[M4Ddeal active] : Lumintop GT Mini - 2 authorized deals

any idea on specs for this light?

Signed up for NW with the short tube. Only interested if it comes with the short tube, thanks.

About 1300-1500 lumen and about 120 kcd

short tube is a extra to buy

18650 is standard

Where to buy one in China?

ask Neal@m4dm4x.com

Hi Martin, one for me please in CW w/h short tube thanks.Already inserted in the form however.

How do I add 2 more? Fill out a new form for 2, or the new total wanted?

no Problem to order more - we make enough ;)

but if you fill out your additional need we have more precise numbers and you just get (maybe) 2 identical mails

Added 2 more NW with short tubes.

This is what I was waiting for. Get constant output for at least the first part of the battery life, and should be more efficient that a FET driver on medium modes.

I’m in for one in Neutral White.

Who and where is that qoute from?
Are you saying you would want to use 2 x 18650 batteries? That does not make sense to me. One cell is not enough voltage overhead to use a buck driver, is it?

One cell is more efficient using a buck driver than it is with a FET driver, especially on lower modes. A majority of higher-priced factory lights using 1x18650 and a 3 volt LED use buck drivers.

It will result in a significant improvement when I get one and put a dedomed Nichia 219D in it, which has much lower forward voltage than the XP-L HI.

I have zero intention of using the GT Mini on any mode below 3.5A. Lol This seems like a long distance only light. There are other lights for use at lower levels, ones with bigger hot spots. There’s no need to mod this light in my opinion. (Unless it’s to increase output)

Sorry, I pulled that from theanual M4D M4X just posted. One cell is enough for a buck driver, but it will eventually drop out of regulation when the battery drops below the forward voltage of the LED. But at least you get stable output for part of the runtime, unlike a FET where output constantly decreases.

I looked around real quick to see what kind of amp draws you get on an xpl with FET and high drain cell. It seems about 5.5A to 6A.

So if the GT Mini is rated at 4.5A, maybe they are trying to make a buck driver instead of using a FET. Does that sound plausible?

Did you read Delta_V’s answer ?
It says IN THE MANUAL that Lumintop use a 17W 4,5A buck driver in the mini GT

Oh, sorry. I didn’t know what manual he was talking about. I haven’t read it myself, yet.

Good, now we know. :+1:

I relayed this info to the other GT Mini thread.

we add the Convoy C8 holster for 3.99 to the ordering page ;)

upload pics later
