(prototype) the GT Mini

Thanks! I knew I’ve seen it before, but I don’t think I’ve seen the in depth description of the build.

Very nice DB!

Throw (135,000) x 4 then take the square root for the answer…. 135,000 x 4 = 540,000 The square root of 540,000 is 734.85 so that’s the Meters in throw from the 135Kcd lux reading. (for those that don’t know already) This means that at 735M the amount of light hitting a subject will be similar to the light falling on same subject from a full moon. I’ve always meant to use a matchbook with a phone number written inside, could someone read that phone number by the light from this thrower at that distance? I found it to be true when testing the GT at over a mile across the lake, you could indeed read text illuminated by the GT… even at 1.1 miles distant.

If you look at a full moon it just looks white, the eye’s pupil contracts and adjusts for the brightness, but if you set a camera for the light the moon reflects onto a subject on the ground then point the camera at the moon your image will be blown out. Similarly, even from over a mile away the GT is amazing to look at! :slight_smile:

Here’s the light meter, illuminated by the GT from across the lake, showing half a lux….

Thanks Eraursis1984, it was one of those projects that sort of got out of hand. lol Been wearing it around my neck for over 5 years now. :smiley: Rebuilt drivers for it multiple times, it now has a Nichia 219C at 5000K making some 711 lumens from the little 10440 cell. :wink:

Will be interesting to see what the finals are on this little miniaturized version of the GT, I don’t have the GT anymore so this will fill it’s shoes nicely. :smiley:

Y’all know I’m not saying the Mini GT will throw a mile, right? But following the tradition of it’s big brother it will still be a nice throwy light. :wink:

It’s a bit more 734m
Sorry for the confusion

ANSI value:
Square root ( 135000 cd / 0.25 lux )

Interested!! Looks cool. How does it compare to a C8s though? Just curious
Throw wise

And it’s not even out yet duuuhhhhh Mikeadoo!! :person_facepalming:

No need to be sorry I was dumbass when trying to calculate, but thank you for clearing it up. Also thanks to jason and Texas ace for the insight and explanation.

Oops, Texas_Ace is not even on this thread. Looks like you mixed up the two Texans. I did that once myself.

Off the top of my head, I can’t think of any examples. What did you not modify?

should be alot better then c8, almost twice throw i think. C8 has like 70kcd vs minigt 135kcd.



available in the groupbuy July 2018

The proportion looks a bit off on that picture on the box.

Head should be a little bit bigger.

And here I go again being a dumbass
Sorry DB

sexy so gt-mini is the name then, i think its perfect!

The micro USB usb port would be very useful.

Um, well, um, Rey’s brass pineapple and at the moment a Nitecore TM16 are both sitting here in stock form. I don’t tend to modify a Sinner. If that helps. My S1A Baton in copper as well as my Jet-II Pro in copper are unmodified. And my Godmes T01. The Sunwayman F10R is still stock too. And my Dad’s Thrunite Titanium, the little twisty, it’s stock. As is my Titanium Olight S1 Baton with my name on it, from the X6/X5 group buy. And my number 62 X6/X5 set are still in the box, put away. :wink: And of 200 lights that’s probably about it. :stuck_out_tongue:

Even my Ti Core from MBI is modified, I put an Australian Opal in it for the switch button and inset a purple tritium vial inside the Opal. :smiley:

But I won’t be modifying the Mini GT (unless of course it needs it. :stuck_out_tongue: )

I think it’s looking great, don’t see why it would need anything as Lumintop is pretty much nailing it. Is changing the emitter to a more preferable tint considered a mod? I don’t ever worry about ordering the right tint as it’s usually so easy to change once the light gets here and is tested. I do like white, pure unadulterated white, no blue, no green, no yellow or orange or brown. Is that so wrong?

Thanks motuus! :smiley:
I want one for sure

Small correction - it will be about 1.4x the throw of a C8. The intensity is doubled, but there is a square root in the equation for throw, so you increase the throw by SQRT (2), or about 1.4.

If you want double the C8’s throw, you’ll need about 280,000 cd.

These numbers seem a bit suspicious. What C8 does 70kcd? Is it one with a xm-l2 or one with xpl-hi?

The Convoy C8 with xpl-hi and 2.8A driver surely wouldn’t have half the candela, would it?

The output difference would be about 350 lumen and the reflector is 5mm bigger in diameter. Is that enough to double the candela?

Mortuus meant twice the candela, not twice the throw.
