It’s impressive to get over 400m throw from such a small reflector, but for any appreciable illumination of the target, spill is going to suffer. What voltage and amperage will the driver be capable of supporting? I take it this is a single cell flashlight?
Unless you’re going for CSLNM1, CULPM1, or SFT40 narrow beam profiles, I’d pick XHP70… but would prefer XHP50 for the temp range.
NO sst70 or sft40, at least if they are CW. light is damn green. i perspnally would havent been intereted in them as tint is hell green. especially in sft40
xhp70.2 4000-5000K is great choice as well as xhp35hi with the same color trmperature.
i suppose that TIR optic version with some HI CRI leds would also be interesting
LOL, give them a choice of just two on BLF and you get twenty
Of the two choices in the OP, assumed that it will be cool white anyway, SST-70 is far superior: still great output for the size of the flashlight, not the extreme flooder that a XHP70 would make it, and super clean beam without tint shifts.
Btw, Skilhunt could make a prototype of both and see for themselves which is better. But I guess that for selling it, which one is better is less important than what people think is better.
I do not like cool white tints, but the SST70 that I tested (a sample that I got via LuckySun) had a straightforward cool white tint, not green or anything.
Most important question. Is this M400 driver 6V or 12V?
Short answer. Offer BOTH.
7070 footprint emitters are pure flood in this size optic.Pair the XHP70 (better yet Getian GT-FC40 hi-cri) with a Frosted or Pebbled TIR.
5050 would ideally be a Cree XHP50.3 HI. Range of tint and CRI options. Luminus SST70 is only CW and won’t gain as much interest here in my opinion. Future SFT-70 would yield best lumens*throw numbers
The LED that I think would sell this light to me is the Nichia B35AM in 9080 bins. But I’m guessing this driver is 12V…

Faremmo un semplice sondaggio per il fratello dell'M300, il nuovo modello M400. Verrà utilizzata la batteria 21700. Abbiamo opzioni difficili da fare una scelta. 1. Usa LED CREE XHP70, 4000 lumen 2. Usa Luminus SST70 LED, 3000 lumen o altre buone opzioni che potresti suggerire. Fascio più diffuso o fascio più focalizzato? Hai davvero bisogno del tuo aiuto e facci sapere come ne pensi?

I haven’t actually owned anything with SST-70 yet, but from what I’ve seen and heard the tint shift is as bad or worse than SST-40 and has greenish tint when run below high current with CC drivers:
These are the beamshots from my SST70 test, left with small S2+ OP reflector, right with smooth X6 reflector. The led was at 1A.
No tint shifts and the tint is about correct in the picture so there is something different here, maybe later production batches were awful?
In any case, if different tints are photographed in one picture as in the zeroair pic, the white balance for at least one of them is not as you see in reality.
