New Tektite LT-2 and LT-3

I have a question about the new LED retrofits from Tektite. I have an LT-1 in MM-AAA and is fine for many non-demanding tasks and activities. The LT-1 was previously marketed as retrofit for the MM AA and AAA.
I have now seen Tektite selling:
LT-1 For the MM AA
LT-2 For the MM AAA
LT-3 For the MM Solitaire.

While I understand the LT-3 is much smaller and is designed for 1-cell operations, what the differences among the LT-1 and the LT-2 are?
The Tektite website do not show any technical information on the LT-2 and the LT-3.

TIA

Anthony

the new lt1 does not fit the aaa mini mag so this is where the lt2 comes into play. i would assume that the output would be simaler to the lt1
