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

That’s not the problem.

It’s more about costs. 10 LEDs will cost way more individually rather than 300 LEDs, and shipping is even more expensive.

But I agree. If people want to order LEDs alone, they can.

Shipping starts at $5 for US domestic but yes I can see how people outside the US would need to arrange more LEDs to get reasonable shipping.

Shipping from the US to the EU is a huge cost factor. Especially for small orders it is 99% of the time not economic.
As example.
For some time now i am searching for a chep source for Nyogel 760. The cheapest option i found is to buy a 3oz tube of XG12 from Motocraft (if you check the datasheet you will find that it is repackaged Nyogel 760).
In the US you pay ~11$+ a few bucks for shipping.
Here i pay ~30-40€ inkl shipping. And shipping from the US + item price is 99% of the time above the tax free threshold. So you can add another 19% ontop of everything.

So be able to get a better price (because of GB orders) and to get relative cheap shipping is very nice!
Big thanks to BlueSwordM and everybody that helps to organize GroupBuys and similar things!

Any updates on shipping of the 3500K's?

No, not really.

I should be home on Monday, but I probably won’t receive the package until Thursday/Wednesday.

I did not follow this thread for a while, thought it was just about springs of which I have sufficient.

But are there any “early” 3500K SST-20’s unspoken for?

There should be, but I’m not exactly sure.

Will check when I come home tomorrow.

:+1: thanks

Excellent. Will send a PM to both you and djozz.

Prepared all of the orders, and will ship tomorrow.

Will reflow the SST-20 in my EDC TK15 to see how much throw and how much better the tint is :slight_smile:

Hank's (IOS) D4S listing page is a great reference to compare how the various LED's do in a real flashlight, though it's using just TIR optics:

https://intl-outdoor.com/emisar-d4s-26650-high-power-led-flashlight-p-932.html

  • The 95+ CRI SST-20's seem to do about the same throw as XP-G2 S4's, little lower in lumens, nice upgrade in throw and CRI bump from 219C's
  • The 5000K SST-20 seems like a great compromise of excellent throw, lumens, and tint, if the lower CRI and tint is ok for you

Of course this depends on bins of the LED's used... Also what's missing is the amps these are pulling. You would assume the XP-G2's and XPL's would pull less amps.

Hi
SST-20 3000k and 4000k available ?

Please read the opening post, down there, it's accessible.


By the way, who else is noticing thread auto-subscriptions upon revisit to take a peek?

^:)

So, finally did the tests with the 3500k SST-20 vs the LH351D 4000k.

Picture of die size comparison

Tint comparison with SST-20 3500k and LH351D 4000k on similar reflectors at 1 amp.

And by god is the 4000k LH351D green compared to the 3500k GA3 SST-20!

I also got a significant throw increase by swapping in the SST-20 in my Thorfire TK15, and a nice increase in red color rendition, probably given by the lower CCT and lower duv. It’s a pure 3500k tint at 1 amp.

Nice! Thanx!!

I don't notice the green much in the LH351D's, but comparatively it could be lot more obvious. Also I got mine from Richard at MtnE - it's a P6 bin but that's all I know bout the tint.
