Cree changed production process for XP-G2 emitters!

Alright…

Maybe Cree will not try to please us… Maybe Samsung, LG, Osram and others will look into this thread and try to please us.

I did not seen any results… Did you seen them?

Real results are lux numbers in well known hosts.

Well, with my limited understanding, looking at djozz’ tests, it looks like the closest is Nichia 219C. Maybe you can convince your customers that even though there is some loss of throw, they get much nicer tint and color rendering index from a Nichia. And, since the 219C is still new, there’s probably plenty of room for Nichia to continue improving its performance.

We also still have left to see the performance of the new XP-G3. Maybe Cree will be redeemed in your eyes with this one? I’m looking forward to seeing how it performs.

Sorry, but I doubt that as well. Flashlights are probably less than 1% of the market for these LEDs, and flashlight modification like you do is probably less than 1% of the flashlight market. It would be a terrible business decision to spend money developing products just to meet our desires. We just have to hope that the greater market’s desires fall in line with our own. Luckily that seems like it might be happening with Cree’s HI variants

Well, he was only testing three specific claims: The de-domed tint is green, the Vf is higher, the Die is larger. He told us his results in those areas. The tint was not green to the eyes of his testers, the Vf is actually lower, and the die is confirmed to be a little bigger. He only tested one of each LED ( old and new XP-G2 ).

RMM does use LED Seal, maybe that makes a difference as to why his aren’t green?

Exactly…

He used some kind of lacquer on emitter surface… I will tell to RMM that I also know how to do that but that is not real test…

Real test is pure de domed emitter and not lacquered one. Why?

Cause lacquer changes tint to cooler one

Vinz did that long time ago with “diamond treating” method

So look how 2 same emitters behave when one is “diamond treated” :slight_smile:

And even that won’t change anything! Emitter (XP-G2 S4 2B) will still have significantly les lux performance.

RMM didn’t mention anything about lux, except to say that if the lumens are the same then the lux will be lower because he confirmed the die is bigger. You can’t find issue with a claim he didn’t even try to make.

He was addressing Vf and tint shift (not lux specifically), and you still wrote off his findings.

If dislike the tint so much, use LED seal to fix it. Then find some other solution to your lux problems.

Are you RMM’s lawyer?

His findings are already tested by Djozz (did you even read this thread? ),

So if he entered the thread claiming that there is no tint shift to green one although 20 of us had this issue then I have every right to suspect cause I did test with 20 of them in 2 different hosts. What test can be better than mine test? Tell me…

And I told him that he uses lacquer and that he has tint shift.

So RMM if you are looking this do test without lacquer and then you’ll see that LI is right. Angry Hulk will strike… I assure you.

Edit:
Pilotdog…

My lux problems? We will all have damn lux problems. Don’t address this as exclusively mine problem cause tomorrow you’ll have same problem.

RMM is a lawyer, so he wouldn’t need me anyways. Don’t be ridiculous. I’m just getting tired of the off-base arguments in this thread.

So you agree that the sealant RMM used solved the tint issue for him? Great, then maybe you should also use the sealant to solve the tint issue.

I am trying to help resolve some of your problems, instead of just complaining about a situation you don’t, and won’t ever have control of.

I know the lux dropped, it sucks, but I can’t do anything about how cree changes things, so I’m moving on.

But you guys should direct arguments towards Cree and not toward me.

This whole thing is proven fact.

There is no help or cure for this… Only new emitters or old stock XP-G2 S4 2B one.

Edit:

But we can if we all hold together and if someone(owner or co owner of this forum) writes a note to Cree with reference to this thread.

They are familiar with old production process of G2 emitters so they really can make things better for us.

And THIS attitude is really your biggest roadblock right now. When you think your only hope is to go back to something that no longer exists, then you become utterly hopeless. Change your thinking. Start looking for a way forward, because none of us can make Cree change anything. They have done what they did because it was an improvement by their standards. Start looking at other emitters and other processes and try to figure out how to flow with technology changes instead of against. Companies that try to flow against market changes usually don’t survive long. People who resist change become bitter and useless as the whole world passes them by.

Cree didn’t make a change for no reason, there must have been a very good business reason for the change. As such, the threat of losing a few thousand dollars total from this forum in the next couple of years will make no difference to them, no matter how many people on this little forum complain about it.

I’ve said all I can say about it, as have others. If you want to keep hoping for change from Cree, go for it. The only way I can see it changing is if the difference was just a manufacturing error that didn’t get caught in QC and future batches (if they continue the 2 now that 3 is here) will be back to the old way. So you can hope for that.

Ok,

Cree made really good thing by changing production process for XP-G2 emitters

Actually from their point of view I’m sure they did. Without a doubt it wasn’t something they did lightly. The impact of blf users doesn’t even rise to the background noise level for them.

Hello

I just happened the same :rage: the same leds of the same store (IO)
After dedome turned very very warm tone :confounded: naked eye the phosfor also change to a very yellow tone, low kcds, and low Amp :person_facepalming:

Perhaps I pull my money?

It isn’t Hank’s (IO) fault , as the title says “Cree changed production….” .
I don’t say these new xp-g2’s are good , but pulling your money will only cause Hank to pay them from his wallet .

Gaston,

I had same situation.

I was very angry and I did contact Hank explaining him the problem…

Hank is really not fault but he could reply in this thread and offer his advice or opinion.

And as plenty of guys here stated (please read posts on page before this one) Cree only wants all the best for their costumers so we must withstand everything they throw at us cause Budget Light Forum is to small community, and Cree does not care for us.

I accepted that and now i feel great. :beer:

I am currently quit with modding… I am waiting for emitter that is worthy replacement of good old XP-G2 S4 2B (R.I.P.) and hopefully I’ll start with modding again.

Cutter samples are on its way to me, keep your fingers crossed

Ok Mitko,

Mitko , any clue if the emitters(in triples) from kaidomain are the “old” batch ?
