Lumintop GT4

The GT4 will be like the GT and GT70, setup for easy mods down the road. Although CFT-90 will not be a factory option for sure, just far too complicated and costly to be practical.

I am positive that there will be custom mods with this though.

what the difference in price between a CFT-90 and a average cost LED like the 70.2?

These are $100 per LED, roughly.

why so expensive, new type of led or ?

$15 per 70.2 vs $100 per cft-90. Also maybe $25.00 for 70.2 driver vs unknown amount, but I would estimate at least $100.00 for cft driver. Also, don’t forget that the 70.2 will have more output but lower luminance than the cft90 at max current. So most likely at least 400.00 more than asking price for base gt4 for a cft90 light would be what I would expect. If custom sourced it will be more.

The highest bin that Mouser has in stock goes for around $116 the last I checked… and bought! Because I had to have just one…

Not as simple as that. The highest bin currently available to buy is around $116. Then you somehow have to cram at least a 400W driver in that head. Luminus claims a maximum current of 27A for the CFT-90. and it has been tested at over 40A but with active cooling. I think it’s better to just have one CFT-90 emitter and take advantage of the increase cooling of the GT4 head so the LED can be driven to its full potential, instead of having four under-driven LEDs. Even with one, it won’t be a long-sustained max output. But I think it would be far better with this as a host than the original GT.

Incase this thread turns in to the request thread, I’m in for one.

R90C with coupon is about $280. I tested two of them with the TA tube with Maukka calibration. Turn on lumens was about 14k for one and 13k for the other. Newlumen tested his R90C at 16k lumens with the same calibration. The GT4 should make 20k+ lumens but throw might be a bit less than the R90C, unless the domes are shaved.

it will probably turn into the usual group buy thread later on when its time for that.

I picked up R90C last year for under $250. I haven’t tested it however it checks all the right boxes with it’s green batt lights, lantern lights, massive throw, and lumens in a compact size when compared to the BLF GT and others that have been mentioned. If the GT4 can’t outthrow the R90C then I definitely won’t be opening up my wallet for the big boy, super fins or not. It’s the high Lumens and throw combo that gets my attention. I guess we’ll just have to wait and see but I’m not a fanboy so it takes results in the end. Heat, size, and UIs aside those are two attributes worth the attention or don’t bother making it IMO.

Interesado

Me too.

Hello M4DM4X,

If it is possible at any time, please make Lumintop consider one (or more) Neutral White variant as well.

No one made a high CRI flashlight of this size, yet - my suggestion would be: 4500K CCT and 90 CRI. While XHP70.2 90 CRI is not especially good at rendering deep reds (rates around 50 for R9, while R9050 rated Nichias do usually over 65), still it would be a step up in this league (as an usual R70 ‘standard CRI’ emitter has negative values for R9), and it is not much lower in output /M2 vs P2 performance bin/)

+1… it’s perdy… I need a new shiny thing for 2019… sign me up.

While this is a super light, I think it would be cool to have an XHP 35 HI version. Could possibly get over 10000-12000 lumens and throw a lot farther…

I have also considered an XHP35 version, although I expect lumens to be more in the ~8k range based on the GT output.

Basically it would be GT70 output levels and most likely GT70 dedomed throw levels as well. So all you would really gain in the better tint of the XHP35. Not sure if there would be enough of a market to make it worth it.

Aaaand better heat management. I think with 4 XHP35 HI it will stay cool until batteries die.

That light looks amazing! Can’t wait until it’s finished
