GE Dehumidifier Model Numbers--Differences Between Them?

[blackstone]

In the market for a GE dehumidifier, 35 pint. Came across these 3 model numbers. What is the difference between the models? Date of manufacture? Would the higher letters (LB vs LA; HR vs HL) signify a newer production date? Can't really look online, since those website ask for serial numbers.
