FLI Products 6 Inch 750 Lumen Contemporary Dimmable 1-Light Plastic Flush Mount Lights for Hallway, Dining Room, Outdoor

I needed to replace some hallway lights at my inlaws and these matched the original lights. It was only a matter of taking out the mounting screws, disconnecting the power, taking the wire nuts off, and then installing the new lights. The lights are LED and are built into the light fixture itself. This is a good thing as you'll never have to change light bulbs but the downside is when the LED's start to go then the entire fixture will have to be replaced. I replaced two of these and total time spent was less than a half hour. Just make sure to cut off the power prior to installation or you may get a little extra zap in your day.
