That was flip chip opto http://fcopto.comLOL! Does anyone remember the guy (Chinese sales rep) who was here years ago and had COBs that could be printed to look like yin/yang symbols, etc.? And the COBs he ws advertising could be run over by an army vehicle and not go out. In fact, I think that's what they were trying to sell to the army -lights that wouldn't go out under almost any circumstances. Anyone? I remember the guy was very good natured...of course he took a lot of shit from the naysayers and disappeared, but some of those videos he posted were funny! I never saw any more about those COBs anywhere after that. I guess that's the testament to them...unless the army DID pick them up! Who knows?
I just looked at the datasheet for the duet 2400w. The numbers are poor at max current (I didn't see a nominal current listed). If it was driven at 600 watts it would provide about 1.5 umol/j and 1.6 umol/j at 400 watts. The Apollo 900 at 520w is only 110 LPW so not great. Looks like they haven't updated since 2018.
