Obviously, the lili ledy light saber has a thicker tip then the kenner, but from my view at looking at glasslite and lili ledy the lightsabers look the same....can someone confirm, or deny this is the case...

Ledy and Glasslite sabers are different sabers

Easiest way to tell the 2 apart is the Ledy saber is cut off the mold from the top of the hilt,
and the Glasslite saber is cut off the mold from the back of the hilt.
Ledy sabers will sometimes have letters on the hilt,
Glasslite sabers have some speckled "glittery" particles within the plastic.
