I ordered some of these from KD and I plan to make a high CRI D4. This will be my first high CRI light.
I don’t have a strong opinion regarding the greenness or rosiness of a tint, but I’m looking forward to seeing the color rendering advantages. The only time I’ve really noticed bad color rendering is with cree 1A cool tint that seems to not have enough red-like colors.
Thanks for the feedback and additional input!
Excited to try these SST20’s out.
This is my first triple, with a Convoy S2+ Desert Tan host, MTN FET+7135 Driver, triple SST-20 4000K and a Carclo 10507.
The coloring rendering ability of these emitters are excellent, but when comparing it side by side with my friend’s 219B SW40 R8000, my tint appears to be yellow, and of course, his tint is noticeably rosier. I’m not sure how much my AR-coated lens affect the tint, it’s the type of coating with some sort of red reflection rather then the more common purple/ blue one. I tried comparing the tints with and without the AR-coated lens, but I hardly notice any difference.
How are you doing with SST-20 dedoming?
I recently tried razor blade dedoming over turpentine bathed emitters (dome softening up) and it seems to work well. The turpentine bath did not do much on an old XM-L first generation softening up wise, it was done for 2 to 3 days but at refrigerator temp (I like the smell of turpentine in my fridge :-D LoL).
Cheers ^:)
I got a supposed FA1 tint bin from TA and it ended up being very similar to the FB4 tested in the OP. Actually a bit worse…
TA?
Thanks for the test. I’m looking forward to the day a nice tint bin is available for this emitter.
In case anyone’s interested, led4power has it in FC1 bin.
I have some of these FC1 and unfortunately the hulk-factor is strong with this one. With high currents they are fine, but low currents are terrible
Every SST I’ve tried has some hulk in them 
My SST-20s(FB4) also have some hulk factor at lower currents, and at higher currents the beam is noticeably yellow through the Carclo 10507. I feel like 319A gives a cleaner light and 219C is only slightly green?
the 3000K and 3500K aren’t green but they are slightly yellow sometimes and quite a bit lower flux bin
Higher duv is green on higher CCTs and yellow on lower CCTs. Same thing.
what would the ugly child of 3000k + 4000k, both slightly high duv look like?
But seriously, it could be nicely ending up on top of the BBL 
Something like this? :laughing:
I guess I’ll have to try and see it myself
I wonder how came this emitter was so highly rated initially. Did worse batches hit the market? Or did we not understand it enough?
Does dedoming improve tint significantly? I ask partially because I’ve seen a mention of SFT-20-W on Luminus website and in several other places….this would be SST-20 but flat from the factory.
It might become better.
I think the negative comments on the SST-20 are in comparison to other emitters that have GREAT tint. When compared to other Cree emitters or recent 219C 5000K it is still pretty nice.
I think I have lights with 3000K 3500K and 4000K. I could try mixing them by just shining on a wall but problem is they are different output and reflector/tir.
If I recall the 3500K looks fairly good on its own (from Mouser / BlueSword) so if you haven’t purchased emitters yet I would suggest trying that over buying 2 emitters you know you dont like.
Shaving the dome off with a razor (not a very clean job), the tint got noticeably better.
