Slim Pickens:

I’m in for six.
Thanks for organizing this, 3500k is not a common CCT.

After using the Nichia sw35, I’ve come to really love this CCT, especially at night outdoors.

Thanks for organizing this. I would be in for 40 (not that I need that many) just to support this if you could pin down a tint bin. The 4000k sold on KD is the FB4 bin, which has some green. Even the FA3 bin used by Fireflies, which is supposed to be at or below the BBL was reported to have some green/yellow in it and requires a minus green filter to perfect. I think it would be safer to aim for GA1 and GD4 tint bin.

I love the 3000k sold at KD with HD2 tint. It is a bit yellowish at lower lumen modes but at higher outputs the tint definitely drops below the BBL for a neutral/rosy without yellow tint. It is not as rosy as the E21A 3000k though.

10pcs for me.

JaredM · 2018-12-08T04:31:37.000Z

Mark me down for 12 please.

I have both 3k and 4k and seem to believe that 3500 may just be the sweet spot for these.

Outside of Kaidomain they aren’t sold in individual bins, only the step binnings, the tightest bin available which is what this GB is for, will include GB4, GC1, GA3, GD2 tint bins. The SST-20 offers such excellent mix of CRI and great throw that it is hard to complain about even on the bins just above BBL.

I am in for 25.

I’m in for 10. Love 3500K, but so hard to find, thanks!

You can also get 3500k Oslon Square 92CRI in 5Q tint bin.

It is two tint bins below the BBL but in reality, it looks like it is on or just a bit below the BBL. It looks great but not as rosy as E21A 3000k mixed with 4000k.

djozz · 2018-12-08T10:47:26.000Z

So maybe it is not really the 5Q bin that you got? It is nice that these 3500K Squares are for sale anyway, for a good price.

I bought multiple items from that seller and they’re pretty legit so I have no doubt that it is 5Q. It’s just that often times tint bins that are shown as being below the BBL in manufacturer’s spec sheets are actually above the BBL like in the Samsung LH351D case and as reported for the SST-20 4000k FA3 tint used in Fireflies lights. It takes 2 bins below the BBL to result in a tint at or just below the BBL. I would say the Oslon 5Q is comparable in rosiness to XP-L HI 5A/5D tint and a little less rosy than XP-G2 5A/5D tint.

The Oslon Square 96CRI 2700k 6U bin is beautiful and does look like it is at or below the BBL. Seems like tint bins for 3000k and below are more reliable like the SST-20-W 3000k from KD.

Sorry, I found more interesting offer Canada based(shipping is 3 times cheaper) so
you can remove me from the list.

azhu · 2018-12-10T15:52:47.000Z

We are over a quarter of the way there! Let’s make this happen. Really want to try them 3500k

SKV89 · 2018-12-10T17:48:42.000Z

azhu, there’s another GB thread for this emitter going on in another thread. I think it would be better if you work with BlueSword on merging the quantities so better chance of a successful gb.

Thanks for pointing that out. I’ll reach out to see if we can combine efforts to make this happen.

aswang · 2018-12-11T15:00:07.000Z

Interested in 8 pcs.

I will probably get a few of each listed on BlueSword’s thread so please remove me from this gb.

Bump

Slayer1 · 2018-12-26T03:12:15.000Z

Andy, pls remove me also from this GB. Thanks.

azhu · 2019-01-17T00:43:44.000Z

Due to the lack of interest and minimum order qty not being met, I’ve decided to close this GB. Sorry guys.

djozz · 2019-01-17T13:26:01.000Z

Thanks azhu for the effort you put into this.

Most group buys on BLF I have been aware of went through, some were fast, some took ages, not many were cancelled. I believe that the BLF group buy as a phenomenon has been extremely succesful in the past years, making rare things available and helping some great flashlight developments come true.
