Cost of the Lights. Low-end recessed lights cost between $20 and $60 each. Higher-end, low-voltage recessed lighting can cost $75 to $150 or more per light. Each light requires a housing that goes into the ceiling and a trim that covers gaps between the housing and the drywall.
Key Differences Between LED and CFL Bulbs. 1  The LED bulb stands for Light Emitting Diode, and CFL stands for Compact Fluorescent Light. 2  LED bulbs are more energy efficient than CFLs. 3  The LED bulb consumes less electricity than its counterpart CFL 75% a year in energy cost.
Compact fluorescent bulbs, also known as CFLs, contain a fluorescent tube and ballast in a single unit, and are designed to replace incandescent bulbs. A 23- to 27-watt CFL provides the same amount of light as a traditional 100-watt incandescent bulb while consuming about 75 percent less energy.
