That's correct. The fast one is called NSL-32SR3. Or are there even faster
versions? The SR3 is the fastest of the ones Farnell sells, at least.
I tried both the NSL-32 and the NSL-32SR3, 25 pcs of each type. The problem
with the NSL-32, apart from speed, is that they differ a lot between them.
Th resistance at a given LED current can vary more than 100%. The NSL-32SR3
is much better in this respect. And faster.
