A total internal reflection (TIR) lens has an integrated lamp cover adapted to a lamp of a desired form factor (e.g., PAR-38). The size and shape of the TIR lens can be adapted to optimize the light output of the lamp with little regard to the desired form factor. The integrated lamp cover can extend the front surface of the TIR lens in a direction transverse from the optical axis.
