However, now I'm considering which leds to start with and have options for
0603 leds with a dome lens or flat lens. There will be lightpipes in front
of the leds to bring light to the front panel, so is there any advantage or
disadvantage to the type of lens?


My guess is that the dome lenses have narrower light spread, and that this
will make the light enter the lightpipe at a more straight angle. This
should maximize the light transfer through the pipe and - more importantly
- minimize losses both at lightpipe entrance and via inner reflections.
