It is in my contract for Lightolier recessed lighting. Contractor wants to substitute Nora. Is this an equal substitute or should I reject? If I accept, is there a difference in price?

Not familiar with Nora, but looking at the catalog, looks very similar with Halo and Juno.

While LOL makes a residential grade, it usually is the most expensive, and it is shown in the quality .

Nora is only available through dealers and distributors so can't help with the pricing difference.

I do not believe that it is an even trade.
