ThorFire C8 2×2 Mod.


  • One Thorfire C8s
  • Four warm white XP-G2 of unknown flux binning…
  • Mounted in a 2×2 array on a direct thermal path copper MCPCB which electrically connected them in parallel
  • DCfix diffusion film
  • Lexel’s 17mm version of the TA v1 driver.

For my first pass, I used an orange peel reflector I had on hand in the hope that it would, on its own, blend the beam enough to eliminate a dark spot in the center caused by the gaps between the emitters.

When that didn’t work, I used some diffusion film, which worked really well, well enough that I decided to try the original reflector. The film was still enough to blend the beam enough to remove the dark spot in the center of the beam.

The end result is bright and quite floody. I don’t have a great way to measure the brightess or intesity, but I’d guess that its less bright than my BLF Q8 and brighter than the 3x Nichia 319a emiters I put into a Sofirn C8F

I still have more of the MCPCBs, I’d like to try another build, but I’m not sue what emitters to use. I want more power, and also higher CRI.
