LRL (Lite) modules compatible with LR?

I am in a small bind right now till we get more LR modules to arrive. On a short distance run under 10Km can I use a LRL (Lite) module and the opposite end a LR module? The length of the cable is within the building just from floor to floor reach so it maybe at best 500ft (Well under the 1Km for a LRL). We ran out of the LR modules and only a few LRL modules on hand.
