[SML] Difference between LED-specific 50-degree EDLT and "normal" EDLT?

[Jon Ares]

Hi - wondering if anyone has any empirical knowledge between ETC's
"LED-specific 50-degree EDLT lens tubes", versus the "standard" EDLT
50-degree lens tube? (Other than very small price difference).   My
local salesdude hasn't seen them side-by-side, so he doesn't know
either.... anyone used both?

For what it's worth, these lenses would be used on either ColorSource
or S4LED Series II fixtures, with gobos, but not incandescent
fixtures.  TIA!

 - Jon
