It took me a while but I finally completed this mod, which started out as a FW1A Pro. This is what I did:

  • FET+7+1 driver upgraded to T1616 with aux support
  • Orange, green and purple aux
  • Yinding 5050 3000k emitter (warm and rosy, CRI > 70)
  • 3D printed spacer (white PETG)
  • Aspheric lens

I am getting around 76000cd at turn on, which is very similar to what the Bean Master got with a CULPM1 and a smooth reflector. But remember this Yinding is 3000k and rosy with a duv of -0.0075, and I think this makes it very impressive.

The main reason why I used an aspheric lens is because I needed aux, and suitable TIRs are just not throwy enough. I would also like to try to put those tiny RGB aux leds between the emitter and a reflector in the future. Enjoy the photos (sorry that most of them are in the wrong orientation, I uploaded them with my phone and I don’t think they let me set the orientation)

      Thanks, and I am jealous of your pcb designing skills, I want to learn that one day.

    Holy shit dude, this build is amazing! Great work!

      Thanks man, you inspire me to do these kind of mods. And of course, it would not have been possible without the adapter you designed.

    Such a cool mod!! I hope the SFT40 3000K ends up looking this good. I don’t have it in me to do a mod this extensive.

      Thank you. I hope so too, and high CRI!

      I just saw this posted over at BLF (credits go to koef3 and Simon from Convoy).

      The tint of that sample is at or above BBL. Fingers crossed for some rosy ones when they are actually released. Though I would not use an apheric lens to make a square beam out of one. And the reflector options for 5050 LEDS in the FW1A mean that it won’t be as throwy as a CULPM1 in a smooth reflector.

    Awesome work!

    It’s hard for me to see, but does the Yingding have a tighter spot?

    • @zumlinOPEnglish

      The KR1 SFT40 still has a bit more candela. The hotspots are similar in size but the Yinding has much less spill.

    Very cool mod! I’d love to see more experiments like this with aspheric lenses.

      Thanks. This is my first time trying it and I like the tint. Have you tried the warm one before? I also got one in cool white which is quite green and disgusting.
