That's true but it makes it difficult to get relevant figures for "non-common" drive currents.
I'm really liking the C version at 1.05 amps. Output is about identical to the 3590 at 2.1 amps but is running at 70 watts rather than 75 watts. Not a huge gain, but also comes with a price drop.
The C version at .7 amps (about 46 watts) might be a good sub for 3590 at 50 watts, but I'm having issues getting accurate data. With the 3500K 80CRI chip at 855ma and 25C the graph indicates 52% of nominal which comes out to 9846 lumens. However the common drive currents charts lists the 3500/80C variant at 855ma as 10757 lumens. Assuming the chart is correct this leaves me to try and determine 50C LPW for .7 amps based on the 25 and 85C LPW at .855 which means I'm basically guessing. It looks like it should be around 190 LPW but I have no way to be sure.
If it's close to correct this would put the 3500C at 46 watts about 8740 lumens while the 3590 at 50 watts is about 8900 lumens. Again very similar result for a few watts less and a nice price drop.
