I received the early bird SST-20s a couple days ago and stuck them in a few lights. In a D1S I get 670 lumens and 550m throw compared to 1000 lumens and 670m stock. There seems to be a tendency towards a ring around the corona with smooth reflectors, though it’s a lot more prominent in the Convoy C8. The tint isn’t horrible but it’s not spectacular either. This is an sw35 219B beside the 3500K SST-20 in the D1S.
Got mine today! Just opened them a min ago, well taped up. I should first put one in a D1 because my attempt at a sliced SST-40 in there didn't work out so well. Also got couple C8F hosts, so these will go in one for sure, then something smaller, not sure yet.
Final specs have not been finalized for the large spring yet.
I’ve already tried this for the small spring last time, but did not work theoretically, and the manufacturer advised against doing this too for the small spring.
It should work with a 12mm height, but I’m waiting for a response from the manufacturer.
Thank you for publishing the list. Could you please reduce the SST20 4000K for me (line 5) to 20 pieces? And please add 20 small NICKEL-plated springs. My flashlights are really looking forward to get some high quality springs!
