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.
LEDâs produce uniform light dispersion and light output is dispersed evenly over the lens which make them brighter than incandescent lamps. LEDâs are very energy efficient producing up to 90 percent light output with very little heat while incandescent bulbs use up to 90 percent of their energy generating heat. Incandescent lamps only produce white light which must be filtered for traffic signal use, and this leads to an additional loss in energy.
