes but I agree that perfect solution would be what you’re talking about and I would pay more for it
