BLFGT94 vs BLFGT4, loads of beam shots GT94 NOW AVAILABLE!

Yes, the light works properly again. No, the oily film just didn't appear. It was already there, I just didn't notice it before.

UPDATE: The threaded aluminum ring that is fitted between the battery carrier's negative surface and the negative contact surface of the circuit board was not fully tightened down.

Recommended things to do with you GT4/GT94 to guarantee that the power is getting distributed to the flashlight head properly:

  1. Insert the batteries into the carrier as recommended by Matt's review video.
  2. Clean the battery carrier's contact surfaces with 99% alcohol.
  3. Tighten the aluminum ring that is fitted between the battery carrier's negative surface and the negative contact surface of the circuit board.
  4. Clean the aluminum ring contact surface with 99% alcohol.
  5. Reinsert the battery carrier and light up your night. :D

Sure the BLF GT seems weak compared to the GT4 and GT94 but those 2 in Cool White have way excessive backscattering light for my test hence I still appreciate my BLF GT Neutral White, a lot.
I would have like the GT4 design and project to be completed earlier, maybe a few months after the BLF GT in order to give a chance to a GT34 Neutral White (4x XHP 35 HI) to exist.

I’m torn between these two amazing pieces of technology now, neither of which I need! The GT94’s price is eye watering even compared to the GT4. 1300M of throw with huge flood sounds more real-world useful, as I doubt I will be carrying binoculars in order to fully utilise the GT94’s capabilities.

Any thoughts on my dilemma?

Thanks for that! From those two frames the GT4 looks good to me, the brightness of the flood is crazy.

The two frames on post 19: Yes, the targets are already self illuminated. Also, the distance doesn’t do the GT94 justice. At two dark targets, one 750 meters away, and another target 100 meters away, the comparison would show that the GT94 puts much more light on the more distant target, but the GT4 puts much more light on the closer target. The difference between the two lights is that one light is designed to put much more light at a target much closer, and the other light is designed to put much more light on a target much more further away.

Got DHL tracking number for my GT94.

I choose to NOT watch the video, because I know how it ends.
(wannahave, wannahave, ©metoo, ©metoo, ===> big dent in budget) :cry:

Anyone aware of the Lumintop BLF GT3 on Neals website Lumintop GT3 3xXHP70.2 18000LM 1370m LED Flashlight – Nealsgadgets?

No, I was not aware, but now I am fully aware that John in Cypress, United States purchased a Lumintop LM10 Copper Brass 2800lm EDC LED Flashlight 48 minutes ago.

The design is nice, the performance must be similar to a Q8 modded with 3V XHP50.2’s.

After owning and selling a few high power lights, I personally like the beam of the original BLF GT in that video comparison.

Finally got my SMO reflector from Neal. Replaced it. And……
Results as followed.

OP

Measurements were done at 2 seconds from startup.
SMO 1.583Mcd
OP 1.4Mcd

Thanks for the direct comparison!

That sounds consistent with TA’s observation that an OP reflector does not overly affect throw and can be preferred over that last bit of throw if you like a nicer beam.

My pleasure

…ha ha ha :smiley: :smiley: :smiley:
I had the R90C,then I saw the R90TS,so I got it,and then I saw that Banggood had a flash sale of 55% off for MF05, and so I grabbed it as well.
Now I think for one of the two finals of the great parade,ie GT4 and GT94 and I try to resist buying one of them also.

I’m contemplating in getting your flashlight. How do you like your GT94 so far? Do you recommend the CW or NW? Any upgrades you recommend? Thanks in advance.

Personally I prefer the cool whites when I have a choice. Visually they “look” brighter to me and in most cases I like the color of light better. There really are no upgrades needed on this light IMO. It was designed by BLF members so its more optimized than 99% of the lights on the market.

What batteries do you guys recommend?

I tried using the Molicel 18650 P26A flat tops and it doesn’t work.

VTC6 button tops or something comparable work great.

Just bumping an old thread with a mini review…

I recently acquired a used GT4 and am rather blown away by the amount of throw such a “flood monster” delivers. While impressive in Matt’s clip, the effect is even more inspiring once held in hand. The odd shaped beam pattern becomes unnoticeable in the field, and the wide, long reaching swath of intense light becomes evident. Equally impressive is the sustained high output achieved, thanks to the simplicity of a proper thermal path with enormous surface area, transferring heat through a multitude of large fins. The entire head gets hot (not just the area surrounding the floor plate) and effectively transfers heat without any noticeable thermal bottlenecks. Once at high operating temps, placing my hand above the head reveals a large column of heated air rising. Thats not true for most all other high powered lights. Those silly little fans and fins dont do much of anything but provide an aesthetic gimmick to complete the sale to the unknowing. After those other lights quickly become heat soaked, they throttle power before the first minute to prevent melt-down. IMO, those are beyond silly and worthless, and the industry is flooded with them. But as long as people are buying them, they will continue to be produced.

Im finally at the point where I must consider how much throw is actually useful and how much more often I enjoy using my high-lumen flooders… especially one that remains silent, doesn’t use ridiculous proprietary cell packs or throttle down after 30 seconds. My BLF GT and SBT90.2 lights might never come out of the closet again!

Ive considered a 70.3 HI swap but decided against it. For my usage case 99% of the time, more throw at the expense of flood would be a huge detriment to the GT4. Side by side with my friend’s GT94 in the field, he wishes he had bought the GT4. If I were to describe it, the GT4 is a 32,000 lumen hybrid flood/thrower that can sustain turbo power for about 10 minutes (as long as you’re walking with it to allow airflow through the fins). Heat is also easily manageable by testing the heat with your finger and bumping down the power level a bit… while still putting out an impressive amount of light. Pick your poison… but the high efficiency of 4 x XHP70.2’s projecting through 4 large reflectors while illuminating a wide area, is far more useful to me than any number of SBT90.2’s ever could be. The GT4 already throws a great deal farther than I need or could use, and I seldom find myself standing atop a man made precipice, desperately trying to illuminate some distant man made object beyond the range of human visual acuity. For those that find great value in that sort of thing, Im glad the SBT 90.2 version is offered to get the job done and bring grins… or is it giggles? I own night vision rifle and spotting scopes that do a far better job spotting distant objects at night. The Bottom Line: with so many options available these days, its a great time to be alive for the flashaholic!

After the thrill of the GT4 wears off, I might buy another and modify the pair to use on the front of my Jeep (already equipped with a 135 amp alternator). Eh… just a thought, but if the price is right, why not? I already own custom automotive rated linear drivers for the swap that output 13.5A up to 14.9V + remote thermal throttling for both the heat sink and driver, all dimmable by rheostat. Possibly 2 x HD and 2 x HI XHP70.3 per reflector to mix it up a bit.

Anyone want to get rid of their GT4? Shoot me a PM…
