Emisar D1sV2 respectively Noctigon K1

Surely we will offer this option is this LED can be sourced.

Hank, if you can source any A or D tint XHP35 HI 80CRI, that would be awesome. If you offer it with the good bins, I’m sure many people will buy multiple emitter versions of this light.

The 45E is very nice, though for throwers, a little warmer is more to my liking, e.g. 40E. I have that one in an Acebeam L16.

Hank
How this this compare size wise to a GT mini?

That’s exciting for such a small package

I wouldn’t mind this one either even though it’s a lower flux bin. Both are nice.

Head is 70mm. Dunno the length but I’m expecting around 16-17cm.

hmmm
A fair bit bigger than the GT mini…
Still pretty small… bigger reflector, more lumens and kcd than even my Vin’d GT mini… I’m excited…
This will out punch my Varapower turbo 2.0!

this is exciting, I am falling in love with the emisar d4sv2 I picked up recently… a super throwy one would be amazing.

I wouldn’t mind a lower flux bin too but hope the tint is below the BBL. That’s what made the D1S and the GT Mini so nice because of the beautiful A or D tints. Also the Mateminco MT35 / Astrolux MF02 with the XHP35HI has one of the most beautiful thrower tints I’ve ever seen. The XHP35 HI in that light on turbo measures:

CCT: 4378K
DUV: –0.0025
Ra (CRI): 72.5
R9: –22.1
Rf: 70
Rg: 95

I don’t own the GT but I seen pics of it and the tint should be about the same. Any idea where to get these rosy tinted XHP35HI?

Edit: I just measured my MT09R modded by TA with w/ (1) 80cri C4 bin 4500k & (2) 80cri C2 bin 4000k
CCT: 4829K
DUV: –0.0003
Ra (CRI): 80.5
R9: 5.1
Rf: 79
Rg: 97

I’m thinking TA might have put in a 5000K in stead of the 4000K but who knows maybe the reflector increased the color temp. The tint is in this mixed tint light is pretty much exactly on the BBL, which is nice but I like the warmer and rosier tint in the MF02 better.

The 45E and 40E emitters I’ve used have been quite neutral visually - pretty much on the blackbody line by my estimation.

That looks nice!

I wounder why it has not Emisar in its name.

WOW! What a great looking flashlight. Will there be a 5700K tint? Most people like the warner tints and not sure why. Maybe its my eyes but anything below 5000K looks dull like my X7 Marauder I got last year and it’s been sitting in the safe since then. 6500K is to high and just to much glare. 5700k is perfect in my opinion. Maybe the 25+ years of welding has taken its tole on my old viewers. I accidently ordered a D4S V2 in 5000K last week, Thank you Hank! Hope it’s not like my D4 where everything has a yellow tint to it. I gave away my Imalent DN35 and DN70 flashlights because they had that same dull yellowish tint. Different strokes for different folks I guess.

Emisar brand is for direct-drive, Noctigon is for regulated/boost/CC

I think most people tend to like about 4000K-5000K, which overlaps with the color temperature of direct sunlight for most of the day. Sometimes it’s lower at sunset, and in summer or in the tropics at midday, it can be a little higher. It’s mostly subjective preference.

For a thrower like this, there’s an objective reason to go warmer: backscatter. Warmer tints produce less visible backscatter, so you see more of what you’re illuminating and less of the beam.

I have to agree with you and eat lots of words lol :person_facepalming: My brand new Acebeam X45 came with the XHP70.2 P2 6500k emitters and it just ignites every particle in the air causing a white out affect if its not a clear clean night. I have to hold the flashlight above my head, those 18000 lumens are blinding.

That really is a great looking flashlight! Can not wait to get my hands on one.

Now consider that’s only 109 kcd. The K1 will be as much as 600 kcd.

The backscatter might not be as blinding with fewer lumens, but cool tints at that kind of intensity make beams that look almost solid. Good for looking cool; less good for seeing things.

Respectfully disagree about the tint difference, I have beam shots of two GT’s, one in warm white and one in cool white, illuminating a water tower in a light rain at 1.9 miles. The cool white is brighter and lights up the tower better in spite of the rain… and I had my wife shining the lights while I went closer to the tower for pictures of the illumination factor. With me 600 yds from the tower the cool white showed brighter and clearer and the pictures clearly showed it.

Fog lights work to undercut heavy fog because they have a flat beam that is focused close to the car. The Amber color is more to not distract oncoming drivers than anything… point them up for distance like your headlights and you will still see a wall of fog, just a different color wall.

The primary reason we see a difference between warm and cool is that the warm emitters are lower powered, thus they illuminate fog or smoke less than a higher powered cool white beam. This is my take on the ~1000 lights I’ve built. YMMV

This will always be an argument because we all see slightly differently, we all use lights to our own advantage as compared to how others use them, so just remember that any advise, including mine, is more relevant to that opinion than to what YOU might do with a flashlight. :wink:

I personally would love the White Flat in the new K1 but it’s pencil beam is not as desirable as a broader more powerful beam so I will go with the XHP-35 HI. Of course I have a lot of lights so slotting a new one between what I have is becoming more difficult. :smiley:

Dale, take those pictures from right behind or barely to the side of the light and the visibility difference will be very obvious.

Rayleigh scattering and interaction of water with different wavelengths of light are things that exist.

Whether a warm white emitter gets more light downrange due to less scattering/absorption vs the higher output of cool white is one issue, but it’s undeniable that cool white lights cause WAY more backscatter than the usual 10-15% output advantage would suggest and we have the science that explains why.

Cameras don’t function exactly like human eye does in many ways either, so while those pictures might be accurately showing what the human eye would see, they also might not be.
