Review on 💡 Ultra-Bright Lithonia Lighting WF4 27K30K35K 90CRI: Unbeatable Illumination! by Bill Snyder

I put 21 of these in my 16'X25' living room, it was the first thing I did after rocking the sheet and they lit my living room so well my smooth flat V- Fairing came out with a few flaws. I have another 20 4" and 10 6" for the rest of the house. My 4" hole saw is either under 4" or slightly over 4". I carefully trimmed the holes for a snug fit, not a deal breaker. I also used Lutron Maestro dimmer switches which are fantastic with this bright, beautifully subdued and bright stadium.
