“I mounted these little lights in the bottom of a wood fireplace mantel. Used a 2 3/4in hole saw and the lights fit nicely with a room to adjust them slightly. I combined these lights with a Lutron Caséta wireless dimmer switch and the lights dim flawlessly and integrate with my smart home. They are very bright on high but dim down to a satisfactory level on their lowest setting. Great lights if you need something small, adjustable, flush mounted, and dimmable.”
