With the latest versions, which has highest throw? Widest spill? Other considerations?
I linked to it earlier today when I quoted you in another thread. But X40 vs K40M is well covered here, and will probably be even more when I have added more to that thread. Feel free to ask any questions if I have not covered anything you want to know or already know about the lights.
I cant comment on the TN30. I can add that in JM`s review of the K40M you can see a comparison with TN35 if that is of interest.
