Ok, the agent said the tint bins are available, but Iāll have to request a special quote directly from Digikey to Samsung, for 800pcs+, and the job should be on Samsung then.
Edit: Here is the part of the transcript I got sent to my email talking about this
David (from Digikey): If there is a difference in the part number itself, we would need the correct ordering part number. Then we can request a quote from the manufacture for the exact range.
The tint bins specified T1-T7 are available to order though, with a special quote request from us to Samsung specified before.
Yeah, I realized that I was just talking about the interaction with LT in order not to ādoubleā the works or something about these LEDs!
I mean, if it is LT that will produce the light, it will be good for them to have the LEDs, but it may be cautious to put the companies in contact to deal about it! Just thinking on this
And thatās for the initiative
Not really possible, unless we use tint mixing in the FW3A with 1x4000k and 2x 5000k.
I donāt want to hype myself too much. Iāve seen what an LH351D looks like, and from the looks of it, itās a T6/T7 bin from the AEDe GB. So looking good above 1 amp, but slightly above the BBL at that level.
What I want is a rosy type T1-T2 bin, close to 4000-4300k rather than 3900-4000k. That would be amazing
BlueSwordM, well done for trying, and I hope it ends in a result.
If LT had buyers worth anything (Iām sure they do, but maybe have not been directed yet) then this would have been sorted long ago. The plaintive request from āNā for help here was a big warning sign.
But really, what is going on here ? Asleep at the wheel doesnāt begin to describe it.
The principal should liven up, get a grip, or gently say goodbye and pass it on to those who can, and want, to do it.
I donāt really get it either. Iāve mostly had to piece together the early days of the project based on what was left behind, and that bead-blasted one seems to be the oldest FW3A prototype.
At risk of quoting Clerks, āIām not even supposed to be here today!ā Or, um, I wasnāt planning on running the project, and wasnāt even involved early on. Everyone else just kinda ā¦ left. So itās all been a bit of a mess, a mystery at times.
If I understand correctly, the process is something like this:
Private forum messages get sent to everyone on the interest list.
Click the link in the message.
Order what you want through Nealās shop.
Payment is probably via Paypal, I think.
The plan is to make 50% of the lights with XP-L HI 3D, and 50% with LH351D 4000K 90CRI. But the LH351D might happen a few weeks later because nobody seems to have it in a good tint bin and itāll need to be ordered from the manufacturer.
A lot of the details are still being worked out. However, if things happen in batches, as has happened on some earlier projects, there will need to be some way of deciding who gets to order one and who has to wait. Itāll probably be the lowest numbers first, as in, the people who requested one earlier can order sooner. Thatās part of why I went through the entire thread history to properly sort and link each request, to make sure nobody is missed and theyāre in the correct order.
Thatās only the BLF list though, and I donāt know how things will be handled on TLF. If someone there could put a timestamp on each request, I could do the same on the BLF list, and they could be merged into one.
About when shipping can happen, I really donāt know. Hopefully very soon, but that depends mostly on what Neal and Lumintop can arrange, and I donāt know much about whatās going on there. Really, the rest of the process mostly depends on Neal. So I hope that will go smoother than the GT project did. He has had a year to improve his infrastructure.
Neal is handling the part acquisition, so definitely make sure youāre talking with him. Itād be helpful if Iām Ccād too, so I know whatās happening.
I dont expect even the T1-T4 bin will be much below the BBL if at all. Samsung bins are not to be trusted. Look at how far above the BBL the T6 and T7 were eventhough they were supposed to be at or below. I would be happy if the T1-T4 is at the BBL. But nevertheless thanks for your hardwork. Itās good news nonetheless
Based on the poll results, 4500K would be the most popular CCTā¦ if that type of LH351D existed. But since it doesnāt, a T1/T2 is about as close as we can get.
For my personal use though, Iāll probably be pretty happy with XP-L HI 3D. I find it really hits the spot. And Iāll probably mod one to use 219B, eventually.
On a related note, forum member Nite Shadow pinged Nichia about making more 219B emitters in the nice R9080 sw45 bin everyone loves, and it sounds like itās still possible. However, the minimum order size is 3500 pieces, the price is unknown, and the lead time is at least 3 months. So itād require a pretty serious buyer. But if we arenāt able to find a newer higher-powered LED with the same nice tint, perhaps more old ones can be sourced.
