Will the Pelican M6 LED head be available >>

separate from the body and will it fit the M6 lithium body (similar to the SF E2e, KL1 combination)?

My guess would be no. Unlike the E(x)e /KL1 combination, the PM6 front end is 2 parts with the head and LA module separate . At some point, the LED module might be available as a replacement part but I even doubt that since it is likely not to be replaced except in a warranty situation. Further wild guessing suggests that if one wanted both incan and LED one might buy the LED version light and then be able to purchase a replacement incan LA for swapping out. Until we see the actual lights, it is unknown whether there are any differences in geometry or assembly that would preclude an interchangability.

I rely heavily on my sig line for this post.
