Lumintop BLF GT94 ( 4 x SBT90.2, 1.65mcd ) NOW AVAILABLE @ Neals: code NDGT94 gives $ 150 off

Nice results, missed those the first time

I have been told that it is ok over here to post live links to the other place, but being that I am feeling a tad conservative, I will post a link that does not directly connect the two realms to each other. Who knows, just one tiny spark could cause both universes to go thermo-nuclear atomic fireball.

No prob at all here, link all you want!

Just received the strap wrench for removing my GT94 bezel. Did a quick test and the bezel was loosened easily. Waiting for the smooth reflector.

Ok, maybe you are right and it is not a Buck driver, but this detail was not essential for what I wrote.

Definitely few persantage lost from SMO to OP reflector. Few guys measured around 1.55 Mcd with SMO reflector.

You have both reflectors? I didn’t see that comparison, which numbers were those?

No I don’t have. VOB measured around 1.55Mcd and Michael Searchlights on Youtube also measured around 1.55 Mcd.

Ah I got ya, I generally consider anything within ~10% from different people equivalent due to variances in a bunch of factors but yes, assuming all else is equal that is about a 10% difference. Just about what I expected.

I am guessing you would be hard pressed to see that with the naked eye (it takes 4x the light to appear 2x as bright to the human eye) and no side-by-side comparison so it will really come down to what beam style people prefer more I am guessing.

Yes indeed as you said.

I celebrated the dawn of the new flashlight day by taking a little trip with the X65, R90TS and GT94op. The X65 and R90TS both show the same amount of light on target at 650 meters, and the same maximum usable throw distance of about 800 meters. The GT94op bests the X65 and the R90TS by putting more light on target 650 meters, and by extending maximum usable throw distance to about 1,000 meters. The additional throw that the GT94op has over the other two lights is enough to make me very happy that I added this light to my power thrower collection.

Can someone with both a GT4 and GT94 please post some beamshots for short, medium and long range? Thanks

Kinda surprising to me that such an engineering feat as this light is receiving almost no love over on CPF. There are atleast 3 threads over there and no comments at all.

Anything from BLF is considered second rate on CPF for the most part in my experience.

I tried posting there early on but got threaten with a ban since I was from BLF and have not gone back since.

There are a lot of good guys over there but the management seems to really have it out for BLF for some reason. Thankfully a lot of those good guys also post over here.

Those Surefires are what seem second rate to me :smiley: . Honestly though this light is probably the highest quality light I have ever had. Seems right on par with the Maxabeam I used to have but much more useful. Seriously impressive engineering.

Thank you, I try to make each light I work on the best it can reasonably be. It is nice to know it is appreciated.

What changes need to be made to the GT70 driver to up the current for 4 SBT.90s in series?

Technically the GT70 driver would work as is but swapping the FET would be a good idea.

There are some other PCB changes to the GT4/GT94 drivers to beef them up and reduce voltage spikes and improve longevity but they are not possible to implement on the GT70 driver. The GT4 driver also has the programming key to make re-flashing easier.

Today, on the German forum, HARDUS posted GT4 and GT94 comparison beamshot video: https://www.taschenlampen-forum.de/threads/lumintop-gt4-incoming.68291/page-2#post-1088768

Thank you, HARDUS!

Just thought this thread might be interesting for some of y’all.https://www.candlepowerforums.com/vb/showthread.php?471366-BLF-GT94-vs-HID-LED-has-surpassed-HID-in-my-opinion&p=5423310#post5423310
