What does LT stand for on off road tires?

I’m looking for some off road tires for my Jeep and some of them are the same size (33/12.50) but after that, they have 15LT, 16LT, 16.5LT, etc. I want to know what the LT stands for and what differences they have.

    LT = Light Truck and the number corresponds to the wheel diameter
