How is it going with the LH351D 4000K dream bin group buy? Will there be also a second group buy for SST20 FD2 leds?

Sorry if I didn’t respond.

I came back from Florida Saturday, and had to go to the hospital because of me falling off of an e-bike, getting seriously hurt.

Nothing bad came out of it though, so I’m back!
Recovery is relatively quick, so I’m feeling much better now.

@Skylight,

1. It will be delayed, but it’s still up.

2. Yes, there will be a second SST-20 GB.

Of course.

Shipping issues have been resolved on my part, but not on Croatia Post’s part yet.

Still, I wonder why it was able to get through you the 1st time, but not the 2nd time.

Maybe I should just send a postcard to see what happens next.

Don’t give up.

It might just have been just an issue once.

I’m willing to bet everything will be fine now.

Good to hear you are feeling better. Good recovery!

Thank you for answering my questions. It is not urgent, but I always have good use for high CRI leds.

Will you have also the below BBL 3000K or 3500K SST20’s?

3000k, yes. Same color tint bin as before.

I’ll have to confirm for the 3500k.

Dang if we can get the same flux and chromaticity bin for the 3000k and 3500k that would be nice. I’m keen to pick up a couple.

Was it confirmed that all 3500k emitters shipping out for the 2nd GB were J4 Flux, GA3 chromaticity bins?

… impossible. Same chromaticity bin is impossible, this is because a chromaticity bin also defines its CCT. If you mean CCT off-axis equivalent, then that is possible, the first letter in the chromaticity bin defines CCT. So GA3 is 3500K, A3 chromaticity rhombus, and HA3 is 3000K and same rhombus of coordinates.

Concerning same flux, that is unlikely. This has to do with the way lumens and luminous efficacy is defined. Led emitters with the same radiant flux bin do their job equally well, but if rated in lumens, which is defined over an average human mind-eye bias, emitters with CCT curves which contain a higher amount of light to which the average human is more sensitive will look brighter. It's the way it is. ¯\_(ツ)_/¯

Hey Blue,

Would you be willing to sell the large springs separately? After my last order it sounded like you would rather not do that since they’re a pair. I just rarely need dual springs.

I’m using the large ones a lot for the Convoy C8+ lights and others similar. I also stopped installing them into the Sofirn C8F because dual springs made it too stiff with how tight fit a 21700 was. I was thinking it might start to dent in the positive contact.

Finally created my own website to sell on so that’s all going well

Of course I can sell them separately, no problem there

I understand your situation, like you mentioned last time.

@Barkuti, I was referencing compared to the last GB.

Getting the HD2 3000k SST-20 was easier than finding a source for GA3 SST-20 3500k.

Awesome, thank you. I’ll send you a pm when I’ve decided how many I need.

Do you get them made in China? Would it at all be possible to get a bulk lot shipped direct and I just pay you? If it’s some crazy number you have to order at once then that wouldn’t work. Max would be 1000

Currently I’ve been offering these springs as an upgrade at a cost but thinking it would be better to install them in everything. If I advertise with better springs it would sound better then mentioning the stock bypass possibly breaking.

2500 would be the threshold to get the same price as I did.

I still have a lot of springs though, so 1000 should not be a problem.

I’ll just have to count 1000 of them, and check if everything is ok.

I always have a 100 spring margin, so that’s not a problem.

And yes, I do get them made in China.

Let’s speak somewhere else though.

Ahaha I worded my original comment pretty poorly. Thanks for clarifying though. By “same” I was referring to the same flux and chromaticity bins that were offered for each respective emitter in the 2nd group buy that ran previously, hosted by Bluesword.

For reference, the following options were offered in the previous GB:
3500k: J4 Flux bin, GA3 tint bin
3000k: J2 Flux bin, HD2/HA4 tint bin

@Lund1660, sent you a PM. Strange that you did not receive it yet. I know that my reshipped packages have been delayed by Canada Post because of Black Friday and Cyber Monday, but other people did not have this problem.

Did not receive a message from Canada Post, so not worried just yet.

@0oklight, sorry. My springs will fit inside of an ROT66, but not work, as they are too tall.

You’ll want 4pcs large and 4pcs small for a dual setup.
