Dedomed LED Tints Compared: XP-G3, XP-G2, XP-L

Thanks MEM. Nice work.

Thanks MEM!

Nice beam comparison, that was a lot of work! I recognize the beam of the XP-G3, it looks very much like the beam of the Luxeon Q that has the same build.

The OP would however gain completeness and significance if each beam was given with the luxnumber of the hotspot. You are almost there: same host and battery configuration over all emitters and a standard set-up at 5 meter, just get yourself a (mid-quality) luxmeter and do the measurement. :slight_smile:

+1 I was thinking this, but didnā€™t want to be the one who said it! Luminarium would have his direct comparison then and weā€™d all know how these emitters actually line up against each other!

Nice photo.
What kind of white balance setting? XP-L HI is too much blue tint than I expected.
I took a photo for stock XP-L dedome. And that is too much greenish color. So I sold it.
However your photoā€™s stock XP-L DD seems like nice tint.

So I wonder your white balance.

Hi MEM. Very nice. Thanks :wink: Do you maybe have lux figures?

Edit: I see youā€™ve listed some figures here. I see you mention that thereā€™s a factory DD XP-G2 version. In the current post you mention that the XP-G2 S2 1A is non-stockā€¦

How does the stock vs non-stock XP-G2 lux figures differ? Do you know the spec, including bin, of the stock DD XP-G2?

Hey fenno. Take it easyā€¦ By the way, watch your mouth, not really acceptable in this forum :wink:

Impressive work here MEM! Now I like you even more :slight_smile:

Of course lux results will be appreciated.

But about that XP-G2 work it is really necessary to determine weather you have old or new production process emitter cause new production process(since several month ago) had influence on all emitter binsā€¦ Not just on xp-g2 s4 2b

If I may add XP-G2 looks more intensive to my eyes.

Best Regards

Hey fenno, it is not that you can demand that, is a lot of effort and MEM or anyone else over here is not payed for what they build, measure and post.

No one will stop you if you measure the luxvalues yourself, and if you do, please do post them at BLF. :slight_smile:

:person_facepalming: :confounded:

Anyways thanks for posting MEM. Iā€™m a little surprised by the tint circle on the G3 as well. I thought the blanket of phosphor would have the opposite effect.

Wow, what an impressive array of comparative lights and beam shots. Thank you very much for this great contribution.

Thank you for taking all these photos MEM.

Not knowing much about photography myself, could you explain why the beamshots look bluer the faster the exposure is?

Cheers :beer:

Nice work!

Looks like the DD XP-G2 is still on top for beam intensity there (and seems to be a very neutral-tint after de-doming).
The DD XP-L V6 3D looks nice as well, and probably a good mix of throw/flood. The DD XP-G3 does look a bit disappointing though. A bit too much yellow/green tint-shift and a blue/UV corona. Maybe that one was just a bad draw of the de-dome ā€œtint lotteryā€?

Thanks for all your work mem!

I do have a lux meter. Itā€™s sort of in a, not exactly permanent, but another location than where I took these. This was more of a test of tint comparison and beam profile.

The white balance was on incandescent. I thought the 1/320 images were remarkably close to what I sawā€”in person I didnā€™t think the stock XPL was so green in this test, so it looked realistic, but I agree that the XPL HI looks very blue. On the other hand, focus an XPL HI 1A behind a lens, and the surface mostly is that blue. :wink:

I said other than factory, because most people arenā€™t aware of my group buy I did to get a custom model. The LEDs are supposed to be S2 1A, and I did confirm this quite well. :wink:

XP-G3 has the hotspot/corona effect of the old Seoul S42180 High CRI emitters, wonder if thatā€™s consistent across all tint bins?

Thanks MEM, great work.

Maybe you donā€™t know but even XP-G2 S2 1A are affected by new production process. Confirmed by several members.

By judging your pictures you may have old production process XP-G2 S2 1A.

Your pictures explains a lot and thanks to Djozz and your test here we can see that XP-G3 is not improvement at allā€¦ Well at least in de domed version.

The ones that are able to get old series of XP-G2 emitters are lucky personsā€¦ It seems that you are one of them.

OK now Iā€™m at a keyboard instead of my phone, so I can elaborate a little more. :wink:

Yes. I was able to get old production XP-G2 S2 1As. Most likely from a spare bin in Chinaā€”which is probably 1000 different locations we could only hope to locate. :stuck_out_tongue: (Itā€™s also why I provided the high-res source images, showing the emitters head on to confirm emitter details.)

Things to keep in mind here;

The LEDs are being driven at a (bucked) constant current of a little over 4 amps (about 4.2 amps). What does that mean? First off, the XP-L V6s, and XP-G3 are not being driven anywhere close to max intensity. The XP-G2 however is being driven at about 4/5ths to 5/6ths of the intensity you will ever see from one in a test like this. The XP-G2 is already making most of the lumens that it can make at over 4 amps current, in other words.

With that being said, the XP-L V6s and XP-G3 are really just getting ā€œwarmed upā€ at a current of ~4A. Remember, with Djozzā€™s test, the XP-G3 hits max output at a whopping 8 amps! So if you are drawing the conclusion that itā€™s simply not as intense as the XP-G2, just remember that its volume knob is only at a 5 of 10 here. :wink:

My thoughts? I think the XP-L V6s dedomed are incredible performers for a 2mmĀ² die size. Look at the intensity the V6 has in both tints over the unknown factory bin DD XP-L with greenish tint. I too find the 3D tint of the DD V6 to be remarkably good. So the common thoughts that only a low number tint bin (0D, 1A, 1C, 1D etc) are the tints that are most acceptable for dedoming has sort of been dismissed by this very data, I would say. It was more of a stereotype than anything.

On with the XP-G3. Although this test shows a very unlikable beam profile, in nature I find it to actually be quite usable! Yes, I mean it. The yellow ghost tint around the hotspot is warm, but thereā€™s really some usable light being made there. It gives the hotspot sort of a ā€œblendingā€ ability, where itā€™s not as pronounced, but a gradient of color range is featured and I find that the whole gradient can actually be useful. Anyways, the moral here is that Iā€™m not even close to unlocking the full potential of the XP-G3 in these tests, but this just shows at alike modest-amperage values, what you can expect from them.

I will continue to add tints to this thread, also. I have plenty more willing to shine! :smiley:

If you have a dedomed tint request, post it. :wink:

Great thread. Thanks MEM.
