TK's Emisar D4 review

Thatā€™s a very strange beamshot for a 3D tint emitter. What was the white balance set to?

The 3D tint is many things, but it is not green. Some find the ~4850K tint too cold, and prefer ~4000K more. A small handful find it too warm, and prefer 5500K or 6000K. But one thing people generally agree on is that any off-white in its beam is reddishā€¦ not green.

Itā€™s the closest Cree tint to the slightly rosy high-CRI 219B emitter almost everyone loves. (and its neighbor 4A is the closest to the slightly rosy 219A tint)

Unless it was dedomed before the beamshot. That would make it warm and greenish. For example, here are some beamshots comparing a 219c 5000K (on the right) to a D4vn (on the left) which I think may have been a 3D tint before it was dedomed:
(left = D4vn, right = D4 219c 5000K)


These pictures were taken with ā€œdaylightā€ white balance.

The code is already written and working pretty well. Smoother thermal regulation is one of several dozen things I improved since D4v2. I donā€™t know if/when it will go into production though. Iā€™m pretty sure Hank doesnā€™t want new firmware every month. Even I donā€™t bother updating firmware on all my lights every month; itā€™s kind of a pain so I try to do it only rarely.

Itā€™s possible there could be a ā€˜D4 V3ā€™ with enhancements, but I donā€™t think it will happen for a while. Hank is busy with other things. However, you donā€™t have to wait; you can reflash it yourself if you want.

Hereā€™s a graph of the regulation working in a newer version. Adjustments still stop only at ramp steps, but theyā€™re done gradually to make it difficult to see, instead of all at once like in D4v2.

Even dedomed a 3D has verry little green.

I too am interested in the D7. Not so much the D1 and D1s. I find floodier lights more useful for myself.

The soupcan design is quickly becoming my favorite for around the house. Lots of light over a wider area, looooong runtimes at lower and frankly more realistic levels, harder to misplace, super-stable to talistand and they just look impressive. I think Iā€™ll appreciate the D7 with its 3 cells design. It oughta be a bit easier to handle and still have the benefits I mentioned above.

Please send pics of the D7!!! Thanks.

Samsung Note 5 WB/5000K to my eyes it is slightly yellow/warmer tint at lower output not green. :innocent:

You bet on that :person_facepalming: :smiley:
Although Iā€™m not a tint ā€œsnobā€, Iā€™m starting to pay attention to those aspects, and want to make a good choice!
This photo is better to judge the tint, I guess. As TK said, the first one seemed more to the greenish sideā€¦
Iā€™ll probably get one of these, not ā€œpureā€ neutral nor warm white!
Thanks again for the photos myflashguy :+1:

Thanks for the explanation TK :wink:
That, along with the photos and explantion and maukka informationā€¦I guess I can relate and make a decision!

Thanks again :nerd_face:

Dale they are indeed salts. Sodium and chlorine arenā€™t the cation/anion combo to make a salt. In fact, virtually any acid will react with any base to form a salt that is the combo of the negative and positive portions of both. My b.s. In Biochemistry made me post since I am almost always lost when FL modding is the topic.

Am I allowed to post a link from CPF to show a tint comparison or is it better not to do that :question:

^

You sure can. Linking to other forums is not restricted or frowned upon here.

Work D4 doing a few poses(trying that new portrait mode out on latest apple update)ā€¦ā€¦ā€¦ā€¦ok any excuse!

Thanks for the answer :wink:
I donā€™t know if this will help others to decide on the tint, but I made my final final decision based on this comparison (after the above images kindly posted by myflashguy and TKs explanation, well and after seeing the other images posted on this and other threads)

BTW, Iā€™m going for the XP-G2 S4 3D 4885K :partying_face:

Once again, thanks! :+1:

Another slightly higher output beamshot I took awhile ago just to show u that lower & higher output beamshot can sometimes look different
:partying_face:

Thanks myflashguy :wink:
Humā€¦I guess Iā€™ll love it :heart_eyes:
Already ordered, black with XPG2 S4 3D, and the 18350 tube!
I was resisting, but I couldnā€™t hold any longer :smiley:
I guess Iā€™ll have to save the rest of the money for the FW3A :money_mouth_face: (please let it have the Anduril FW!!!)

Received my green Nichia today! Ordered 7/29 and received 9/30. Better late than never!

So what differences am I supposed to notice between the 5000k Nichia D4 and my 5000k XPL-HI D4?

Mostly, the XP-L HI should be throwier and the Nichia should be floodier (and hotter). Due to having more throw and more lumens, XP-L HI should look brighter at the same levels, while Nichia should make colors look a bit better with a more consistent white beam.

Nichia has the smaller die surface so it should, by definition, have more throw than the XP-L HI. The Nichia wonā€™t make as many lumens and itā€™ll get hotter, but in the small TIRā€™s of the optic it should have a tighter (but still large) hot spot.

How much hotter is the Nichia vs the XP-l HI?

The Nichia emitter has a dome though, which makes its apparent size bigger. Itā€™s the least-throwy of the three emitter types offered in this light, slightly behind XP-G2 and well behind XP-L HI. Measurements are in the first post. :slight_smile:

ā€¦ 5 peppers vs 2 peppers?

ā€¦

I donā€™t have a way to measure and graph temperature over time, but if anyone else here does, the results would be interesting to see.

Men shave, razors annihilate domes. Throw changes. :wink:

Does the XP-L HI throw more because of die size or sheer emissions? Not apples to apples surely. At similar lumens levels I wonderā€¦.

Edit: Point in fact, My Texas Poker has had numerous emitters in itā€™s 4 1/2 years of existence. It now has the Nichia 219C at 5000K for a very good reason, the XP-L HI did not perform well in this light. The reflector, I am told, is from Dereelight but I have never been able to find it in Dereelights catalog of parts. At any rate, in this custom made light the Nichia 219 reigns supreme.
