New Aspheric/Optic/Emitter Day, Yinding 5050 3000k for the FW1A

3 years ago by zumlin to c/flashlight

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.

@TacGriz I saw that you were looking for a throwy TIR for your FW1A, how about an aspheric lens? My mod is in progress but I think it looks quite promising. From preliminary testing, the beam is nice and round with the round-die emitter. But the emitter is magnified so clearly such that the uneveness in the phosphor can be seen on a white wall. Though it won't be seen when used as a thrower in real life.

When we all realized the FW series was going the way of the Dodo, I snatched up a FW1A. I bought it purely for modding like @TacGriz did to SFT40 but I keep seeing these emitters and think that's what I will go with. Excited to see what you settle on.

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.
