Not posted on the no discussion thread but these sofirnlight prices seem good enough to point out. Screen capture from my order:

I previously ordered a Q8 driver for another project for $7.81 but found a Q8 driver from Lexel I haven’t used so $11.99 for the host + $7.81 for the driver = $19.80 ready for mcpcb with my choice of emitters. sst-40, lh351d, luxeon mz… hard to decide. Not that I need another Q8 since I also ordered the anduril version they have listed for $39.99…

edit2: ordered mcpcbs from led4power - one bare for lh351d from intl-outdoor ond one with luxeon mz. It’ll be interesting to see how they compare to the original BLF Q8.
