There are a lot of different kinds of LED on the market these days. I'm
trying to understand some of the distinctions.
I'm seeing some called "low-current" (e.g., Fairchild HLMP-D150). They
don't seem to be any different than normal LEDs, except they're
characterized at low currents. But after all, any LED works at low
current - they're generally pretty linear over several decades, far as I can
tell from the datasheets.
So, what makes something be a "low-current" LED?
And, if I'm interested in operation as a panel indicator at 1mA or so,
should I be looking at "low-current" or at "ultra-bright" LED's, to get best
visibility?
Thanks,
