If what he listed are the actual CCTs of the emitters I imagine mixing tints will be an option like it has been on other Emisar lights. That would make for many options in final temp (and with better tint too).
Ever since the original D4 came out, people have been asking for a specific type of light which Intl-Outdoor has not yet made — a single-emitter EDC-style light. Basically, a Noctigon version of something like a ZebraLight SC64 or an Olight S2.
The D4 makes about 4 or 5 cd/lm, while the D1 makes about 33 cd/lm. Between the two is a hole in the product line.
The goal would be to fill that hole with something as small as possible with 18650 and one LED — narrower and lighter than a D4, with thinner walls. The beam pattern would be about 10 or 12 cd/lm. Ideally, with a deep carry clip which is straight and runs parallel to the body. The body is probably about 21 mm in diameter, the head is as narrow (or almost as narrow) as the body, and the light is ideally under 100 mm in length if possible.
Something like this would work well with a regulated 5A driver. For the LED, it might make sense to use XP-L HI, XP-L HD, LH351D, or 4xE21A / 4xE17A arranged together so the LEDs touch each other.
The choice of optic or reflector probably depends on which LED is used and how throwy it is. For example, XP-L HI might work with a frosted TIR or a heavy orange-peel reflector, while LH351D might work better with a clear TIR or a light orange-peel reflector. It would require some experimentation to produce a nice-looking beam with the right amount of candelas per lumen.
This is essentially XHP70, XHP50, XHP35 under one single footprint which one can actually solder properly not having headaches with alignment in mass production of 4 different footprints. This is exactly why XHP50 in 3V is used for without wasting so much space with a wide base, time and effort.
And the beam pattern is not better than what those XHP type of LEDs have to offer.
I just want to second what ToyKeeper replied to this. What she and I are talking about is not a thrower, but an EDC light that’s more throwy than a D4. It may or may not have more maximum turn-on throw (it probably would using an SST-20), but able to do a given amount of throw (e.g. 5000 candela) with less heat and battery use. My first choice of optic would probably be a textured reflector, which loses a tiny bit of throw for a smoother beam.
The Lumintop FW1A is similar to what we’re describing, but I think Noctigon could do a better job. A slimmer host would be ideal, but the same host with a slightly longer head to accommodate the single optic would work for me.
I see no point in smoothing out a beam intended for max throw. An XPL-HI in a SMO reflector looks great to me - I have many modded XPL-HI V2 5D's and V4 3C's in SMO EDC's, all have a good look'n beam. SST-20's have to be CW/low CRI to get decent throw. The 95+ CRI SST-20's don't throw well.
