UPDATE: I have a lead on some more sw45k but I’d probably need a minimum of 200 pcs to make the purchase worthwhile. Anyone interested in another group buy? If so, please let me know how many you’d like.
So I reflowed 3x SW30 on a MosX 3535 triple MCPCB, driven by a LD-B4 driver set to 6A max current. This is by far the best 3000K tint I’ve seen… The tint shift between low and high current is much better than the SST-20 3000K HD2 emitters. I should have ordered more SW30 emitters! Thanks azhu!
Glad you like them! It still surprises me how popular this emitter is today despite it being so very old. Most of my favorite lights still have the 219b in them.
