Bill,
I have red LEDs on my Spyder, and amber LEDs on my Europa. Both are awesome, and I find them extremely useful, particularly in a dark environment. The amber LEDs are particularly bright - if brightness is an issue and you want the LEDs, you could ask the good folks in Santa Rosa to put a dimmer switch in for you. Anyway, like others here, all of my future Alembic purchases will include LEDs. If you can get them, do so. You won't be disappointed.
Regards,
Alan
