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.
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.
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.
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/)
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.
Think he said XHP35 HI version. For HI's, think it should throw in the range of the original BLF GT according to what others posted about reflector widths of single vs. multi LED/reflectors, but 4 times the lumens.
Yes… or, the throw of the original GT, but with 4X the hot spot. I have even considered doing this mod myself, even making a custom spacer that held four separate MCPCBs at a slight angle to each other radially, to effect a much wider hot spot at long range than simply having four coplanar emitters.
