[Review]Lumintop GT mini (18650 Thrower – Mini Giggles)

For the past few years forum members have been designing a huge thrower flashlight called the BLF GT, an 8× 18650 thrower. Lumintop was the manufacturer, and it was a great success, but very pricy. Lumintop decided to make a much more reasonable, smaller, and more affordable version which I have here today to review. The Lumintop GT mini takes what was learned from the BLF GT and shrinks it to a light capable of 1200 lumens and a throw out to 700+ meters, in an easy one handed pocketable light. Thanks to Banggood for sending this to me to take a look at.

Packaging
Lumintop typically has nice packaging and the GT mini, is no different. The brown box had an outer brown cardboard sleeve with a line drawing of the GT mini, the inner box just has the Lumintop name on it. No info on this light is listed externally other then if it’s Neutral or Cool white with a sticker on the end (Probably from Bagngoogd). Inside the light is packed in form fitting white foam. Accessories that came with my light were 2 extra o’rings and a purple unbranded lanyard. I prefer the orange lanyards that Lumintop used to use. A short 18350 tube is also available for this light. It’s a $5 extra to get it separately or get order it from the beginning for a few extra dollars.



Construction
Lumintop does a nice job with their lights and this is no different. It’s made from aluminium that’s been hard anodized in a near mat black. Threads feel nice, although they were dry from the factory. The tail cap is flat, but indented in the center. It looks like you could fit a thin magnet in if you desired. The lanyard hole is small as well but that’s not a major issue. The tail cap has 6 small flat areas to aid in grip. The light includes dual springs in the tail cap. Threads are fine, and have a slightly flat profile on top.





The body tube has flat diamond knurling that’s medium grip. It has some concentric areas turned in it to break up it into 4 blocks, and then 4 flats milled into it for writing and orientation. The spring on the head is short, stiff, and single :). There isn’t any physical reverse polarity protection on the head. The head itself has a series of rings with varying degrees of depth of cut to dissipate heat. The button has a silicone rubber feel to it and is slightly raised. Underneath is a LED that has various functions. The rest of the head is relatively smooth with small cuts for style near the edge. The reflector is deep and smooth. The LED is nicely centered. The front bezel is lightly crenelated and is not glued on. The lens is anti reflective coated.




My only build complaint is that the flats on the body tube, where the labels are for the light don’t line up with the power button when screwed all the way down so that the light is operational. Aesthetically this bothers me, but it’s also a small operational thing as well because I like the flats to line up with the button because it’s easier to find the button in the dark. Since this light by default has a lit up button it’s less of an issue. It seems not all the lights are affected by this by reading on Budget Light Forums.

Size/Weight/Water Rating/Size comparison
I measured length at 132mm, width at it’s largest at 50mm, and at it’s narrowest 23.3mm. Weight with an 18650 battery is 200 Grams. The light is rated for IPX68.

In comparison to other throwers, The GT mini is the same length as the Thrunite Catapult V6 but the head is head and body tube are smaller. Compared with the Convoy C8+, the GT mini is a good deal shorter (no tail switch), and has a slightly larger sized head.

LED/Runtime
This light uses a Cree XPL HI LED and is available in cool or neutral white. Mine that I am testing here is in neutral white which is my preference. This is pretty warm for neutral white which I don’t mind. Probably around 3800k or warmer. It uses a FET driver to achieve around 1200 maximum lumens in Turbo mode.

For runtime I used a 3400mAh Protected Thrunite battery. Step Down was pretty fast and pretty agressive on this light. It really stepped down pretty low and quickly after 2.5 minutes. It stepped down again at 3.5 minutes to 10% relative output. This is great for thermal and overall runtime but less practical for actual use. It requires you to either bump up again repeatedly to get brighter levels. Overall runtime was over 300 minutes but this was at about 10% relative output. Heat was not too bad, the head got to about 105F.

UI
This light uses the popular NarsilM V1.3 firmware. I won’t pretend to be the expert on this firmware as it offers a lot of options. It’s a firmware designed by enthusiasts for enthusiasts. What I like about it on this light is that it’s ramping, meaning the light doesn’t have predefined levels by default. This can be switched if you don’t like ramping but I will stick with the default for this review. The manual does a nice job of explaining the firmware. Full ramp from low to high is about 2.5 seconds. The light flashes at the top and bottom to let you know where it is. It has a shortcut to turbo if you double click. If you double click again from turbo you get into the strobing modes, and double click to exit. The switch has a green LED under it, this is on when the light is off, but not when the light is on. This can be turned off with turning the light on and off in rapid succession. Battery status, and lockout are also available, as well as momentary. It really is pretty much all here including setting the UI back to factory default. Make sure to give the manual a read or two to make sure you have a grasp of the capabilities.

Pro’s

  • The Neutral white version is a pretty warm tint which I like.
  • Lumintop have a nice build and packaging quality, on par with an Olight or Acebeam.
  • Glowing power button
  • Manual is different (in a good way vs the standard ones from Lumintop)
  • Great value thrower
  • Small 18350 tube available and included in some versions of this light.

Con’s

  • The body tube has flats, with labels and they don’t line up with the button, this is annoying to my “OCD”.
  • Large and Aggressive stepdowns in the runtime
  • Large head, small body tube makes it a little less ergonomic. I imaging this is even more so with a 18350 tube (Disappointed on isn’t included).

Conclusion
At the current sale price (With coupon) this is a high value thrower light. Unlike it’s big brother the BLF GT, the Mini is affordable, and easily fits in one hand. It offers great firmware, good build quality, and a long runtime even though it steps down a little fast for my liking. With the 18650 body tube it fits fairly well in the hand, but I can imagine the 18350 tube will be a little weird to hold on to, and get fairly warm to hold. That said I will probably buy one because of the novelty factor on my next Banggood order. With all the new throwers out this year, the GT mini ranks high on my list because of it’s firmware and neutral white options and that its been heavily influenced by enthusiasts.
