The H influx do look interesting. A little disappointing efficacy given the LM301B diodes but I guess they're using cheaper bins?
''They'' (Samsung) use their own top bin diodes.
The efficacy is only supassed by the Q-series because of they run cooler, I think you might have been mislead by salesmen copying the specs on the LM301B diode to their PCB
Yeah, Q-series is top dog, but expensive and same PCB design as the F-series (bendy plastic PCBs with indents for mounting)
The H inFlux are nice aluminium PCBs with holes for mounting, and around 15% cheaper per diode compared to Q-series, and you get a lot more intensity and potential than you get with the Q-series.
That would mean better potential for delivering heat to the heatsinks? I wonder if aluminum channels can do the trick or if purposemade heatsinks need to be employed.
