method was a bit rough and the white light LED wasn't the ideal source, but it is good enough to suggest that the 1600 is pretty capable for a DSLR-type CMOS chip - confirms a gut feeling assessment from using the two cameras.

Would your results indicate max QE around 50%, possibly in green? BTW, looks like a fun activity measuring relative QE with a LED
