Hey all is my first post here and it looks like the main photo and a couple other photos below are not in the correct orientation.
I just got some new parts in to build a couple of throwy FW1A with aux (still waiting for the aux boards from OshPark). I got several different aspheric lenses, TIR optics that have been recommended in the past and the round-die Yinding 5050 emitter in 3000k (See the Opple 3 data below).
Still got some work to do as I need to work out which aspheric to use and the correct focal length which gives the most throw. After that I need to design a 3D printed spacer for the aspheric to sit on.
Edit: I like this emitter already, throwy (small emitting surface), warm (3000k), rosy (duv -0.0025!), and CRI not that bad! It is supposed to take up to around 8A of current I think.
How did you manage to pull a negative duv Yinding?? Every one I have seen is sickening. Good on you!!
From reading the Yinding thread over at BLF, there seems to be quite a large variation in tint measurements, both positive and negative duv. Someone measured a duv of -0.0067, so I guess I won the tint lottery.
