Top view and quarter top of the A2 Led head (center), flanked by other heads : LX2 (left) and KE2G/EDCL2-T (right).
Last photo are the bottom-to-bottom shot of the LX2 and A2Led heads. Lower portion of the head assembly are the same. The lower portion is also similar to the KX-series, but more externally squared.
Hope these help.
