Bought for new construction in my basement. They are mounted on a soffit below my duct at about 6.5 feet and the light at full power at that height is quite blinding. I set the dimmer to around 60% and that seems to have helped. It's not finished yet, so I can't attest to the full finished effect yet. These lights are very small. The 3 inch measurement includes trimming, so don't assume the lantern itself is 3 inches wide. Another thing to note is that the box is very small. Small, like 4.2 cubic inches, and the wires attached to the transformer take up 50% of the space in the box. I ended up cutting them off and replacing the included push-in connectors with small twist-wire nuts so I could get two 14-2 cables a few inches in. Cable clamps are also not included, but the standard 1/2" nm cable connector works great in cutouts.
