In Maryland expect to pay $150-$300 per light. The installation cost will vary depending on the type of light, ceiling height, and ceiling finish. Most electrical contractors have a preferred brand they like to use for all their recessed lighting in which case the biggest factor is the labor. High ceiling like in a foyer or vaulted ceiling in the living room will greatly impact the price. Even having a 10-foot ceiling opposed to the standard 8 foot will bring the price up a bit because of the increased labor time. A ceiling made of plaster will cost more than a drywall ceiling.
