I have no plan for that. For the next several months it will be MCPCB first, LED later. Too many E21A piling up at the moment. I’m also trying to beat Samsung’s COB in a city hall garden project with E21A. Losing three months already.

Without having joined the discussion about them, I just bought 7 of the 4070e leds because I think that the tint is really good.

If one of the initiators requesting this led miss out because of me, I will kindly ask Clemence to cancel my order

934

I put an order in for 6 of them to try out.

935

Got the 8pcs and looking forward to these. After this batch, it doesn’t look like they’ll be available for a while

936

What is special / new on these emitters comparing to oter 219C R9050?

937

938

In other words: they are binned in a different way than before (this was new for Nichia, right?) in this case a segment that is completely below the BBL.
Individual SW403 leds may have the same tint as individual SW4070e leds because there is some overlap. But these may contain very rosy leds too.

939

Correct Jos, except for the SW (ANSI binning). Only 219B and few other COB Nichias still use ANSI binning, the rest are all using Macadam’s binning (SM).
There’s still lottery involved unless Nichia uses zero steps Macadam :laughing: . With sm4070e at least everything will be below BBL (better warranty for green haters)

940

Down with Green.

Are the 219C sm4070e all gone?
I can’t find them in the shop.

I can’t find any shipping costs on the website.

You have to select the tint from the menu on the 219C page. It’s there.

945

You have to select the “CCT & bin” from the pull down menu first

Hey Clemence,

Just wanted to say i put a Nichia NVSLE21AT sm403-D200-M1-R9080 in a K03 with a pebbled TIR running around 2.5 Watts and it’s just gorgeous. :heart_eyes:

947

Picture please :partying_face:

948

Maybe later.

But i have a question that may already have been asked and answered:

Any hope for high a CRI 319A ?

949

What mcpcb did you use? That light says it comes with an XP. Can that board be made to work with those little emitters?

950

No, that’s not gonna work.
You need either an XQ board or (like i did) use a “Djozz board”.

951

Thanks, that’s what I thought. So where did you get the board?
