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.
CFLs contain about 25% of harmful blue light and LEDs contain about 35% of harmful blue light. Interestingly, the cooler the white LED, the higher the blue proportion. And by 2020, 90% of all of our light sources are estimated to be LED lighting. So, our exposure to blue light is everywhere and only increasing.
