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?

107

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 ^:)

109

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

110

Added to the list.

111

Not really.

112

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

113

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

114

Already added, don’t worry.

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

115

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

116

Springs received. Fine . Thank you.

117

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

118

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

119

@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?

121

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.

122

Thnx David.

123

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 %.

124

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?

125

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.
