Thanks for letting me know, guessing its about the same as lm561c?
How do you check if you got a genuine
lm561c with s6 bin? And does the lm561b+ run hotter than c?
Thanks for all the helpful info on this forum.

i just got some led strips and each diode has a small silver dot in it.
is this normal? looks like the soldering melted the yellow phosphide?
