hehe Obviously that's not a good idea. Do you think the 8 ohms would
give me the best brightness and still protect the LED enough? I've got
10ohms resistors (1/8 and 1/4W) laying around so I may toss one of
those in and call it done. How does that sound?

Thanks again!




Measure the current, don't exceed 20mA or the LED will not last long.

Don't I want (nominally) 112mA?

I put a 10 ohm resistor in and get 90mA on the ammeter. Nice bright
backlight too.
