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

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.

Thnx David.

Yeah, it’s more of a problem with the smaller spring compared to the larger one, because the wire thickness/spring diameter ratio is lower than the big spring, meaning more room for deformation.

Therefore, it will deform it more compared to the large spring in terms of %.

The small springs I've used in a coupe of lights are pretty stiff, stiffer than most stock springs. Maybe good for some mods, and for others may make it harder to thread on a tailcap - I'm having some of that trouble on a couple mods. Was debating cutting the spring down, but getting it all flat may be a challenge for me. Shame because I've decided against using them in some lights. I'd assume if I try cutting then grinding flat, I'd be taking off a fair amount of the conductive coating, or is the full spring conductive to the core?

Just cut the spring down. I’ve done it myself, and it does nothing to conductivity even if not flat.

DO NOT GRIND THEM DOWN. The worry is not conductivity, but BERYLLIUM COPPER DUST.

In any circumstance, do not grind them down. Beryllium Copper dust from grinding is dangerous.

One thing you can do to make them less stiff is just to compress it manually. It will plastically deform, and will make it permanently smaller.

Do you cut the top or bottom? Bottom makes it harder to get flat/even? Top would tend to scratch the batts?

Not even sanding? I'm old anyways, 20-30 year effects don't matter to me...

Cut to the top. Nickel is softer than steel, so unlike uncoated steel springs, it will not scratch the steel casing of the batteries.

I have cut several of the smaller springs to make more room also, mainly in the SWM V11R. I cut the top as blue did.
Its not easy once cut to get a neat looking top but its very doable.
I usually bend the cut end down slightly and file the tip of the cut to get rid of any sharp edges.
Then squeeze the top loop slightly smaller than the next loop down. Works great, no complaints.
