Second Generation Silver Plated High Current Beryllium Copper Springs and 95+CRI SST20!

No problem.

The only thing would be that the J4 flux bin is more prone to getting an above BBL line tint bin, being GA3,GB4,GC1,GD2, having a 50% chance of getting one above the BBL.

The J3 flux bin has been confirmed by the rep last time to be GA3/GA4 depending on the quantity ordered.

Same thing for the J2 flux bin of the 3000k version, being confirmed HD2/HA4 depending on the quantity ordered.

I rather get the GA4 with J3 than random tint bin with J4.

However, Emisar was able to get J4 flux bin and HD2 tint bin. Wonder where they bought it from.

Well, they probably have a special relation with their supplier since they can easily buy 10000s of LEDs at a time, so they can get more choice in term of chromacity bin order code.

I’m not willing to take the risk of a J4402 chromacity bin getting an above tint bin, even with a higher flux bin.

The only way I would be willing to take a risk would be that some people here pay for the order, and then I order it myself to see what happens.

If the tint bin is good, I’ll sell it normally.

If not, I’ll just sell it for cost.

Don’t forget - if you do CCT mixing, you get a lower tint. So, even two emitters with a “green” tint (above BBL), if they are far enough away from each other in CCT, can make a “mixed” CCT that has a “rosy” tint (below BBL). :wink:

I know this doesn’t help in single emitter or otherwise single CCT builds, but it’s a thought. :innocent:

I’m thinking about a very small quantity of each, but not ready to confirm. Is there a planned cutoff date?

Also, are you still considering an LH351D order?

Yes of course. The only tint available for the LH351Ds are T6 bins, so about as good as the AEDe groupbuy LEDs. I’m still currently searching for a source.

I’ve currently found a contact at Future Electronics which may be able to pick up some good tinted LH351Ds.

HOWEVER, I can easily buy the springs, and ship them quickly, compared to the lead time of the LEDs.

So springs are the priority.

Too far away CCT mixes can and usually will screw up the CRI, although it may not matter much (if at all) depending on user preferences. To avoid too much CRI loss I get along with a maximum of 1 to 1.5K CCT distance when mixing high CRI emitter dyads. Some testing in this regard would be nice to see (CCT emitter delta vs CRI loss), but we need to convince some tester about this. maukka has a nice deal of high CRI emitters… O:)

Cheers ^:)

Please write me to 20 big and 10 small spring. Thanks :slight_smile:

Added to the list.

Not really.

I’m interested in some 4000K SST-20s if you can secure a batch below the BBL.

@BlueSwordM, I didn’t see my name on the list. Can you add me? Thanks!

Already added, don’t worry.

I just have to find a way to screenshot my massive spreadsheet.

Can I add 15x SST-20 3000k 95CRI?
Thank you

Springs received. Fine . Thank you.

I’d like 15 large and 15 small springs, thanks :slight_smile:

If its not too late, can I update my order to the following:

8x SST-20 4000K
4x SST-20 3500K
2x SST-20 3000K
2x LH351D 4000K

Thanks

@johnkey68, excellent. Hope you like them :slight_smile:

All added to the list.

We are at

1390 large springs
1360 small springs
269 SST-20 4000k 95CRI
141 SST-20 3500k 95CRI
75 SST-20 3000k 95CRI
217 LH351D 4000k 90CRI

It’s probably normal but as I am now working with the springs, I noticed that the small spring (from the previous gb of course) remains shorter when compressed the first time?

Yes, with these springs, both small and large, it is normal for it to stay somewhat compressed permanently from the first use. The new ones will be the same too. It shouldn’t get any worse though. Once that little bit of length is lost the first time, that should be all.
