long day. im tired. blew up a 3590 thanks to the most non-intuitive ammeter ever(DOH)
quick and dirty test of 1400 mA and below. i have a better benchtop power supply coming and will do further testing and some spectra as well
setup: bare cobs with no optics or reflectors, at 15" in freespace with no nearby reflective surfaces, 140mm pinfin with 120 mm fan sitting atop it, HLG-185H-C1400B
PAR measurements with Li-Cor LI250A w/ LI190 Quantum sensor
'supra-style' graph:
x axis = watts measured at COBs
y axis = ppfd in umol/W
takeways:
citi looking to pass cree in efficiency above 50w as mfr data suggests. impressive performance for a 2700k. 3500k citi should be ~5% higher. ill try to run 5000k citi vs 5000k db bin 3590 later today
cutters run soft were not as efficient but i was unable to test them to their full potential (higher currents)
