These look fabulous, very bright at night. Added them to our HOA condo complex. Great that you can direct them down on the stairs or both directions in the common areas. Constant positive feedback from owners and visitors. We will see how long they last as they are on all night.
Difficult to install as others pointed out. Required an adapter in multiple cases. Our wall holes were also larger than the cube in some places so we've had to find...creative solutions...for hiding that.
Since they are rated for outdoor use, used 3 in bathroom to accentuate stone and decorative planters. Beautiful. Adjustable up and down light. Perfect size.
