Thanks Clemence! And I noticed that the 219B sw45k has no voltage rank too.

[clemence]

All of them

Got me some 2000K 90CRI 21A’s for some winter modding . Great effort Clemence! :+1:

Unfortunately the sm653 9080 E21A isn’t there yet.
I bet you’re going to make another cuddling mode flashlight. The output of sm203 9050 E21A only topped at D180. And Nichia couldn’t guarantee the availability of D180. These reel is a mix of D160 and D180 according the the PO. Hopefully you don’t get too much variations. I hope the variation would be gradual between LEDS next to each other.

Hi clemence,

Would it be possible for you to re-upload the pics in the OP? Almost every picture in the OP is no longer available. Thanks.

Already fix some. Will do the rest (hopefully) after finished with packing tonight

E21A CCT & tint shots:

With faceted TIR lens, the 4 LED’s was very well mixed

The quadtrix under spherical lens. It’s just a bad aspheric lens from a cheap zoomie pull, please don’t complain about the beam.

what is “ALL” ?

[clemence]

@Jerommel

what is “ALL” ?

sm203 + sm303 + sm403 + sm503 all at once
Check this thread: New VirEnce MCPCB for E17/E21/119/144/233U

[Jerommel]

Aha, i see.

@clemence

There really is a sm503 R9080 clemence? (2nd from the right)

[clemence]

Yes, sm303 and sm503 R9080 have been in the store for almost a year. You can also check my “herbal” tint shot

I was thinking of the 219B/C variety, hahaha, sorry. It’s available in the store all right, https://www.virence.com/blank-rwrlr/nvswe21at.

Those E21 Nichias, I understand that dedicated boards are on their way, but I wonder if these LEDs have been used with existing boards? I am really interested in domeless high cri LEDs, the 083b being my grail at the moment.

Yes they have. Scroll up and then click this link to see almost anything you need to know about the development of the boards

New VirEnce MCPCB for E17/E21/119/144/233U

Hi guys, I'm going to make custom copper round CDTP MCPCB for a single Nichia 144A. This new board will have several features: Non insulated for superior heatsinking with direct soldering OR Insulated with options to use either thermal adhesives or pad High reflectance white masking ink High temperature masking ink (lead free/direct soldering friendly - less yellowing) Hopefully will performs same or better than my previous 30mm x 30mm VirEnce board (will post the test result …

Thanks for the reference! I had read that thread thoroughly. Just was wondering if those LEDs had been used in flashlights before. Maybe with the boards used for 119s?

Ah I see. I assumed you asked about existing VirEnce boards. AFAIK, I’ve never seen any flashlights made using this LED as OEM. The only flashlight I knew was Jensen567’s P60. Maybe he’ll be kind enough to share his builds to us here.

And as for the 119 boards, Djozz tested these LEDs with his 119 board. But the gap is too wide for it to work properly. You need 0,2mm gap with E21A/E17A. Nichia E17A/E21A series (April 19th: updated with output tests in the OP)

[Jensen567]

Even mine is not really a flashlight, just a beam tester. I need a 17mm boost driver to actually run it in a flashlight since I setup the emitters in 2S2P configuration. But this does at least show the quadtrix configuration gives a very nice beam without any donut hole, even just using a simple P60 OP reflector. I haven’t tried SMO but I suspect there would be a donut. I will be building lots more with E21A once I get some more components.
