Lumintop GT4

A GT reflector, interesting… I am about to try a prototype driver with an XHP-35 and have been considering what to put it in… my thoughts lead me to wanting to build a light from scratch but I don’t know with what reflector. Can I get a GT reflector? Would I contact Lumintop or what?

I am selling my GT70, I just got it, still has the wrapper on it. Back in the box it goes. PM me if you anyone wants it.

Any possibility of the gt4 having a built in charger?

Not at this time, it was talked about but charging 8 cells in 4S series is no simple task and not one I trusted to a cheap budget option crammed into a light. Not to mention the stupid amount of time it would take to charge.

Better to just use an external charger.

To do it safely or “correctly” you would probably need to go the same route as other companies did such as Olight and Imalent. You’d need to have a sealed battery pack with a BMS (battery management system). Then you could charge it at 2A@19v for decent charge times.

I’m not a big fan of battery packs and most people on BLF aren’t either. So you have to decide which would you rather have, convenient charging at the expense of a more expensive battery pack where you can’t choose what cells you want or to run only 4 cells, etc… Or slightly less convenient charging, but have full control of what batteries and whether to run 4 or 8 celks and have cheaper costs.

So each option has their advantages and disadvantages.

At this point in time I don’t even know if the GT battery tubes would even be capable of running a battery pack. Is there enough room inside? Maybe they can use the existing tube and design a new tail cap with the charging port inside? IDK.

Makes perfect sense thank you.

Is there an update on the release date? Last I recall was sometime after the Chinese New year.

There are issues that need to be addressed with the prototype, so figure it will be some time before it is ready for production.

will the GT4 beat the R90C in lumens and throw?

Please see post from Texas Ace:

key word above “real” lumens
He’s referencing Matt (vestureofblood) who tested the R90C and the results were significantly less than Imalent claimed output:
R90C claimed 20 000 test result 15 274 difference –24% less
GT70 claimed 7 500 test result 7 537 difference +0.01% more

Watch this video and it’s easy to see that the Imalent is brighter but the output doesn’t appear even close to 2.75x that of the GT70

Hey TA,

I believe that currently the only direct competitor to this is the R90C but I’m curious if you think that the MF03 concept will be in this class also? At first glance the MF03 seems like it’s more of an X70 competitor with its 7x xhp70.2 and single xhp35 hi. However, from the photo below all of the 70.2 reflectors are smooth finished rather than the standard orange peel. Shouldn’t that all add up to something like 20 000+ lumen with 700+kcd?

Without some more details and/or test it is impossible to say exactly what it will do but just looking at it, I would guess less throw (the center xhp35 might bias that but the beam would be very different) and or course the possibility of higher lumens, assuming they have a good enough driver to power it properly.

my MF03 draft was made a year before i heared of the X70...

I think he meant more as a general final performance competitor vs a flashlight designed to compete with another light.

LOL

Correct.

I currently have a few big lights that each cover a rather specific category:
DX80 extreme output - high flood - medium throw
MF04 low output - no flood - extreme throw
MT03TA extreme output - extreme flood - no throw

The GT & MF04 created a new category of extreme throw - low output/flood
The GT70 & R90C created a new category of high throw/output - mild flood (due to spill)
-I don’t personally consider the MF04S in the above category given it’s reported less than 1 minute runtime on turbo. otherwise sure it’s in.

The GT4 looks like it could amplify the high throw/output - mild flood category into extreme throw/output - medium flood (due to spill)

The DX80, X80GT, MS12 & X70 are just output monsters with no realistic throw in comparison to the new 1 000 000+ cd category. The X70 makes only 311kcd and has extremely small reflectors so to me the MF03 looks kind of in between with it’s deeper smooth reflectors was my guess. Maybe like a DX80 with extra throw?

Anyway… I’m stoked for the GT4 whenever it eventually comes out. I really like the idea of a mild/medium flood, huge hotspot, mega thrower! My MF04 is crazy but in the dark I basically can’t see where I’m walking. My DX80 is also crazy but using turbo in the winter basically blinds me due to the sheer amount of light reflected back at me off the snow

Or maybe it just looks cool and I’m good at rationalizing why I need more super expensive toys! :person_facepalming:

MF04C?

“S”… corrected. good catch!

Okay, I thought they where releasing a new model. Lol

do we actually have any beamshots or info about lumen output, runtime and temperature of the GT4 or are we just speculating and waiting for it to be released?
