Holy cow this light is bright! I replaced two of my vanity lights with two of these 3-light fixtures and it floods my whole bathroom with brightness. I had no idea how dim my prior lights were until I installed these!Installation was a breeze, minus some crazy wiring that the prior homeowners did that took us a little longer to correct first. Not a reflection of this product though.There are a total of four screws on each 3-light fixture that mount the lights to the base plate - two on the top and two on the underside. For this reason, you need to have adequate clearance above the lights (at least 2”, more if you have big hands) to be able to fasten the top screws in place. You cannot just use the bottom two mounting screws as the lights themselves have some heft (lots of glass crystals, after all). May not be a problem for most people but I had just enough clearance to get my dainty hands in to fasten the top screws in place.Besides being insanely bright, the lights are quite beautiful and add some elegance to the bathroom. Mine are mounted directly onto a wall mirror, and the polished chrome base actually looks like an extension of the mirror because it is so reflective.The only complaint I have, and it’s minor, is that the wire prongs that hold on the crystals are a bit pokey and I kept jabbing myself while I was trying to wipe off the fingerprints post installation. On the plus side, extra crystals were provided with each light in the event you need to replace any.
