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.
A light-emitting diode (LED) is a special kind of diode that glows when electricity passes through it. Most LEDs are made from a semi-conducting material called gallium arsenide phosphide. LEDs can be bought in a range of colours. They can also be bought in forms that will switch between two colours (bi-colour), three colours (tri-colour) or emit infra-red light. In common with all diodes, the LED will only allow current to pass in one direction.
