I just installed 6 of these lights on my dining room ceiling and they look great. I wanted to direct the light onto the walls (art) so I went with dimmable LED lighting. The light quality is excellent, pure white like a 60-75W incandescent lamp, not greenish. very happy. Although they are 5 inches tall, the adjustable open lamp head part looks more like 4 inches (unobtrusive), which I also find positive. Just make sure your dimmer is suitable for LEDs.
