Have you tried email contact? The last time I was there the checkout page told the user to contact them. There is an email on their contact page. I would try contacting clemence thru the email.
I did get that message, but I’m also waiting for Clemence to fulfill an outstanding order that I paid for over a year ago, which is part of the reason I was hoping there is another source for E21A. Unfortunately it looks like there isn’t, unless I want to order and entire reel.
It looks like there is another option for extremely warm white aside from E21A’s.
A member of the flashlight reddit shared recently that Luxeon 2835N is available from Mouser in 1800K, 90 CRI. These are 2835 size, so they should be a perfect fit for Sunlike’s board:
A 2200K, 90 CRI version is also available:
The datasheet is here:
These are mid-power LED’s - binned at 65mA, max rated current 300mA for the N series (1st link) and 480mA for the HE series (2nd link). This should be fine for the LT1. Maximum current per emitter with 7 x 7135’s divided by 18 emitters would be 136 mA.
The spectral graph is on the bottom half of page 10 of the datasheet. I’m sure it’s not Sunlike level CRI, but it looks as it should - still a little light available past 450nm on the blue end of the spectrum, and lots of light at 650 nm and beyond on the red end.
These look quite promising. I’ve been really busy over the past month and have been unable to follow blf. I sent an email to LampMan yesterday and I’m waiting on a reply.
So, if I am reading correctly… I would go to his website, configure and order but not pay until instructions are emailed? Looks like maybe delivery sometime this winter?
Just to be clear, he lives in Belarus and the updates say he was arrested for speaking out about a member of Lukashenka’s regime online, so he’s currently a political prisoner like many people in that country. The latest update is his mailing address at the prison where he’s being held, so it doesn’t seem like he expects to be released any time soon.
