I've had a few people email
I've had a few people email me about the XR-E's - they're looking like a very good option right now. The K2's also don't gain a lot of brightness when you increase the current from 1A to 1.5A.
When time allows, I want to get a few combinations of LEDs and optics and see where the best combination of brightness/cost/power usage is.
I wasn't aware of the full beam width/half beam width difference - thanks for the info!
