I should have said SMD boards,(surface-mount device light-emitting diode module) . The word "quantum" has become more or less generic for this style lightJust a FYI, with no actual relevance to the topic at hand, but neither of those boards are quantum boards. HLG came up with the "quantum" board name for their lights and other manufactures using the same Samsung 301 diodes are simply using the name to steal market share. It looks like your Bava uses the Samsung diodes but Mars does not. I'm in no way a supporter of HLG and their over priced "Quantum boards".
