I have an older KL1 head that I have replaced the stock LED :green: with a K2 TFFC diode driven at 1A. I am trying to figure out what reflector or optic would work best. I am currently using a fraen LP optic that produces a square beam. Any ideas?

Nice upgrade.
With a single die emitter like a K2 you have many choices - perhaps too many. The best way is to look at beam shots posted and see which ones you like. Seriously there is that much range.
Do you want more flood, a real thrower, etc.
The square beam is typical for an optic which is exactly in focus. What I usually do, is go to photon fanatic and buy several that will work and just try them out.

Thanks for the info. I may post pictures but my phone is my only camera for the time being and it takes poor quality pictures. I 'm thinking I'll try the McR18
