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

Hi all,

Here is a quick comparison of the beam plus all my test results for CD/Lumen output.

Please let us know how you think this version compares to the GT4.

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

I feel these GT lights need to be renamed because they are anything but budget, awesome torch but unrealistically obtainable for people like me Crying

2,375 and 19,000: This compares very favorably with six other lights : X65, R90TS, R90C, HK90, MF05 and GT4. The closest spec cousin may be theR90C. Thanks for your very valuable review!

Because I like big lights, my flashlightical views lean heavily toward both the extreme bright and the extreme heft.

I think “budget” applies if you compare to other lights that can’t even do what these do. But the GT4 is absolutely obtainable for most people, I feel.

When I tell people an Emisar D4 would run them $55 with a cell, they laugh, hand the light back, and walk away.

Another great video Matt. So tell us, how did you manage to knock out your two front teeth? Did the front forks collapse on that chinese motorcycle at a bad time? What happened?

Thanks for another great video that allowed me to vicariously enjoy a light I want and do not need but I have been saving up for one.

Also, always wondered where the Tooth Fairy was when we needed them the most as I have dealt with similar dental issues.

How many flashlights does a "real man" need?

None, real men are not afraid of the dark.

I will get the GT4 which is a fantastic torch but the GT94 is way out of my range, Maybe in a couple years when they come up with something crazy like the GT96 plus plus 40,000lms at 3 miles lol lol. It’s just amazing from when we did the original GT group buy at 100 to what they are costing now.

It’s definitely well into super-thrower prices, which people are apparently willing to pay. But GT4 aside, what’s the competition?

The competing item in my collection is the R90TS. The GT94 has less lumens, but more throw. Also, the GT94 is the first light to have both significantly more throw and also significantly more lumens than the X65. One source of confusion: it looks like there are three contemporaneous topic threads for the GT 94 in this forum. Tat, ves and tex.

So looking at the R90TS specs, it appears to only have about half the cd? Then again I wasn’t seeing an amazing difference in the video, so who knows. Also it appears to step down from the competing 24,000lm mode at 90 seconds. My guess is that’s about as long as it can handle it? Apparently the GTs can go longer, if the thermal throttling is raised or… disabled! 

Lightbringer, didn’t someone find one that was 999 million? That one’s only a measly 9 mil.

So I watched Matt's review of the GT94 and saw his recommendation for placing the batteries into the carrier. I followed his instructions and reinserted the battery carrier. Light would not turn on. I then measured the battery carrier voltage @ 16.86 volts which looked correct. I then inspected the negative surface of the battery carrier. It had a oily film. After clean it with 99% alcohol and reinserted it, Light worked as before.

Clearly they’re just exaggerating. It’s probably no more than 950 million…

So the light worked, then the cells were inserted again, potentially in a different manner, then an oily film appeared? Do you find it anywhere else in the battery carrier? Like in those rubber things?

And you know, probably like the rest of the lights here they step down to about 15 million after 90 seconds unless you disable the thermal throttling.

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. Big Smile

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?

I would wait for more video comparisons. Hopefully he can do an update without the fog. But the video comes down to a couple of frames. There are probably better ones, but these are the ones I chose.

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

Not sure it’s a fair compare. GT94 might’ve looked more favorable if the lights weren’t ever pointing in a place where there’s already light. But I’ll admit even where I live that’s getting harder to do.

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. 

Because I like big lights, my flashlightical views lean heavily toward both the extreme bright and the extreme heft.

I could be wrong, but I think the distance is far enough to show off a good bit of difference. The key is a solid A/B compare, unlike my .gif above, where the target is dark, and we know between the two shots that the lights were pointed in the exact same manner each time. And like my .gif where the A/B snaps back and forth a few times.

If I were both rich enough to own both lights and buff enough to carry both lights, one thing I would do is get the camera closer to the target rather than the light. That eliminates the fog/humidity. Maybe. Either have an assistant switch the lights, or just set another camera up at the target to record at the very beginning.

I choose to NOT watch the video, because I know how it ends.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

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.

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.
