All right... I'm starting a new topic because I think some of you
might not be taking me seriously anymore...
I have a setup that is giving a 500us pulse to an LED every 15ms.
I don't remember the LED being so dimm when driven this way. I'm trying
squeeze every bit of brightness out of it.
I have HP LEDs, part number HLMP-3507, Bin F, Color 5.
The data sheet can be found here:

I'm not sure how to understand Figure 15, which sets limits for pulsed
operation
When running the LED off of a 100ohm resistor with a 12v supply I get a
6v voltage drop as seen on a scope. This would seem to indicate 60ma
for 500us. I'd really like to get it up to 120ma if possible, but the
data sheet says 90ma?
Any ideas???
Thanks,
Grant
