Lumintop GT Mini (Thower) Beam shots and more!

Yes i understand, was just asking, i realize even cw maybe not topps 1300 lumens, its a nice light i really enjoy using mine.

Differences in measurements result from many reasons. Not only from the methodology but also from the differences between the various models. It can be affected by the ambient temperature, the battery used, the centering of the LED …
GTmini has a FET driver and the internal resistivity of the elements is very important here. The manufacturer gives 17W and 4.5A. My GTmini with Samsung 30Q received 5.8A (clamp meter). This is one of many possible reasons that the end result may vary. Measurements are made with the X-Rite Eye one Pro calibrator which is more accurate than most cheap light meters. Thanks to this, I can also precisely specify the color of light which in my opinion is one of the most important features. If someone thinks this is not very reliable, then he has such a right, but to call me a liar?

I think Mortuus was just confused with 2 different lumen measurements. No big deal. Nobody is lying.

Tell me about the eye one Pro. Is it just for measuring color or does it also measure lumens?

This is a calibrator for monitors:

Thank you very much komeko. This thing holds its own against my 5000K M2X mod.

I am very impressed with it.

What size driver / MCPCB does this light use?

BlueSwordM · 2018-12-18T04:10:26.000Z

20mm MCPCB, 17mm driver.

Thank you.

It says it has a 4.5A FET driver. Does this mean direct drive or constant current. If I put an Osram KW 1mm in it will i need to replace the driver? and will it take an acebeam 3100 protected battery?

It’s a FET driver so the amperage it’s pulling will vary based on the battery and led.

It fit the longest cell I had which was 69.5mm.

Details are here.

Looking by the throw of your flash, i guess i can compare it to this one, i have used while camping and it really has a good throw plus it has a stun gun in case of an emergency, here have a look “Flash Light + Stun Gun”

For some reason the switch on my sample was malfunctioning. It would not detect presses and sometimes it would detect two instead of one. I loosened the bezel a tiny bit and it’s working fine now. I also opened and closed the bezel yesterday so maybe that’s what caused the problem. Has anyone else experienced this?

The switch bezel? If so, sometimes the clearances on the wires solder pads is very tight - might have been a partial grounding on the exposed wires at the pads.

I mean the head. I took the reflector out and put it back in. I didn’t tightness it more than it already was but it made the button/driver behave strangely for some reason. After loosening the bezel a bit it’s working fine.

Visually, how does the GT mini compare with a C8 XPL-Hi? Better, same?

BlueSwordM · 2018-12-30T23:33:10.000Z

Quite a bit better in terms of throw, and better UI with NarsilM.

It’s also smaller with a larger reflector.

klrman · 2018-12-30T23:38:16.000Z

Thanks BSM. Been thinking about getting one for awhile but still holding back as I have my V6 to play with still.

BlueSwordM · 2018-12-30T23:45:28.000Z

Don’t buy the GT Mini then. You’ve already got a super mini thrower like the V6.

Money not spent is money saved

A quick comparison.

The Catapult V6 is a:
Bigger light
Bigger led
Bigger hot spot
Bigger power (assuming it lives up to specs)
Bigger price
Same throw distance

The GT Mini should be very similar in performance to a FET driven C8 xpl-hi light. Of course, the interface and UI is going to be different.

Agreed :)
