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.

I think it is a good choice, even if you just use the crappy reflector from the FW1A Pro. I played around with that reflector very briefly and just raising that reflector a little bit will tighten up the beam from the Yinding.

I just need to have aux though, so I won't be using a reflector.
