Economy Lite:
-No IFE. (crew disable the screens/control through the Panasonic system)
-Food/Bev's are extra cost, select what you want when booking your ticket.
-Dedicated cabin using a movable curtain/divider (Lite cabin is the last rows of the A/C, divider positioned according to how many seats sold as 'Lite')
-Seat pitch reamins the same.
I'm also guessing there will be baggage restrictions, and bugger all 'rockstar' treatment.
