Inner vs outer lysosomal membranes

This is a quick observation perhaps meaningful (well i think it is relevant to the interaction of perfluorodecyl iodide within the lysosome). It appears to me like the inner lysosomal membrane is quite a bit thinner (meaning probably 1) a difference in the lipid membrane constituents or 2) the loss of some of the intrinsic membrane proteins.  I measured just one area of such a lysosome, and the outer lysosomal membrane seems to be about twice as thick as that which abuts the perfluorodecyl iodide crystalline inclusion.
