Take a look at the link below. Page 9 lists a range for this LED @4250 k, and gives you some idea of luminous flux at 1050 mA, which happens to be right about the default max of the HIVE driver (1000 mA). You will also see some CRI data for those BINS.
Short answer, Haiku is probably around 360 lumens and 75 CRI. I bought my first Haiku with this LED and driver combo, and I was happy with it.
